Answer 1

Answer:

C. Waxing of fruits and vegetables

• Wax Emulsions (W and O compositions): Formulations developed for coating post-harvest produce are commonly referred to as Wax Emulsions (such as standard aqueous formulations designated as 'W' and 'O' compositions developed by food research institutes like CFTRI).

• Purpose: These wax-in-water or water-in-wax emulsions are applied to fresh fruits and vegetables to form a thin protective coating.

• Benefits:

  • Reduces moisture loss and rate of respiration.

  • Protects fruits and vegetables from fungal decay and spoilage during transport.

  • Extends the shelf life and enhances the appearance/shine of produce.
