UPSC 2013: Fruits stored in a cold chamber exhibit longer storage life because
(a)exposure to sunlight is prevented
(b)concentration of carbon dioxide in the environment is increased
(c)rate of respiration is decreased
(d)there is an increase in humidity
Attempt This Question
Not attemptedCorrect Answer: (c) rate of respiration is decreased
Refrigerated (cold-storage) conditions slow the biochemical respiration of harvested fruits, delaying ripening, senescence and microbial spoilage, and thereby extending shelf-life. Preventing sunlight, raising CO₂ or humidity can have additional effects, but the primary, universally exploited mechanism is the temperature-induced reduction of the respiration rate. Hence option (c) alone gives the fundamental reason. ([britannica.com](https://www.britannica.com/topic/fruit-processing/Maturation-and-spoilage?utm_source=openai))
