Answer
There
is wide range of applications in industry, especially in the food industry. For
example, baking breads, manufacture beer, wine and alcoholic beverages, dairy
product and ethanol. In the baking breads, yeast is needed to mix with flour.
The carbon dioxide gas produced from the fermentation process enable the dough
to rise and soften the breads when it is baked in the oven.
During
the making of the dairy products such as yoghurt, the enzyme from bacteria acts
on milk sugar (lactose) to produce lactic acid. The lactic acid can give the
milk a sour taste and make milk into curd called yoghurt. In order to produce a
variety of yoghurt which is different tastes and flavour can be added with various flavours like strawberry and
blueberry.
The
enzyme diastase in the malt derived from cereals or fruit juices can be
manufactured beer, wine and alcoholic
beverages.
The enzyme diastase converts starch and other sugars into maltose. Yeast is then
added to allow fermentation to take place. During this process, the maltase
converts the maltose into glucose. Glucose is converted into ethanol and carbon
dioxide by the enzyme zymase. The fermented mixture is
then distilled to produce beer or wine depends on ethanol
concentrations.
Ethanol
can be obtained from the alcoholic fermentation. Ethanol acts as a solvent which
used in the pharmaceutical industry. Ethanol can also manufacture various
organic compounds such as acetic acid in vinegar.
