Storage life of fruits and vegetables is greatly extended by which practice?

• A. Removing field heat and cooling as soon after harvesting as possible
• B. Storing at room temperature
• C. Exposing to direct sunlight after harvest
• D. Waiting several days before cooling

Answer: (A)

Lowering field heat by cooling fruits and vegetables as soon after harvest as possible is the most effective way to extend storage life because temperature directly drives the rate of aging in produce. When produce is still warm, respiration speeds up, enzymes work faster, moisture is lost more quickly, and microbes can grow more rapidly. Cooling slows respiration and microbial activity, preserves texture and flavor, and delays ripening and spoilage. Delaying cooling or exposing produce to heat or sunlight keeps temperatures high, accelerating deterioration and shortening shelf life. Storing at room temperature or waiting days before cooling would unknowingly boost spoilage, not prevent it.
