Question:
The fruits of which citrus are subjected to low temperature storage of \(5^\circ C\) to \(10^\circ C\) for a period of 4 to 6 weeks for removal of acidity and improvement in sugar/acid ratio?
The fruits of which citrus are subjected to low temperature storage of \(5^\circ C\) to \(10^\circ C\) for a period of 4 to 6 weeks for removal of acidity and improvement in sugar/acid ratio?
Show Hint
Remember citrus low temperature treatment:
- Temperature: \(5^\circ C\)
- Duration: 4-6 weeks
- Purpose: Reduce acidity, improve sugar/acid ratio
- Used for: Mandarin, sweet oranges
- Also helps in degreening and quality improvement
- Temperature: \(5^\circ C\)
- Duration: 4-6 weeks
- Purpose: Reduce acidity, improve sugar/acid ratio
- Used for: Mandarin, sweet oranges
- Also helps in degreening and quality improvement

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
This question tests knowledge of postharvest treatment of citrus fruits to improve quality.
Step 2: Detailed Explanation:
Some citrus fruits, especially mandarins and sweet oranges, require low temperature storage to reduce acidity and improve sugar-acid ratio.
The process involves storing fruits at \(5^\circ C\) for 4-6 weeks.
During this period:
- Respiration slows down, reducing acid metabolism.
- Sugar levels increase relative to acids.
- The sugar/acid ratio improves, enhancing taste.
Other temperatures:
- \(8^\circ C\): Too high for effective acid reduction.
- \(10^\circ C\): May not be sufficient for optimal results.
- \(14^\circ C\): Unsuitable for this purpose.
This treatment is particularly important for Nagpur mandarin, Kinnow, and some sweet orange varieties.
Step 3: Final Answer:
Thus, the correct temperature is \(5^\circ C\), which corresponds to option (A).
