Food Processing

Step 1: Understanding the Concept:
The question asks to define the atmospheric condition in hypobaric storage. The prefix "hypo-" means 'under' or 'low', and "baric" refers to pressure.

Step 2: Detailed Explanation:
Hypobaric storage, also known as low-pressure storage, is a preservation technique where produce is stored in a refrigerated, sealed chamber at a pressure well below normal atmospheric pressure (i.e., under a partial vacuum). The low pressure environment reduces the partial pressure of oxygen, which slows down the rate of respiration. It also facilitates the removal of volatile compounds like ethylene from the produce, further slowing down ripening and senescence. Therefore, the defining characteristic of hypobaric storage is a low-pressure atmosphere, usually combined with low temperature and high humidity.

Step 3: Final Answer:
In hypobaric storage, the produce is stored under a low pressure atmosphere.

Concept: Improved crop varieties are developed for higher yield and resistance to multiple diseases. "Arka" varieties are developed by IIHR (Indian Institute of Horticultural Research).
Step 1: Understanding Arka Rakshak.
Arka Rakshak is a hybrid variety known for its high yield and disease resistance.
Step 2: Identifying the crop.
It is a variety of tomato developed for improved productivity.
Step 3: Triple resistance.
It shows resistance to three major diseases:

• Bacterial wilt
• Early blight
• Leaf curl virus

Step 4: Evaluating the options.

• Brinjal Not correct
• Tomato Correct
• Chilli Not correct
• Cabbage Not correct

Step 5: Additional insight.
Arka Rakshak produces firm, round fruits suitable for both fresh consumption and processing, making it popular among farmers.
Step 6: Conclusion.
Thus, Arka Rakshak is a high-yielding triple-resistant variety of tomato.
