Nt1310 Unit 6 Lab Report
The purpose of lab 1 was to purify the vanillin (individually) as well as an unknown (with a
partner). By recrystallizing both compounds, students were able to determine the percent recovery
of each solid and get one step closer to determining our unknown compound. For lab 2, the purpose
was to determine the percent recovery both solids (vanillin and the unknown) as well as determining
the melting point ranges. By determining the melting point ranges, we would be able to identify our
unknown. For the first lab, students worked individually to purify vanillin, but worked in pairs in
order to purify an unknown. We began the process of purifying vanillin by weighing it out and
dissolved in water, afterwards we placed the solution in an ice bath. After a minutes, we vacuumed
out the vanillin, in order to obtain the crystals. In general, recrystallization is used to purify
compounds–which was the purpose of this la . As for the unknown solid, a similar process was
conducted. However, for the unknown, students had to determine the right solvent in which the

We first, determined the percent recovery of both vanillin and unknown and then determined the
melting range of both compounds. Determining the melting point range, verifies whether or not
students purified the compounds properly. Pure compounds tend to have smaller and higher melting
points than the original compound. Students worked individually when determining the melting
range of vanillin–we were to determine the melting ranges of crude vanillin and the recrystallized
vanillin made in the first lab. Moreover, students worked in pairs when determining the melting
range of the unknown by using a commercial apparatus. For both solids, we watched the crystals

Microorganisms In Environment
The risk assessment associated with e.g. detecting microorganisms in the environment and methods
for monitoring microbe concentration could pose a challenge as compared to genetically modified
(GM) crops (SACGM., 2015). This is because microbial reproduction and their capability for
survival in wide environmental conditions is not yet studied thus, possible risks remain unknown
especially once released into the environment. One would design experiments to close the
knowledge gap e.g. in behaviour and the fate of microbes in the environment though it is currently a
big challenge. Despite challenges in knowledge gap, conducting and designing experiments in
containment is vital in acquiring sufficient data to inform synthetic biology ... Show more content on

Risk assessment of genetically modified microbes for deliberate release in feed and food
applications has not been approved however, there are other applications where similar methods
have not hindered innovation (Jörg Ettenauer et al, 2015). An example is the use of novel
applications such as the production of animal and human vaccines and gene therapy. It is possible
that the acquired experience from the use of such methods could be applied to inform and encourage
similar approaches to food and feed applications. There is however a regulatory mechanism in place
where if the microbes are deemed safe, Companies can obtain an exemption from the contained use
directive (Jörg Ettenauer et al, 2015). Whether that can apply to food and feed applications is not yet
clear. An example is where an application applied for an exemption for a bacterial biosensor (E
coli), to detect arsenic in ground water (Jörg Ettenauer et al, 2015). On detecting arsenic levels in
ground water, the biosensor is engineered to turn green for safe levels or violet for dangerous levels,

Determination of Vanillin in Imitation Vanilla Essence
Chloe Nolan 14832679
Introduction
4–hydroxy–3–methoxybenzaldehyde or as it is better known, vanillin is most commonly used to
create imitation vanilla essence (Southam, 2013).
Figure 1: vanillin structure
Vanillin was first synthesised from eugenol from 1874 – 2001, from where it was later made from
lignin– containing sulphite liquor which is a by–product of wood pulp processing in paper pulp
manufacturing, most recently it is more common to find vanillin made from guaiacol and glyoxlic
acid (3D chem, 2013). Vanillin is most commonly found in food flavour formulations, perfumes and
fragrances and has been used in drugs used by those who suffer from Parkinson's disease ... Show

Experimental
Diluted essence (10ml, 100 times diluted) was pipetted into a 100ml separating funnel. 20ml of
dichloromethane was added to the diluted essence. The funnel was then shaken vigorously for 2
minutes with gas being release occasionally. The organic phase (lower layer) was released into a
100ml beaker and another 20 ml of dichloromethane was added to the funnel and shaken vigorously
for another 2 minutes. The organic phase (lower layer) was again released into the 100 ml beaker.
The contents of the funnel were disposed of. The organic phase was then added back into the
separating funnel with 40ml of 0.1M sodium hydroxide solution and shaken well for 2 minutes. The
organic phase was released and disposed of and the aqueous phase was kept and transferred to a
250ml volumetric flask and the volume was made up with 0.1M sodium hydroxide. Standards were
then made using the 50mg/L standard provided and mixing with 0.1M sodium hydroxide to create
standards with 1,2,3,4,5 mg/L concentrations. Each solution was run through the UV – Visible

Exp.11) Identification of unknown ketones. Introduction: Given five samples of a known ketone
derivative, the purpose of this experiment is to identify which unknown ketone derivative
corresponds to the five known samples. In other words, using specific methods of compound
detection, it is possible to match an unknown compound with a known compound because similar
compounds will display similar characteristics. In this experiment, identification of the unknown
ketone is accomplished through thin layer chromatography, melting point, and 1H–NMR

As mentioned in the introduction, a sample of the unknown is placed in the spectrometer, more
specifically, in the midst of a magnetic field.[1] To conclude, it is evident from the Rf values
obtained that unknown # 3 Rf is closest to that of 2 – Octanone. With a 7.2 % error, this can be due
to the reagent being diluted with too much ethanol or still containing traces of the acid, however if
traces of the acid are present then the melting point[3] should be significantly lower. From the
melting points we can determine that unknown # 3's melting point is closest to that of 2 – Octanone
with an 8.6% error. This can be attributed by either the unknown being diluted with too much
ethanol and water or the mixture containing traces of acid. However, as aforementioned, traces of
acid would only lower the melting point not raise it, therefore it is unlikely that traces of acid can be
attributed to the error.[3] From the H NMR spectrum, integration suggests that at 1.9 and 2.25 there
is some indication of possible ketone fragments. 1H–NMR Spectra for 2–octanone: [5] 2–
Octanone's structure contains a hydrocarbon chain therefore the spectrum has indicated the presence
of methyl groups giving further evidence that the unknown is in fact 2–Octanone. To conclude,

