Food additives are used to preserve foods and improve qualities like taste, but some can be harmful to health. Common harmful additives include sodium nitrite and nitrate used in processed meats which are linked to cancer, and artificial sweeteners aspartame and acesulfame K that may cause neurological and behavioral issues. Flavor enhancers like monosodium glutamate and preservatives like BHA/BHT have also been linked to conditions like headaches, hyperactivity, and cancer.

Types of adulteration
Common food adulteration
Legislation regarding control of food adulteration
Substances which are of little or no nutritive value, but are used in the processing or storage of foods or animal feed, especially in the developed countries; includes antioxidants; food preservatives; food coloring agents; flavoring agents; anti-infective agents; vehicles; excipients and other similarly used substances. Many of the same substances are pharmaceutics aids when added to pharmaceuticals rather than to foods. Food additives are substances added to food to preserve flavor or enhance its taste and appearance. Some additives have been used for centuries; for example, preserving food by pickling with vinegar, salting, as with bacon, preserving sweets or using sulfur dioxide as in some wines. With the advent of processed foods in the second half of the 20th century, many more additives have been introduced, of both natural and artificial origin. It is sometimes wrongly thought that food additives are a recent development, but there has certainly been an increase in public interest in the topic. Not all of this has been well-informed, and there are signs that commercial interests have been influenced by consumer pressure, as well as food producers manipulating the situation by marketing techniques. Various labeling regulations have been put into effect to ensure that contents of processed foods are known to consumers, and to ensure that food is fresh-important in unprocessed foods and probably important even if preservatives are used. In addition, we also need to add some preservatives in order to prevent the food from spoiling. Direct additives are intentionally added to foods for a particular purpose. Indirect additives are added to the food during its processing, packaging and storage. Food Preservatives are the additives that are used to inhibit the growth of bacteria, molds and yeasts in the food. Some of the additives are manufactured from the natural sources such as corn, beet and soybean, while some are artificial, man-made additives. Most people tend to eat the ready-made food available in the market, rather than preparing it at home. Such foods contain some kind of additives and preservatives, so that their quality and flavor is maintained and they are not spoiled by bacteria and yeasts.
Food technology is a branch of food science that addresses the production, preservation, quality control and research and development of food products.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

