In post-harvest technology, the primary purpose of controlled atmosphere storage is to:
Show Hint
Controlled atmosphere storage prolongs freshness by reducing metabolic activity in produce.
Updated On: Jul 2, 2026
- Increase humidity levels
- Enhance color development
- Slow down respiration rate
- Promote ripening
Show Solution

The Correct Option is C
Approach Solution - 1
Controlled atmosphere storage involves adjusting oxygen, carbon dioxide, and nitrogen levels to slow down the respiration rate of stored produce. This technique extends shelf life and maintains quality by delaying ripening and senescence.

Approach Solution -2
Purpose-First: Produce keeps 'breathing' (respiring) after harvest, and faster respiration means faster spoilage/ripening — so the goal is to slow that process down.
Adjusting O₂, CO₂, and N₂ levels specifically slows the respiration rate, extending shelf life — matching option 3.
Increasing humidity, enhancing color, and promoting ripening are either side concerns or the OPPOSITE of what CA storage aims for (it DELAYS ripening, not promotes it).