TLC Analysis And Synthesis Of Cinnamic Acid
The recrystallized cinnamic acid was obtained from the previous lab. It was a white and flaky
powder and had a very slight sweet/spicy smell. When weighed, the recrystallized cinnamic acid
was only .340 g. The starting amount was .500 g, so the percent recovery was 68.0%. ((.34g/.50g) x
100%)). The low percent recovery may have been due to the addition of too much solvent(book).
Last lab, 90.0 mL of solvent was used to dissolve the cinnamic acid, which was the maximum
amount directed by the instructor. The melting point range was analyzed to be 128.5 C– 131 C. This
was a narrow range for the melting point, indicating purity. This melting range is close to cinnamic

The cinnamic acid and methanol mixture was yellow and clear. .500 mL of concentrated sulfuric
acid was slowly added to the mixture. The mixture was still yellow and clear. A reflux condenser
was added to the flask. The mixture stirred for one hour: 3:44 pm– 4:44pm. During the hour of
stirring, a TLC analysis was made. The substances compared was the recrystallized cinnamic acid,
cinnamaldehyde, and aged cinnamon oil. The cinnamon oil was 6 weeks old. It was a yellow solid
gel with a small amount of liquid. The oil has a slight cinnamon smell. The stationary phase was
silica gel and the mobile phase was ethanol: hexane (2:6) and 2 drops of acetic acid. The cinnamic
acid and cinnamaldehyde were diluted in acetone and the cinnamon oil was diluted in hexane.
However, when analyzed, no compounds showed up under the UV light. It was realized by the lab
professor that discarded, diluted acetone was used instead of just acetone. The cinnamic acid and

Pros And Cons Of Bruichladdich
Bruichladdich is no stranger to No Age Statement whisky. In fact over the past ten or twelve years
they've probably been one of the most visible proponents of the concept. I think this approach was
first viewed by the distillery as a necessary maneuver in order to get whisky on the shelves
throughout the first decade of production after their 2001 reopening.
Considering how fundamentally opposed I am to the idea of opaque marketing with whisky, I
imagine it's somewhat surprising (even to myself, if I'm to be honest) how much I adore and support
Bruichladdich.
Let's face it...no other distillery has done as much to reinvigorate the whisky world over the last few
years as Bruichladdich. They've pushed hard for higher bottling strengths – first 46% as a standard,
and now 50%. They've foregone artificial colouring. They've made a mockery of the concept of
chill–filtration. Their employment of local labour is staggering, especially viewed in contrast to the
two–man crews running some of Diageo's multi–million litre producers. Their innovative cask play,
phenol manipulation (and exploitation!), terroir–first approach, experiments with organic barley,

acclaim and widespread demand that the distillery finally had to step away from the idea of the

Nutella Makes Up for Cocoa Shortage During World War II
The period was World War II there was a shortage of cocoa at the time; Mr. Pietro Ferrero, a pastry
maker founder of the Ferrero company thought that using hazelnuts and mixing it with skim milk
and a little of chocolate would be a good way to appease the short supply of cocoa by allowing
chocolate to last longer. This still being the product's two main ingredients today; hazelnut and
cocoa. In Italy, during the 1940s; Mr. Ferrero created the Nutella spread. In its earliest form, Nutella
a hazel nut and chocolate spread was originally called "pasta Gianduja" this of course was the Italian
term, "pasta" means paste and the "Gianduja" was the name of a famous character in the region in
Italy. The paste was first introduced by being made in the loaves of bread wrapped in tinfoil, used to
make sandwiches. A product popular to children, the bread was tossed away and the paste was most
favored. Later workers decided it would be best if the spread was made easier to spread on the bread
then being known as "Supercrema Gianduja", thus being processed in large jars with a yellow
sticker on the middle and a red lid. Soon after in 1964 "Pasta Gianduja" or "Supercrema Gianduja"
the product was named Nutella: "nut" being the origin of the product and "ella" a soft Italian term.
Nutella rapidly became popular among Italy. Just 25 years ago, in 1983 the Ferrero Company

Using the ethanol as the solvent produces a more environmentally favorable conditions, and the
bleach combined with sodium iodide produces an efficient and selective (mono–) product. Once the
final product had been recrystallized with isopropanol, the crystal were collected via vacuum
filtration. These crystals took some time to dry out, but they eventually were dry enough to scrape
out for further evaluation. After an IR was run, it was quite obvious the product was surely
Iodovanillin. Further analysis of the melting point was taken to ensure the final product was the
desired Iodovanillin. A few sources of potential error are as follows: loss of product on glassware
throughout the experiment, inadequate measuring of chemicals, "impure" chemicals being worked
with, and loss of final product during crystallization processes. Questions: 1. The HC=O is a

Lab Analysis Of Horseradish Peroxidase Type 1
Horseradish peroxidase Type 1 was used in this laboratory experiment, it was an enzyme that helped
catalyze the oxidative coupling of vanillin to produce divanillin. The role of the enzyme is to
increase the rate of the overall chemical reaction to reduce reaction time, therefore making the
reaction process faster. The Horseradish peroxidase Type 1 achieved this by decreasing the
activation energy required for a chemical to react, thus allowing the reaction to process through a
lower activation energy, which increases the reaction rate and makes the reaction faster.
Reaction:
In this experiment, the change of pH was also a key step of the reaction because the pH factors in
the stability of an enzyme. Since we used an enzyme in this reaction, the pH levels of the solution
needed to change first before adding the Horseradish peroxidase Type 1. The reason for changing
the pH levels is to ensure that the enzyme will work during the reaction and having a high or
extreme pH causes the denature an enzyme. After 0.50 grams of Vanillin were dissolved in
Deionized water, we added 0.1 M acetic acid for the pH levels to drop until the pH was 4 which was
the desired pH level.
The addition of hydrogen peroxide, , was to split the peroxide bond making free radicals to create

What Are The Advantages And Disadvantages Of Ester
Any chemically–defined substance with flavoring properties either formed by chemical synthesis or
obtained from material of plant or animal origin is known as flavoring substance. Flavor enhancer is
known as any substance that when added to food is capable of enhancing or improving the flavor of
the food (Food Act & Regulation 1983). Many spices, natural and synthetic flavorings enhance the
taste of the foods. Many artificial flavorings are esters. Some esters occur naturally while others are
produced artificially. The esters have distinctive odors that resemble natural flavors such as peach,
rum, pineapple and maple. Foods such as candies, ice cream, cakes and syrups are flavored
artificially by esters.

