Question

Which of the following practices of biology is a major contribution to the industrial production of dairy products?

• A. Aeration
• B. Fermentation
• C. Genetic engineering
• D. Both B and C

Answer 1

The correct option is D Both B and C

Fermentation is the process in which the anaerobic bacteria convert the sugar into acids or alcohol. This is the main process which is involved in the production of the dairy products. The lactic acid bacteria are present in the milk which allows fermentation of the milk to produce cheese, curd, buttermilk, etc. The process of genetic engineering is used for the manipulation of the bacteria to increase the efficiency and produce more quantities of the product. These two processes of biology have helped in the industrial production of large quantities of dairy products.

Thus, the correct answer is option D.
