Question

Apples are wrapped in waxed paper to:

• A. \(\text{Prevent sunlight from changing its colour}\)
• B. \(\text{Prevent aerobic respiration}\)
• C. \(\text{Prevent injury}\)
• D. \(\text{To make it attractive}\)

Hint:

Waxed coatings on fruits reduce respiration, slow ripening, and extend shelf life.

Answer 1

The Correct Option is B

Step 1: Understanding the role of waxed paper. - Wax limits oxygen exchange, reducing aerobic respiration, which slows down ripening and spoilage.
Step 2: Explanation of incorrect options. - (A) Preventing sunlight color change: Sunlight has minimal effect due to the thick skin of apples.
- (C) Preventing injury: Packaging methods, not wax, protect against injury.
- (D) Making it attractive: Aesthetic appeal is a secondary reason.
Step 3: Selecting the correct option. Since waxed paper reduces aerobic respiration, the correct answer is (B) Prevent aerobic respiration.
