Yeast is used to make bread and alcoholic beverages. It respires and produces carbon dioxide, which allows dough to rise when yeast is mixed into it. Yeast converts sugars into alcohol and carbon dioxide during fermentation. When making bread, yeast respires the sugars released from starch by amylase enzymes in flour, producing carbon dioxide that becomes trapped in the dough by gluten proteins and causes it to rise in the oven. Fermenters provide controlled conditions like temperature, pH, oxygen, and stirring to support microbial growth for producing biological products through fermentation.
INTRODUCTION:
BREAD is a dietary product obtained from the fermentation and the subsequent baking of a dough mainly made of cereal flour and water, made in many different ways and sometimes enriched with typical regional ingredients.
Ingredients of bread:
Flour is the bulking ingredient of bread, it forms the structure of the product,contains gluten which helps to form an elastic stretchy dough.
Yeast is a raising agent. Yeast produces gases to make the bread rise.
Salt is required to bring out flavour in the bread, it is used in small quantities.Too much of this ingredient will stop the yeast from growing.
Yeast needs energy to grow. Sugar provides the food for the yeast; it is needed to help the yeast grow.
Water is used to bind the flour together and helps to form the structure of the bread.
Fats or oils improve the texture of the bread, preventing it from going stale quickly.
Starter culture:
Baker's yeast is the common name for the strains of yeast commonly used as a leavening agent in baking bread and bakery products, where it converts the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species Saccharomyces cerevisiae, which is the same species (but a different strain) commonly used in alcoholic fermentation which is called brewer's yeast.
Bread Making Process
Mixing has two functions: to evenly distribute the various ingredients and allow the development of a protein (gluten) network to give the best bread possible.
Once the bread is mixed it is then left to rise (ferment).
Any large gas holes that may have formed during rising are released by kneading.
Moulding the dough into desired loaf shape.
During the final rising the loaf fills with more bubbles of gas, and once this has proceeded far enough they are transferred to the oven for baking.
The loaf is then placed in a preheated oven to bake. Such a high heat will kill the yeast, thus stopping its process of rising and growth.
The whole loaf is cooled to about 35°C before slicing and wrapping can occur without damaging the loaf.
Types of Bread
1. White Bread
2. Brown Bread
3. Wholemeal bread
4. Rye bread
Apart from above there are several types like Crisp bread, Flatbread is often simple, made with flour, water, and salt.
Microbial spoilage
Molds are the primary spoilage organisms in baked goods, with Aspergillus, Penicillium, and Eurotium being the most commonly isolated genera.
Quality control
As a foodstuff, bread is subject to stringent government food processing regulations, including, but not limited to the percent of additives allowed, sterilization of plant equipment, and cleanliness of plant workers. In addition to adhering to these regulations, processors control the quality of their products to meet consumer expectations by installing checkpoints are various stages of the processing.

11. How do you know the bread has
risen enough?
Should double in size
Push two fingers into the dough, if the holes
remain but the top stays smooth and satiny.
12. Why is the milk scalded then
cooled?
To destroy enzymes that make dough sticky
To allow yeast to grow at optimum temp.
– Too hot of temperature will kill the yeast!