1. FOOD
ADDITIVES
Dr.J.N.Naidu
Professor &HOD
Department of Biochemistry
2. Why use Additives ?
Food produced on the large scale that is needed to
supply supermarkets and other food shops has to be
transported and stored before it is consumed .
It has to stay in top condition over a much longer
period of time than home cooked food.
Additives are used so that these foods still have a
consistently high quality.
3. What are food additives?
• They are chemicals ,or ingredients which are added
to food products for maintaining their stability.
• Additives are artificial or natural chemicals , added
to food , for microbial and chemical stability of foods
or delay or even stop food rancidity.
4. The Codex Alimentarious Commission has defined
“Food Additive” as under: -
Food Additive means any substance not normally
consumed as a food by itself and not normally used as a
typical ingredient of the food ,whether or not it has nutritive
value, the intentional addition of which to food for a
technological purpose in the manufacture, processing,
preparation, treatment , packing, or holding of such food
results, or may be reasonably expected to result in it or its
bye products becoming a component or otherwise
affecting the characteristics of such foods.
The term does not include contaminants or substances
added to food for maintaining or improving its nutritive value.
5. Functions of food additives:
• Improve the taste or appearance of a processed food
Eg: beeswax –glazing agent is used to coat apples
• Improve the keeping quality or stability of a food
Eg: sorbitol –added to mixed dried fruit to maintain
moisture level and softness of the fruit
6. Functions of food additives:
• Improve shelf life or storage time
Eg: sulphurdioxide added to sausage meat to avoid
microbial growth
• Ensure nutritional value
• Maintain uniform quality and to enhance quality
parameters like flavour,colour etc., in large scale
production
7. Types of food additives:
Direct or intentional food additives which are
added deliberately to improve its sensory quality,
stability, ease in processing and retention of quality
during handling and retailing .
Indirect or unintentional food additives which get
included into foods incidentally during handling,
processing and packaging.
8. Classes of food additives
Preservatives.
Food colours.
Food flavors and flavor enhancers
High intensity / lowcalorie sweeteners.
Antioxidants.
Emulsifiers.
Acidulants
Anti-caking agents
9. E-Codes
• E-codes are codes sometimes found on food labels
in the European Union (Great Britain, France,
Germany, Spain, Italy, Portugal etc.)
• The codes indicates an ingredient which is some
type of food additives
• The “E” indicates that is a “European Union
Approved” food additive
• Other countries have different food labeling laws
10. E-Codes number Groups of Food Ingredients
E-100 Coloring agents
E-200 Preservatives
E-300 Anti-oxidants
E-400 Thickeners, Stabilizers,
Gelling agents, Emulsifiers
E-500 Agents for physical
characteristics
E-600 Flavor enhancers
11. What is JECFA?
The Joint FAO/WHO Expert Committee on Food
Additives (JECFA) is an international scientific expert
committee that is administered jointly by the Food and
Agriculture Organization of the United Nations (FAO)
and the World Health Organization (WHO).
It has been meeting since 1956, initially to evaluate
the safety of food additives.
Its work now also includes the evaluation of
contaminants, naturally occurring toxicants and
residues of veterinary drugs in food.
12. JECFA
The Committee also develops principles for the
safety assessment of chemicals in food that are
consistent with current thinking on risk
assessment and take account of recent
developments in toxicology and other relevant
sciences.
14. For the benefit of consumers , the Codex Alimentarius
Commission has prepared the INS for food additives ,
which provides an agreed international numbering
system for identifying food additives
15. FAO/WHO Codex Alimentarius Commission
Founded in 1963 by a joint initiative of the FAO and the
WHO, the Codex Alimentarius Commission
Formulates and harmonizes food standards and
ensures global implementation
Develops food standards, guidelines, and related texts
such as codes of practice under the Joint FAO/WHO Food
Standards Programme
Generates guidelines to protect the health of consumers
and ensures fair trade practices in food trade, and
Promotes coordination of all food standards work
undertaken by international governmental and non-
governmental organizations
16. What are the effects of food additives?
Immediate effects:
Headache
Change in energy level
Alterations in mental concentration, behavoiur , or
immune response
Long term effects:
Increase risk of cancer ,cardiovascular disease and
other degenerative conditions
17.
18. Preservatives:
• They prevent spoilage of food due to fungi , bacteria
and other microorganisms
• Commonly used in
Low fat spreads
Cheeses, margarine, mayonnaise
Bakery products
Dried fruit preparations
Eg: sodium benzoate , sodium nitrite, benzoic acid
,BHA(butylated hydroxy anisole ) /BHT(butylated
hydroxy toluene)
19. Sodium benzoate- carbonated drinks ,pickles ,
sauces
Side effects:
aggravates asthma and suspected to be a
neurotoxin and carcinogen , may cause fetal
abnormalities .
Worsens hyperactivity
20. Sodium nitrite and nitrate – sausages, hotdogs,
smoked fish, canned meats
Side effects:
Nitrite is a Carcinogen (prostate, breast and
stomach cancer in humans)
Nitrate -Increases risk of miscarriages , fetal deaths
and birth defects in lab. animals
21. Benzoic acid – drinks, low sugar products,
cereals , meat products
Side effects:
May temporarily inhibit digestive enzyme function .
May deplete GLYCINE levels . AVOID in
asthma ,or allergies
22. BHA/BHT – potato chips , vegetable oils ,
chewing gum
(butylated hydroxy anisole/toluene)
Side effects:
May be carcinogenic to humans .
BHA also interacts with nitrites to
form chemicals known to cause
changes in the DNA of cells.
Toxic to CNS and liver.
23. Colour additives:
Make the food look appealing and so, taste better
These are described as one of the most
dangerous additives .
Synthetic colours are made from coaltar or
petroleum
24. Colour Additives
Used to colour beverages, dessert
powders, icecreams, custards
Cause allergies ,asthma , hyperactivity
Eg: erythrosine, allura red,tartrazine ,

29. Flavor enhancers:
Taste is a complex mixture of flavors and aroma .
Flavourings are added to food products to give or
intensify flavour.
Eg: monosodium glutamate – is the sodium salt of the
aminoacid glutamic acid and a form of glutamate
31. Monosodium glutamate:
Side effects :
headache , weakness, nausea , altered heart rate,a
burning sensation in the forearms and back of the
neck ,tightness in the chest.
Neoantal exposure is linked to stunted growth and
obesity – due to reduction in release of GH.
32. Sweeteners:
( nonnutritive or alternative sweeteners):
Substances that impart sweetness to food but supply
little or no energy to the body
Functions :
• Provide texture in baked foods
• Humectant in cakes
• Lowers the freezing point in icecream

jellies),Yoghurt
35. Side effects of sweeteners :
behavioural problems,
hyperactivity ,
allergies and
possibly carcinogenic
Advantage :
They allow diabetics to have sugar free but
sweet tasting food.
36. Antioxidants :
Oxidation is a destructive process , causing loss of
nutritional value and changes in chemical
composition
Antioxidants are added to food to slow the rate of
oxidation and if used properly can extend the shelf life
of food in which they have been used.
Eg: BHA( butylated hydroxy anisole) , BHT(butylated
hydroxy toulene)
38. Antioxidants :
Side effects:
• Hyperactivity ,
• Asthma ,
• Angiodema,

