Question

Bananas can be prevented from overripening by

• A. Maintaining them at room temperature
• B. Refrigeration
• C. Dipping in ascorbic acid solution
• D. Storing in a freezer

Answer 1

Answer: (D)

Storing in a freezer

During ripening process, plants produce ethylene gas. To prevent overripening of bananas, the chemical reaction of ripening process needs to slow down. Cold temperatures will slow down the reaction and hence delay the ripening of banana. However, storing in freezer will slow down the ethylene emission more than refrigerating it.

Thus, the correct answer is option D.