They ensure that foods is attractive and conserves its color. Some flavouring even give strong taste
to the foods or enhance the taste. As many benefits as food flavourings have, however, they also
have a good number of disadvantages. A number of additives can cause allergic reactions. Some of
the flavourings are likely to cause allergy–like reactions and hypersensitivity. They can also cause
hyperactivity in some children. Monosodium glutamate (MSG) are widely used in everything from
pet food and sausages to soda, snacks and pastries. Other food additives that are known to cause
allergic reactions in some people include the artificial coloring carmine, tragacanth gum and sodium
benzoate. Much of the enjoyment of food comes from the way it looks. The problem is that once the
foods is store for a long time,the original flavouring is decrease. To make the product more enticing,
manufacturers sometimes add flavouring. For example,oranges juice sometimes are added with
artificial flavouring to make them taste better. Many fruit drinks make use of food colorings, as do
some precooked meats, soy sauce and even beer. The flavor enhancer monosodium glutamate, or
MSG, helps bring out the flavor of the foods it is used in. The problem with this is that
manufacturers can reduce the amount of the real ingredient and still have the same strong flavor in
the final product. So a can of chicken soup could contain very little chicken, and an orange juice

Hexane was added with the help of a Pasteur pipette and the sample was allowed to seep into the
silica. Hexane (150ml) was then passed through the column, eluting a yellow extract which was
continually allowed to be re–eluted until the yellow colouration lightened significantly before the
addition of the next solvent of higher polarity. This was repeated for the remaining solvents (ethyl

Pros And Cons Of Natural Vanillin
In 2015, young friends of the earth Europe launched a campaign referred to as "Extreme Genetic
Engineering in your ice cream". It campaigned against "natural" vanillin produced through synthetic
biology or "extreme genetic engineering". An example is Evolva a Swedish company that produces
pure vanillin by fermenting sugars using genetically modified yeast (Diederik VH, 2015). Evolva
acknowledges that the public does not welcome the use of synthetic biology or GM products due to
little or no public awareness for such products, but there are other means of overcoming such
challenges. One example is when the company asked for permission to label synthetic biology
produced vanillin as "natural" since the product is produced through a natural fermentation process,
just like alcohol fermentation process. Although the permit was granted, and the products labelled as
natural in the market, there is still pressure from NGO's such as the young friends of the earth as
they campaign against such innovative products (Diederik VH, 2015). It is possible that if pressure
group campaigns are successful in persuading other companies in the supply chain that purchase the
raw materials for their products, production innovation could be affected. One example is when
young friends of the earth campaigned against synthetic vanillin to the extent that it demanded
assurance from major ice cream producers e.g. a European ice cream company Haagen Dasz

With the given fact that inhaling vape is a dangerous method of smoking due to the amount of
nicotine toxins in it, it does not justify that nicotine is the only chemical that is said to harmful in the
vape juice. E–cigarettes contain flavors that can be toxic to humans such that "several cinnamon–
flavored e–cig liquids contained a chemical, cinnamaldehyde that researchers said was highly toxic
to humans cells in lab tests." (Hiles 1). This justifys the fact that the chemicals found in e–cig juices
are toxic to our cells. Just because E–cigarettes use vapor instead of smoke does not justify the
vapor to be safe as "Testing of some e–cigarette products found the vapor to contain known
carcinogens and toxic chemicals (such as formaldehyde and acetaldehyde), as well as potentially
toxic metal nanoparticles from the vaporizing mechanism" ("Electronic Cigarettes"). Vaping
nicotine can also be considered dangerous as it can cause side effects that are harmful. Nicotine can
be a major risk factor not only in tobacco products: "Dermal contact with even small quantities of
liquid nicotine can cause dizziness, vomiting and seizures. Ingestion can be deadly" (Milov). Many
chemicals are misinterpreted because they are safe in solid forms such that are found in food but
when inhaled can cause major damage. Many industries have committed actions to warn the public
about flavoring with known toxins in them "The U.S flavoring industry issued a list of 27 'high
priority' flavoring chemicals that, while safe in food, may pose a risk of respiratory injury and for

Abstract
Objective: Doxorubicin (DOX) is an anticancer drug that is known to increase oxidative stress in
several organs. Our objective was to evaluate the possible cardioprotective and nephroprotective
effects of guava leaf extract (GLE) and olive leaf extract (OLE) on DOX–induced toxicity in rats.
Methods: Forty adult male albino rats were randomly divided into 4 groups of 10 rats each, as
follows: a normal control group, a DOX group (a single dose of DOX; 30 mg/kg intraperitoneally),
a GLE group (500 mg GLE/kg body weight), and an OLE group (500 mg OLE/kg body weight) for
12 d. DOX was administered in the DOX, GLE, and OLE rats, which were killed 4 d after DOX
administration.
Results: DOX injection resulted in a significant elevation in serum lactate dehydrogenase, kinase–
MB, total protein, urea, and creatinine. Cardiac as well as renal glutathione (GSH) and catalase
(CAT) were significantly decreased, whereas tissue lipid peroxidation significantly increased.
Pretreatment with GLE and OLE significantly reduced the elevated concentrations of serum lactate
dehydrogenase, kinase–MB, urea, and creatinine (P < 0.05). GLE and OLE increased cardiac as well
as renal GSH and CAT concentrations and decreased malondialdehyde concentrations.
Conclusions:

The Discovery Of Coffee 's Coffee
The discovery of coffee had changed the cultivation and the way of trading in the civilisation.
Although the origin of the coffee is not clear but for sure coffee is wide spread around the world and
is loved by billions of coffee drinker. The difference in coffee varieties, geographical location,
climates and agriculture practices across the world has brought different sensory qualities to the
coffee. This is because the flavour of coffee begins early in the plantation stage where flavour
precursor forms as the coffee berries develop and ripe. For example, caffeine, a nitrogenous

The origins and reactions make coffee flavour a complexity science to study and also explain why
coffees exhibit such diverse, unique and specific flavours. (Sunarharum et al., 2004)
Sunarharum et al. (2004) summarised that coffee volatiles compounds consist of a wide range of
chemical class like hydrocarbons, alcohols, aldehydes, ketones, carboxylic acids, ester, pyrazines,
sulphur compounds, furans, phenols among others. Furans are one of the aroma active compound
quantitatively high which show significant concentration found in roasted coffee and brew coffee
beverage. Furans are usually formed through thermal degradation of carbohydrates, ascorbic acid or
unsaturated fatty acid during roasting. The volatile exhibit malty and sweet roasted aroma with a
relatively high sensory threshold but due to their high concentration, furans still show importance in
coffee aroma. (Flament, 2002) Roasting coffee beans also produced furanones, mainly by Maillard
reaction and other side reaction. (Gloess, et al., 2014) Furanones in roasted coffee are as abundant as
furans which shows significant volatile properties and sensory potency. As seen in Coffee Flavour
Chemistry (2002), 3–Furanone is one of the furanone commonly found in roasted coffee and is
responsible for the intensively fruity jam–like and sweet caramel aroma. (Akiyama, et al., 2007)

1.1.1 Schiff Base
The condensation product of primary amines with active carbonyl compounds have resulted in the
formation of Schiff base compound. This has been reported by Hugo Schiff in 1864. Schiff base
compound contain azomethine –C≡N with a general formula RHC=N–R' where R and R' are alkyl,
aryl, cyclo alkyl or heterocyclic groups which may be variously substituted. These compounds are
also known as anils, imines or azomethines (Mishra N. et al, 2013). Structurally, a Schiff base is a
nitrogen analogue of an aldehyde or ketone in which the carbonyl group (C=O) has been replaced by
an imine or azomethine group (Figure 1.1) (Abu–Dief M.A et al, 2015).

The development of new antibacterial agents with novel and more efficient mechanisms of action is
definitely an urgent medical need. Schiff bases have been pointed to as promising antibacterial
agents (Brodowska K. et al, 2014). With respect to the biological activity and desirable
physicochemical, stereochemical, electrochemical, structural and catalytic properties of Schiff base
metal complexes, their values has attracted significant attention and is also relevant for their
application as tools for the analysis of pharmacological constituents (Ejidike P.I et al, 2015).
Chigurupati S. (2015) reported that considering the increased incidences of severe opportunistic
bacterial infections in immunological deficient patients together with the development of resistance
among pathogenic gram positive and gram negative bacteria, there is a great need in finding new
compounds that may be effective against antibiotic resistant bacteria.

Analysis of Common Foods
Nutter Butter Niacin Niacin is found in its natural form in fish, peanuts, yeast, and grains. In the
milling process of grains, it is usually removed. The government's action of trying to reduce niacin
deficiency has led to the fortification of niacin in food. Fortification is an attempt to replenish the
niacin lost in food processing. Niacin helps the energy from food reach the cells in the body. It's
important to the health of the live and production of hormones. Partially Hydrogenated cottonseed
oil Partially hydrogenated cottonseed oil is oil that has been pressed from the kernel of the cotton
seed. The oil then goes through the process of adding more hydrogen to the oil. Adding more
hydrogen makes the oil have a higher boiling point and also helps to increase the shelf life of the oil.
It is used for mayonnaise, salad dressing, shortening, and margarine for its neutral flavor and flavor
stability. The oil is very high in saturated fat. Soy lecithin Soy lecithin is a natural stabilizer for
emulsifying fats in processed foods. It is known to create a creamy texture in wet and dry blends and
in dressings by solidifying the margarine or fat in the food. Lecithin is a group of yellow–brown
fatty acids that come from plant and animals sources, which contains many important nutrients. Its
fat properties are why it is used in various processed foods. Vanillin Vanillin is a natural part of

filtration the solution stayed clear. After roto vap, solution was a milky brown color. IR spec data
showed a weak OH peak as well as strong C–O stretches around 1200 cm–1. V. Discussion
Questions: 1. Our percent yield for alcohol was 84.2% which is average. We rushed through our
vacuum filtration and probably did not let the solid dry long enough and might have not transferred
all of the solid to the vacuum filtration from the beaker. 2. The TLC results showed two different
spots that traveled different distances on the TLC plate, one for ethyl vanillin and one for ethyl
vanillin alcohol which proves there is no evidence of the starting material in our final product. The
product (ethyl vanillin alcohol) was more polar and interacted more with the solvent than our
starting material (ethyl vanillin). This increase in polarity is due to the extra alcohol group in the
ethyl vanillin alcohol and the smaller Rf value also indicates it is more polar and pure than the ethyl
vanillin. 3. The IR spectrum of the starting material shows a medium/strong C–O bond at around
1500cm–1, also the starting material shows a strong C–H bond at around 3000cm–1 and another

