UPSC Prelims 2013 question on Cold Storage Fruits Respiration

Fruits stored in a cold chamber exhibit longer storage life because:

  1. Exposure to sunlight is prevented
  2. Concentration of carbon dioxide in the environment is increased
  3. Rate of respiration is decreased
  4. There is an increase in humidity
Show answer

Answer: C. Rate of respiration is decreased

Analysis

Fruits remain fresh for a longer period in cold storage because low temperatures slow down the rate of respiration and metabolic activities. Reduced respiration delays ripening and decomposition, thereby extending storage life. Therefore, decrease in respiration rate is the primary reason for longer preservation of fruits in cold chambers.

Extra UPSC info

Cold storage is widely used in agriculture to reduce post-harvest losses of fruits and vegetables.
