Question:
Gaseous concentrations are maintained precisely in which type of storage?
Gaseous concentrations are maintained precisely in which type of storage?
Show Hint
CA storage dynamically controls and maintains exact gas setpoints, whereas MAP allows gas concentrations to fluctuate during storage.
Updated On: Sep 15, 2026
- Controlled atmosphere storage
- Active modified atmosphere storage
- Passive modified atmosphere storage
- Hypobaric storage
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Atmospheric gas composition modification is widely used to suppress the respiration rate of fresh perishable horticultural produce.
Step 2: Detailed Explanation:
In Controlled Atmosphere (CA) storage, gas concentrations of $\text{O}_2$, $\text{CO}_2$, and $\text{N}_2$ are continuously sensed and dynamically controlled at fixed target setpoints throughout storage using external scrubbers, nitrogen flushers, and catalytic converters.
In Modified Atmosphere (MA) systems, initial gas composition is altered but allowed to passively or actively drift over time.
Step 3: Final Answer:
Hence, gaseous concentrations are maintained precisely in Controlled Atmosphere storage.