What Does Wood Aging Do To Wine
BARRELS
What does wood aging do to a wine? There are three aspects to consider, the wood it is made from,
the size and shape of the cask, and the age of the cask. Oak is the preferred timber because of its
strength and relative lightness, its cellular structure and it is the taste components it contributes to
wine.
Aging wine in small oak barrels accomplishes several things. Barrels add oak nuances and flavors,
similar to the spicing in a food dish. Thus, the choice of a barrel is very important relative to size,
source, degree of toasting, and the cooper's barrel–making technique. There needs to be a synergistic
effect between the wood and the wine.
The major factor influencing the flavor/aroma composition of oak cooperage is the heating and
toasting of the staves during barrel–making. Toasting penetrates about halfway into the stave, about
10–14 mm. ... Show more content on Helpwriting.net ...
But more importantly, it provides the optimum surface area of oak to wine. Smaller casks provide
more oak–contact, but are not cost effective. Lastly, the age of the cask is an important factor. New
oak contains the most flavoring compounds. As the cask is used, tannins and other substances are
leached out of the wood and tartrate crystals from the wine build up on the barrel's interior,
eventually causing the cask to become inert. New oak also allows for more oxidation and inserts
more tannin. It also contains more softening substances from the cellulose of the wood. The best
French barrels cost about $800 each, the American oak costing about half. One barrel holds enough
wine for about 25 cases. Well–treated barrels can be used several times, especially for whites.
Therefore, if a winemaker decides to use a French oak barrel three times, each case of wine will cost
roughly $14 more to produce or $7 more a case with American

What Are The Five Senses
All vertebrates possess five senses of sight, hearing, smell, taste and touch through which they can
experience and make sense of world. Without our senses, we wouldn't have any idea what was going
on around us and the human body would be functionally useless. Each of the senses therefore
provides important functions and serves an intended purpose. The sense of smell is a chemical
sense. It is called chemical sense as it detects the chemicals in the environment and it works on
larger distances. The sense of smell is a primal sense for humans as well as animals. From an
evolutionary standpoint, it is one of the most ancient of senses. Smell (or Olfaction) allows
vertebrates and other organisms with olfactory receptors to identify food, mates, predators, and
provides both sensual pleasure (the odor of flowers and perfume) as well as warnings of danger
(e.g., spoiled food, chemical dangers). For both humans and animals, it is one of the important
means by which our environment communicates with us (John & Leffingwell, 1994)

An odorant acts on more than one receptor, but does so to varying degrees. Similarly, a single
receptor interacts with more than one different odorant, though also to varying degrees. Therefore,
each odorant has its own pattern of activity, which is set up in the sensory neurons. This pattern of
activity is then sent to the olfactory bulb, where other neurons are activated to form a spatial map of
the odor. Neural activity created by this stimulation passes to the primary olfactory cortex at the
back of the underside, or orbital, part of the frontal lobe. Olfactory information then passes to
adjacent parts of the orbital cortex, where the combination of odor and taste information helps create

technique that could be used to detect the presence of marijuana is the Duquenois test, in which 0.5
mL acetaldehyde, 1.0 g vanillin, and 50 mL ethanol are added to a sample and shaken. Extracting
this with chloroform will result in a purple or dark–blue color if marijuana is present. The unknown
contained silver, as both the unknown and silver solutions turned red and formed red precipitates
with the addition of potassium chromate. With the addition of Dithizone, both the unknown and
silver formed colloidal solutions with gray particles, so the unknown was likely silver. Discussion

In doing so, we found that the unknown must contain silver ions, which formed a red precipitate
when potassium chromate was added. Both also formed a colloid with gray particles when
Dithizone was added. Lessons learned Our examination of marijuana and LSD reaffirmed the
information from the reading regarding their characteristics. The calcium carbonate crystals at the
base of marijuana leaf hairs reacted the HCl to produce CO2 (g), as most carbonates will form CO2
(g) when acids are added. The glowing LSD confirmed that hallucinogens have a tendency to glow
under ultraviolet light. Part II demonstrated the solubility rules and ion colors, as seen by AgCl and
PbCl, which both precipitated in our experiment. Sources of

Ciocalteu Reagetion Lab Report
Antioxidative activity can be tested using total phenolic content (TPC), 2, 2–diphenyl–1–
picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) tests. In TPC test, Folin–
Ciocalteu reagent (mixture of phosphomolybdate and phosphotungstate) is used to determine the
antioxidant potential of phenolic and polyphenolic from the sample. DPPH bonds with hydrogen
atom from sample while hydrogen peroxide (H2O2) bonds with iron ion (Fe3+) to form iron (III)
thiocyanate, Fe(SCN)3 in the FRAP test. The phenolic acids and flavonoids are contributing to
antioxidant activities. Radical scavenging activity of petroleum ether extracts of C. nutans was 82.00
± 0.02 % (Arullappan et al., 2014, pp. 1455–1461). Chloroform leaves extract of C. nutans ... Show

Extraction of plant material
Method of Hassan et al. (2015) was adopted for preparation of plant material and extract with minor
modifications. The 70% acetone (Merck, Germany) extracts were prepared by dissolving fine
powder of C. nutans in 1:10 solvent using ultrasonic extraction in an ultrasonic bath for an hour.
Then the extracts were filtered with the aid of a Bucker funnel and Whatman filter paper #1. The
extracts were preserved in airtight bottles at –40°C for further use.
Preliminary qualitative phytochemical analysis
Qualitative phytochemical screening of the extracts was performed using a standard procedure by
Sofowora (1993), Harborne (1984, pp. 4–16) and Trease and Evans (2002, pp. 23–67).
1. Test for alkaloids
A 2 mL of potassium iodide was added to crude extract, which forms brown precipitate with
alkaloids solutions.
2. Test for flavonoids
A 2 mL of sodium hydroxide solution (2%) was added to crude extract, followed by few drops of
diluted acid. Transformation from intense red–orange color to colorless indicated the presence of
flavonoids.
3. Test for glycosides
A 2 mL of glacial acetic acid (1 – 2 drops of 2% ferric chloride) was mixed with crude extract. Then,
the mixture was poured carefully into test tube with 2 mL of concentrated sulfuric acid. Presence of
cardiac glycosides was determined by the