• May affect ESTROGEN levels .
• Have been linked with cancer in animals
39. Emulsifiers:
Emulsions in food are mixtures of oil and water.
Emulsifier keeps the mixture stable and prevents the
oil and water from seperating into two layers.
Other Functions:
• Make food appealing
• Effect on the texture of food
• Prevent the growth of moulds in low fat spreads
• Aid in processing and help maintain quality and
freshness
40. Examples of food emulsifiers are:
Egg yolk (in which the main emulsifying agent is lecithin)
Proteins and low-molecular-weight emulsifiers are common
as well
Soy lecithin is another emulsifier and thickener
In some cases, particles can stabilize emulsions through a
mechanism called Pickering stabilization

•Peanut butter
•Icecream
•Coffee whiteners
•Margarine/low fat spreads
•Biscuits and toffees
•Cakes
•Frozen desserts
•Bread
•Chewing gum
43. Acidulants:
They are additives that give
a sharp taste to foods.
Also assist in the setting of gels
and to act as preservative
The acid environment they produce prevents the growth of
microbes
Eg: widely used organic acid is citric acid in food products ,
drinks and pharmaceuticals
44. Anticaking agents:
Processed food often contains ingredients that are
mixed as powders.
anti-caking agents are added to allow them to flow
and mix evenly during the food production process.
Eg: silicon dioxide ,calcium silicate
Table salt
45. Anti-caking agents:
Commonly found in
• vending machine powders( coffee , cocoa )
• Milk and cream powders
• Grated cheese

Keep meat that bright red colour and help prevent
bacterial growth
49. Sodium nitrite and nitrate:
Side effects : nausea , dizziness , headache ,vomiting
• Studies confirm that nitrites and nitrates can cause
prosatate,breast,gastric cancer in humans
•Link to cancer – nitrites can lead to formation of
chemicals called NITROSAMINES in the digestive tract
which may cause cancer.
•Nitrates are associated with increased miscarriages, fetal
deaths , and birth defects in laboratory animals.

excitatory neurotransmitters ,catecholamines that
energise you and speed up body function
Aspartic acid -- an excitotoxin i.e, it overstimulates
nervous system
Methanol – it is metabolised to formaldehyde which is
“ known human carcinogen”
CAUTION: Phenylketonuric patients must exclude
aspartame in their diet ; also pregnant women must
exclude.
53. Acesulfame K :

disengage the “I’m full” function which explains
effects of weight gain
56. Monosodium glutamate:
Caution:danger
Pregnant women who ingest
this are at increased risk of
developing fetus with smaller pituitary,
thyroid ,ovary/testis that leads to reproductive
dysfunction
Neonatal exposure has been linked to stunted
growth and obesity as there is reduction in the release
of Growth hormone.
57. BHT and BHA:
Antioxidant and preservative.

64. Colour additives :
Dangerous additives – blue 1 and blue 2, red 3 , green 3 and
yellow 6
Side effects : allergy , asthma, hyperactivity and possible
carcinogen
Link to cancer – cause chromosomal damage
65. Colour additives- link to hyperactivity
In 2008 the European
Food Safety Authority (EFSA)
assessed this study.
They concluded
that the findings may be relevant
for specific individuals showing
sensitivity to food additives.
Since mixtures and not individual
additives were tested in the study,
it is not possible to ascribe the
increased hyperactivity to any
of the individual food additives.
66. Colour additives- link to hyperactivity
In 2007 a group of British scientists
published a study showing that children
who drank a mixture of 4 synthetic
food colours and a food preservative
became more hyperactive than when
they did not drink the mixture.
The level of food colours and
food preservative in the experimental
drink was comparable to the level
that children may drink or eat in real life
if they consume brightly coloured sweets or soft drinks.
67. High fructose corn syrup-H F C S
• Flavour enhancer
• Derived from corn starch , usually a combination of 55%
fructose and 45% 0f sucrose
• Found in softdrinks, baked foods , ketchup

• It also inhibits vitamin absorption from fat soluble
carotenoids that are found in fruits and vegetbales
70. Sodium chloride (table salt):
Flavour enhancer and preservative
During the refining process , naturally occuring
minerals and trace elements are stripped away ,
then it is blasted with high heat ,
bleached and
chemicals like aluminium and anti-caking agents are
added to it.
71. Sodium chloride (table salt):
Side effects :
Too much processed salt intake burdens the
kidneys and adrenals
Depletes calcium and interferes with absorption of
essential nutrients
Causes high BP, heart attack and stroke
“low sodium salt” is more toxic , as chemicals
are added to it to remove sodium and simulate the
synthetic taste of salts
72. •Junk foods
• It doesnot provide our body with the essential
