Question

Boiling and refrigeration prevent microbial growth.

• A. True
• B. False

Answer 1

The correct option is A True

Boiling and refrigeration prevent around 70 percent of microbial growth. During boiling, microorganisms which cannot tolerate the heat will die. Thus, it helps in preservation. Refrigerators have low-temperature conditions. Since microbes do not get optimum temperature for growth, their growth will be inhibited. Pasteurization developed by Louis Pasteur is used till today to preserve milk.