Hershey 's Way Of Making Chocolate
Chocolate is one of the most popular products consumed in the United States and all around the
world. Hershey Chocolate Company originated in 1894, by Milton Hershey (Hershey Company,
2015). He was the first American who began producing milk chocolate bars, and eventually created
multiple flavors that changed the chocolate industry forever. With such mass production and
success, Hershey was able to make milk chocolate, a once luxury item for the wealthy, into an
affordable treat for all (Hershey Company, 2015). Hershey's way of making chocolate is one of a
kind. Hershey starts the chocolate making process by importing cocoa beans from cacao trees found
in tropical regions near the equator. Cacao is ultimately the key ingredient in chocolate. The seeds
from the cacao trees are then harvested and fermented, where they begin to darken and receive their
rich cocoa flavor. The cocoa beans are then sent to the Pennsylvania in the United States, where they
are cleaned, sorted and sent to the roasters. Roasting the cocoa beans at 400–500 degrees brings out
the flavor of the cocoa beans and also dries them out to retrieve the nib. The nib is the most
important part because it is the part that actually makes the chocolate. The nibs are then milled to
create chocolate liquor. Chocolate liquor contains a lot of cocoa butter and will be squeezed out in
liquor presses to create cocoa powder. Additionally, Hershey's chocolate would not be the same
without their use of fresh,

  • 1. Nt1310 Unit 6 Lab Report The purpose of lab 1 was to purify the vanillin (individually) as well as an unknown (with a partner). By recrystallizing both compounds, students were able to determine the percent recovery of each solid and get one step closer to determining our unknown compound. For lab 2, the purpose was to determine the percent recovery both solids (vanillin and the unknown) as well as determining the melting point ranges. By determining the melting point ranges, we would be able to identify our unknown. For the first lab, students worked individually to purify vanillin, but worked in pairs in order to purify an unknown. We began the process of purifying vanillin by weighing it out and dissolved in water, afterwards we placed the solution in an ice bath. After a minutes, we vacuumed out the vanillin, in order to obtain the crystals. In general, recrystallization is used to purify compounds–which was the purpose of this la . As for the unknown solid, a similar process was conducted. However, for the unknown, students had to determine the right solvent in which the unknown would dissolve in and be used for the ...

  • 2. Microorganisms In Environment The risk assessment associated with e.g. detecting microorganisms in the environment and methods for monitoring microbe concentration could pose a challenge as compared to genetically modified (GM) crops (SACGM., 2015). This is because microbial reproduction and their capability for survival in wide environmental conditions is not yet studied thus, possible risks remain unknown especially once released into the environment. One would design experiments to close the knowledge gap e.g. in behaviour and the fate of microbes in the environment though it is currently a big challenge. Despite challenges in knowledge gap, conducting and designing experiments in containment is vital in acquiring sufficient data to inform synthetic biology ... Show more content on Helpwriting.net ... Risk assessment of genetically modified microbes for deliberate release in feed and food applications has not been approved however, there are other applications where similar methods have not hindered innovation (Jörg Ettenauer et al, 2015). An example is the use of novel applications such as the production of animal and human vaccines and gene therapy. It is possible that the acquired experience from the use of such methods could be applied to inform and encourage similar approaches to food and feed applications. There is however a regulatory mechanism in place where if the microbes are deemed safe, Companies can obtain an exemption from the contained use directive (Jörg Ettenauer et al, 2015). Whether that can apply to food and feed applications is not yet clear. An example is where an application applied for an exemption for a bacterial biosensor (E coli), to detect arsenic in ground water (Jörg Ettenauer et al, 2015). On detecting arsenic levels in ground water, the biosensor is engineered to turn green for safe levels or violet for dangerous levels, all under World Health Organisation (WHO) standards (Jörg Ettenauer et al, 2015). 5.

Introduction: Given five samples of a known ketone derivative, the purpose of this experiment is to identify which unknown ketone derivative corresponds to the five known samples. In other words, using specific methods of compound detection, it is possible to match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment, identification of the unknown ketone is accomplished through thin layer chromatography, melting point, and 1H–NMR spectroscopy. The unknown ketone is from a homologous series of methyl ketones. CH3CO (CH2) nCH3 The first step in the lab is the preparation of the solvent used in the developing chamber for thin ... Show more content on Helpwriting.net ... As mentioned in the introduction, a sample of the unknown is placed in the spectrometer, more specifically, in the midst of a magnetic field.[1] To conclude, it is evident from the Rf values obtained that unknown # 3 Rf is closest to that of 2 – Octanone. With a 7.2 % error, this can be due to the reagent being diluted with too much ethanol or still containing traces of the acid, however if traces of the acid are present then the melting point[3] should be significantly lower. From the melting points we can determine that unknown # 3's melting point is closest to that of 2 – Octanone with an 8.6% error. This can be attributed by either the unknown being diluted with too much ethanol and water or the mixture containing traces of acid. However, as aforementioned, traces of acid would only lower the melting point not raise it, therefore it is unlikely that traces of acid can be attributed to the error.[3] From the H NMR spectrum, integration suggests that at 1.9 and 2.25 there is some indication of possible ketone fragments. 1H–NMR Spectra for 2–octanone: [5] 2– Octanone's structure contains a hydrocarbon chain therefore the spectrum has indicated the presence of methyl groups giving further evidence that the unknown is in fact 2–Octanone.

  • 8. TLC Analysis And Synthesis Of Cinnamic Acid The recrystallized cinnamic acid was obtained from the previous lab. It was a white and flaky powder and had a very slight sweet/spicy smell. When weighed, the recrystallized cinnamic acid was only .340 g. The starting amount was .500 g, so the percent recovery was 68.0%. ((.34g/.50g) x 100%)). The low percent recovery may have been due to the addition of too much solvent(book). Last lab, 90.0 mL of solvent was used to dissolve the cinnamic acid, which was the maximum amount directed by the instructor. The melting point range was analyzed to be 128.5 C– 131 C.

  • 9. Pros And Cons Of Bruichladdich Bruichladdich is no stranger to No Age Statement whisky. In fact over the past ten or twelve years they've probably been one of the most visible proponents of the concept. I think this approach was first viewed by the distillery as a necessary maneuver in order to get whisky on the shelves throughout the first decade of production after their 2001 reopening. Considering how fundamentally opposed I am to the idea of opaque marketing with whisky, I imagine it's somewhat surprising (even to myself, if I'm to be honest) how much I adore and support Bruichladdich. Let's face it...no other distillery has done as much to reinvigorate the whisky world over the last few years as Bruichladdich. They've pushed hard for higher bottling strengths – first 46% as a standard, and now 50%. They've foregone artificial colouring. They've made a mockery of the concept of chill–filtration. Their employment of local labour is staggering, especially viewed in contrast to the two–man crews running some of Diageo's multi–million litre producers.

