Question

The primary role of waxing in fruits and vegetables is to:

A.

Promote ripening

B.

Reduce transpiration and respiration

C.

Enhance color development

D.

Increase weight

Correct option is B

The correct answer is: B – Reduce transpiration and respiration
Explanation:
Waxing is applied to fruits and vegetables primarily to reduce transpiration (water loss) and respiration (metabolic activity). This helps in maintaining freshness, firmness, and extending shelf life during storage and transportation.
Wax forms a thin coating on the surface, minimizing moisture loss and slowing down deterioration without affecting the internal quality of the produce.
Information Key Points:
  • Common in: Apples, citrus fruits, cucumbers, tomatoes, etc.

  • Types of waxes used: Beeswax, carnauba wax, paraffin wax

Knowledge Booster:

  • Promote ripening: Achieved through ethylene treatment.

  • Enhance color development: Done using ethylene or light exposure.

  • Increase weight: any gain is minimal and not the primary purpose.
