Optimal storage temperature for fresh fruits: physiological responses, quality retention, and shelf-life extension
Postharvest Quality
Every apple, peach, or berry you grow or buy has a metabolic sweet spot — store it too warm and it ripens to mush in days; store it too cold and invisible internal damage quietly ruins flavor and texture before you ever notice.
Fruits are still alive after they're picked, and temperature controls how fast they 'breathe' and ripen. Store them too warm and they race toward rot; store them too cold and you can trigger a kind of cold shock that ruins texture and flavor from the inside out. Because every fruit has its own ideal temperature range, one-size-fits-all refrigeration often does more harm than good.
Key Findings
Temperature directly controls respiration rate and ethylene gas production — the two main biological clocks driving how fast a fruit ripens and deteriorates after harvest.
Chilling injury is a real and distinct risk for cold-sensitive fruits (like mangoes, bananas, and avocados) stored below their minimum safe temperature, causing internal browning and flavor loss even before visible damage appears.
Climacteric fruits (like apples and tomatoes, which ripen after picking) and non-climacteric fruits (like grapes and citrus, which do not) require fundamentally different temperature strategies to maximize shelf life.

Keeping fruit at the right temperature after harvest is one of the most important factors in how long it stays fresh and nutritious. This review compiles what science knows about ideal storage temperatures for different fruits and the biological reasons why getting it wrong leads to spoilage.

Food preservation encompasses the methods and processes used to extend the shelf life of plant-based foods by inhibiting microbial growth, slowing oxidation of fats, and preventing enzymatic deterioration such as browning. For plant science, understanding the biochemical pathways behind