Nutella Makes Up for Cocoa Shortage During World War II The period was World War II there was a shortage of cocoa at the time; Mr. Pietro Ferrero, a pastry maker founder of the Ferrero company thought that using hazelnuts and mixing it with skim milk and a little of chocolate would be a good way to appease the short supply of cocoa by allowing chocolate to last longer. This still being the product's two main ingredients today; hazelnut and cocoa. In Italy, during the 1940s; Mr. Ferrero created the Nutella spread. In its earliest form, Nutella a hazel nut and chocolate spread was originally called "pasta Gianduja" this of course was the Italian term, "pasta" means paste and the "Gianduja" was the name of a famous character in the region in Italy. The paste was first introduced by being made in the loaves of bread wrapped in tinfoil, used to make sandwiches. A product popular to children, the bread was tossed away and the paste was most favored. Later workers decided it would be best if the spread was made easier to spread on the bread then being known as "Supercrema Gianduja", thus being processed in large jars with a yellow sticker on the middle and a red lid. Soon after in 1964 "Pasta Gianduja" or "Supercrema Gianduja" the product was named Nutella: "nut" being the origin of the product and "ella" a soft Italian term.

Once the final product had been recrystallized with isopropanol, the crystal were collected via vacuum filtration. These crystals took some time to dry out, but they eventually were dry enough to scrape out for further evaluation. After an IR was run, it was quite obvious the product was surely Iodovanillin. Further analysis of the melting point was taken to ensure the final product was the desired Iodovanillin. A few sources of potential error are as follows: loss of product on glassware throughout the experiment, inadequate measuring of chemicals, "impure" chemicals being worked with, and loss of final product during crystallization processes.

  • 17. Lab Analysis Of Horseradish Peroxidase Type 1 Horseradish peroxidase Type 1 was used in this laboratory experiment, it was an enzyme that helped catalyze the oxidative coupling of vanillin to produce divanillin. The role of the enzyme is to increase the rate of the overall chemical reaction to reduce reaction time, therefore making the reaction process faster. The Horseradish peroxidase Type 1 achieved this by decreasing the activation energy required for a chemical to react, thus allowing the reaction to process through a lower activation energy, which increases the reaction rate and makes the reaction faster. Reaction: In this experiment, the change of pH was also a key step of the reaction because the pH factors in the stability of an enzyme. Since we used an enzyme in this reaction, the pH levels of the solution needed to change first before adding the Horseradish peroxidase Type 1. The reason for changing the pH levels is to ensure that the enzyme will work during the reaction and having a high or extreme pH causes the denature an enzyme. After 0.50 grams of Vanillin were dissolved in Deionized water, we added 0.1 M acetic acid for the pH levels to drop until the pH was 4 which was the desired pH level.

Evolva acknowledges that the public does not welcome the use of synthetic biology or GM products due to little or no public awareness for such products, but there are other means of overcoming such challenges. One example is when the company asked for permission to label synthetic biology produced vanillin as "natural" since the product is produced through a natural fermentation process, just like alcohol fermentation process.

The origins and reactions make coffee flavour a complexity science to study and also explain why coffees exhibit such diverse, unique and specific flavours. (Sunarharum et al., 2004) Sunarharum et al. (2004) summarised that coffee volatiles compounds consist of a wide range of chemical class like hydrocarbons, alcohols, aldehydes, ketones, carboxylic acids, ester, pyrazines, sulphur compounds, furans, phenols among others. Furans are one of the aroma active compound quantitatively high which show significant concentration found in roasted coffee and brew coffee beverage. Furans are usually formed through thermal degradation of carbohydrates, ascorbic acid or unsaturated fatty acid during roasting. The volatile exhibit malty and sweet roasted aroma with a relatively high sensory threshold but due to their high concentration, furans still show importance in coffee aroma. (Flament, 2002) Roasting coffee beans also produced furanones, mainly by Maillard reaction and other side reaction.

(2012) – This work is focused on the development of novel carbohydrate– acetonitrile–based ATPS and on the evaluation of the carbohydrate structure through the phase separation ability. For that purpose, various carbohydrates were investigated, namely monosaccharides (glucose, mannose, galactose, xylose, arabinose, and fructose) and disaccharides (sucrose and mannose). Moreover, commercial sucrose, fructose and glucose commonly used in the food industry were also tested. The ternary phase diagrams were determined at 298 K, and the respective binodal curves, tie–lines and tie–line lengths are reported. Finally, to appraise on the extractive potential of the proposed ATPS, the partitioning of a common antioxidant, vanillin, was additionally investigated. Freire et al.

Lab Report Of Vanillin CHAPTER 1 INTRODUCTION 1.1 Background and Problem Statement 1.1.1 Schiff Base The condensation product of primary amines with active carbonyl compounds have resulted in the formation of Schiff base compound. This has been reported by Hugo Schiff in 1864. Schiff base compound contain azomethine –C≡N with a general formula RHC=N–R' where R and R' are alkyl, aryl, cyclo alkyl or heterocyclic groups which may be variously substituted. These compounds are also known as anils, imines or azomethines (Mishra N. et al, 2013). Structurally, a Schiff base is a nitrogen analogue of an aldehyde or ketone in which the carbonyl group (C=O) has been replaced by an imine or azomethine group (Figure 1.1) (Abu–Dief M.A et al, 2015).

