Question

In hypobaric storage, the produce is stored under

• A. High pressure atmosphere
• B. Low temperature atmosphere
• C. Low pressure atmosphere
• D. High temperature atmosphere

Hint:

Break down scientific terms. "Hypo-" means low, "Hyper-" means high. "Baric" refers to pressure. So, Hypobaric = Low pressure, Hyperbaric = High pressure. This helps in decoding many technical terms.

Answer 1

The Correct Option is C

Step 1: Definition:
The question requires defining the atmospheric condition in hypobaric storage. "Hypo-" means "under" or "low," and "baric" relates to pressure.

Step 2: Elaboration:
Hypobaric storage, or low-pressure storage, preserves produce in a refrigerated, sealed chamber at a pressure significantly below normal atmospheric pressure (a partial vacuum). This low-pressure environment lowers the partial pressure of oxygen, slowing respiration. It also removes volatile compounds like ethylene, delaying ripening and senescence. Thus, hypobaric storage is characterized by a low-pressure atmosphere, often coupled with low temperature and high humidity.

Step 3: Answer:
Produce in hypobaric storage is kept in a low-pressure atmosphere.
