Question

Which of the following biological techniques helps in the preservation of food?

• A. Vaccination
• B. Pasteurization
• C. Artificial insemination
• D. None of the above

Answer 1

The correct option is B Pasteurization

Pasteurization is the method in which heat treatment is provided for the preservation of milk products. The milk is boiled or heated to a temperature of about 62${}^o$ C which kills all the bacteria and other microbes. This helps to preserve milk from getting contaminated to a longer period of time.

Thus, the correct answer is option B.