  • 31. Analysis of Common Foods Nutter Butter Niacin Niacin is found in its natural form in fish, peanuts, yeast, and grains. In the milling process of grains, it is usually removed. The government's action of trying to reduce niacin deficiency has led to the fortification of niacin in food. Fortification is an attempt to replenish the niacin lost in food processing. Niacin helps the energy from food reach the cells in the body. It's important to the health of the live and production of hormones. Partially Hydrogenated cottonseed oil Partially hydrogenated cottonseed oil is oil that has been pressed from the kernel of the cotton seed. The oil then goes through the process of adding more hydrogen to the oil. Adding more hydrogen makes the oil have a higher boiling point and also helps to increase the shelf life of the oil. It is used for mayonnaise, salad dressing, shortening, and margarine for its neutral flavor and flavor stability. The oil is very high in saturated fat. Soy lecithin Soy lecithin is a natural stabilizer for emulsifying fats in processed foods. It is known to create a creamy texture in wet and dry blends and in dressings by solidifying the margarine or fat in the food. Lecithin is a group of yellow–brown fatty acids that come from plant and animals sources, which contains many important nutrients. Its fat properties are why it is used in various processed foods.

After roto vap, solution was a milky brown color. IR spec data showed a weak OH peak as well as strong C–O stretches around 1200 cm–1. V. Discussion Questions: 1. Our percent yield for alcohol was 84.2% which is average. We rushed through our vacuum filtration and probably did not let the solid dry long enough and might have not transferred all of the solid to the vacuum filtration from the beaker. 2. The TLC results showed two different spots that traveled different distances on the TLC plate, one for ethyl vanillin and one for ethyl vanillin alcohol which proves there is no evidence of the starting material in our final product. The product (ethyl vanillin alcohol) was more polar and interacted more with the solvent than our starting material (ethyl vanillin). This increase in polarity is due to the extra alcohol group in the ethyl vanillin alcohol and the smaller Rf value also indicates it is more polar and pure than the ethyl vanillin. 3. The IR spectrum of the starting material shows a medium/strong C–O bond at around 1500cm–1, also the starting material shows a strong C–H bond at around 3000cm–1 and another medium C–H bond at 2865cm–1 indicating an aldehyde group whereas the product does not.

  • 36. What Does Wood Aging Do To Wine BARRELS What does wood aging do to a wine? There are three aspects to consider, the wood it is made from, the size and shape of the cask, and the age of the cask. Oak is the preferred timber because of its strength and relative lightness, its cellular structure and it is the taste components it contributes to wine. Aging wine in small oak barrels accomplishes several things. Barrels add oak nuances and flavors, similar to the spicing in a food dish. Thus, the choice of a barrel is very important relative to size, source, degree of toasting, and the cooper's barrel–making technique. There needs to be a synergistic effect between the wood and the wine. The major factor influencing the flavor/aroma composition of oak cooperage is the heating and toasting of the staves during barrel–making. Toasting penetrates about halfway into the stave, about 10–14 mm. ... Show more content on Helpwriting.net ... But more importantly, it provides the optimum surface area of oak to wine. Smaller casks provide more oak–contact, but are not cost effective. Lastly, the age of the cask is an important factor. New oak contains the most flavoring compounds. As the cask is used, tannins and other substances are leached out of the wood and tartrate crystals from the wine build up on the barrel's interior, eventually causing the cask to become inert. New oak also allows for more oxidation and inserts more tannin. It also contains more softening substances from the cellulose of the wood. The best French barrels cost about $800 each, the American oak costing about half. One barrel holds enough wine for about 25 cases. Well–treated barrels can be used several times, especially for whites. Therefore, if a winemaker decides to use a French oak barrel three times, each case of wine will cost roughly $14 more to produce or $7 more a case with American ... Get more on HelpWriting.net ...

  • 38. What Are The Five Senses All vertebrates possess five senses of sight, hearing, smell, taste and touch through which they can experience and make sense of world. Without our senses, we wouldn't have any idea what was going on around us and the human body would be functionally useless. Each of the senses therefore provides important functions and serves an intended purpose. The sense of smell is a chemical sense. It is called chemical sense as it detects the chemicals in the environment and it works on larger distances. The sense of smell is a primal sense for humans as well as animals. From an evolutionary standpoint, it is one of the most ancient of senses. Smell (or Olfaction) allows vertebrates and other organisms with olfactory receptors to identify food, mates, predators, and provides both sensual pleasure (the odor of flowers and perfume) as well as warnings of danger (e.g., spoiled food, chemical dangers). For both humans and animals, it is one of the important means by which our environment communicates with us (John & Leffingwell, 1994) Smells are the perception of chemicals in the air or in our food.

Similarly, a single receptor interacts with more than one different odorant, though also to varying degrees. Therefore, each odorant has its own pattern of activity, which is set up in the sensory neurons. This pattern of activity is then sent to the olfactory bulb, where other neurons are activated to form a spatial map of the odor. Neural activity created by this stimulation passes to the primary olfactory cortex at the back of the underside, or orbital, part of the frontal lobe. Olfactory information then passes to adjacent parts of the orbital cortex, where the combination of odor and taste information helps create the perception of flavor. (Brain facts ...

  • 43. Hershey 's Way Of Making Chocolate Chocolate is one of the most popular products consumed in the United States and all around the world. Hershey Chocolate Company originated in 1894, by Milton Hershey (Hershey Company, 2015). He was the first American who began producing milk chocolate bars, and eventually created multiple flavors that changed the chocolate industry forever. With such mass production and success, Hershey was able to make milk chocolate, a once luxury item for the wealthy, into an affordable treat for all (Hershey Company, 2015). Hershey's way of making chocolate is one of a kind. Hershey starts the chocolate making process by importing cocoa beans from cacao trees found in tropical regions near the equator. Cacao is ultimately the key ingredient in chocolate. The seeds from the cacao trees are then harvested and fermented, where they begin to darken and receive their rich cocoa flavor. The cocoa beans are then sent to the Pennsylvania in the United States, where they are cleaned, sorted and sent to the roasters. Roasting the cocoa beans at 400–500 degrees brings out the flavor of the cocoa beans and also dries them out to retrieve the nib. The nib is the most important part because it is the part that actually makes the chocolate. The nibs are then milled to create chocolate liquor. Chocolate liquor contains a lot of cocoa butter and will be squeezed out in liquor presses to create cocoa powder.
