Question

Which of the following is/are method(s) used to prevent food decay?

• A. Use pure water and pure raw materials
• B. Refrigeration of food items
• C. Add synthetic chemicals for food colouring
• D. Store food substances in a dry place

Answer 1

Answer: (B), (D)

The correct options are
B

Refrigeration of food items

D

Store food substances in a dry place

Food gets decayed mainly due to the decomposition activities of bacteria, fungi etc. Most microorganisms are generally destroyed at a high temperature when cooking but for storage, refrigeration is an option because, at a very low temperature, the microorganisms become inactive. Food substances need to be stored in dry areas because food stored shouldn't contain moisture which attracts microorganisms. Cleaning the food substances thoroughly before cooking and using food colouring will not help to prevent decay.