18. Yeast is used for making alcohol.
Yeast is a single-celled fungus
Yeast cells feed saprophytically. This means they
secrete enzymes from their cells. The enzymes
digest the food on which the yeast is living, breaking
down large molecules into small ones. The small
molecules then diffuse into the yeast cell.
19. 'Wild' yeast grows in many different places. It
usually grows on foods which contain sugar,
such as fruit. When we grow yeast, we need to
provide it with the types of food which it needs. It
is usually grown in a solution containing
carbohydrate - usually in the form of sugar and
minerals, including ammonium ions. Each yeast
cell absorbs the sugar and minerals, and uses
some of them to grow. When the cell gets to a
certain size, it produces a new cell by budding.
Yeast cells reproduce fastest when the tem-
perature is quite warm, around 40 °C.
20. People have been using yeast for thousands of years to
make alcohol. If yeast is added to a sugar solution, it
absorbs some of the sugar into its cells. It then uses this
sugar in respiration.
Usually, the yeast respires anaerobically. When it does this,
it converts the sugar to ethanol (a type of alcohol) and
carbon dioxide. This process is called alcoholic
fermentation. 'Fermentation' is a name for any type of
respiration which makes a product other than carbon dioxide
and water. The equation for alcoholic fermentation is:
Glucose → alcohol + carbon dioxide + energy
21. Many different alcoholic drinks are made in
this way Beer is made by providing the
yeast with the sugar maltose, obtained from
germinating barley seeds. Usually, hops
are added as well, to give a bitter flavour to
the beer. Wine is made by providing the
yeast with sugar from grapes.
22. Yeast is used for making bread.
When yeast respires, it produces carbon dioxide. If this
happens inside a dough made from flour and water, the
bubbles of carbon dioxide get trapped in the dough, and
make it rise. This is how bread is made. The dough is
made using flour made from cereal grains, usually
wheat. The flour contains starch, amy- lase and protein.
23. The starch is the energy source for the yeast.
The amylase digests the starch to sugar, so that
the yeast can absorb it and use it in respiration.
Some bread flours have extra amylase added to
them to speed up this process. The amylase
does not begin acting on the starch until water is
mixed with the flour.
The protein is important for the texture of the
bread. The most important protein in bread flour
(apart from the amylase!) is called gluten. This
forms sticky, threads as the yeast works on the
dough.
24. This helps to trap the bubbles of carbon dioxide, and
makes the dough rise well. Farmers who want to sell
their wheat for bread making choose varieties which are
known to produce grains containing a lot of gluten.
To make bread, yeast, sugar, flour and water are mixed
together to make a dough, which is then left in a warm
place to rise. The dough is then mixed again, and made
into the shapes of the loaves to be made. It is left to rise
again, and then baked. The high tempera- tures kill the
yeast, break down the alcohol which it has made, and
alter the remaining starch and gluten to make a firm
textured bread.

30. Use of enzyme in biological washing powders
Biological washing powders contain protease and lipase to remove protein
stains
and fat/grease from clothes. The enzymes break down proteins or fats on
the fabric,
forming water-soluble substances that can be washed away.
31. Example: Blood contain the red protein Haemoglobin (Hb). The
Proteases in biological washing powder break Hb molecules into
smaller molecules, which are not coloured and which dissolve in water
and can be washed away.
This makes the washing powder more effective than detergent alone,
especially at lower temperatures.
This save energy (no need to boil water), but if the temperature is
too high, the enzyme will be denatured.

36. Fermenter or bioreactor refers to a device that
provides all the basic necessities important for
biological product extraction. A fermenter
contains different devices that help to maintain
the environmental factor inside it which in turn
leads to the production of biological products.
Therefore the main objective of a fermenter is
to maintain a controlled environment that
supports the growth of the bacteria or any
other organism.
37. here are several important factors that need to be accurate
to design a fermenter. Those factors are following
•The vessel should be well equipped to maintain aseptic
conditions inside it for a number of days.
•Aeration and agitation are important for the production of
biological metabolites. However, controlled agitation is
required to prevent any damage to the cells.
•It should be less expensive in terms of power consumption.
•Temperature is an important environmental factor required
for microbial growth. Therefore, a temperature control
system is required.
38. •Optimum pH is important for the growth of the organism;
therefore, the fermenter must be equipped with a pH
controller.
•The fermentation of a huge culture is a time-consuming
process. It needs to be contamination-free until the
process is complete. Apart from that, it is also important
to monitor the growth rate of the organism. Therefore, an
aseptic sampling system is needed to design a fermenter.
39. •The fermenter vessel should be designed properly to
minimize the labor involved in cleaning, harvesting, etc.
•It should be designed in such a way that it reduces
evaporation.
•The vessel needs to be equipped with a smooth
internal surface to support adequate mixing.
