Rancidity is the spoilage of food containing fats and oils due to oxidation, leading to an unpleasant taste and odor.

Extra Info

Types of Rancidity:

  1. Oxidative Rancidity – Occurs when fats react with oxygen, forming peroxides and aldehydes.
  2. Hydrolytic Rancidity – Breakdown of fats due to moisture, releasing free fatty acids.
  3. Microbial Rancidity – Caused by microorganisms breaking down fats.

Prevention of Rancidity:

  • Using antioxidants (e.g., BHA, BHT, vitamin C)
  • Storing food in airtight containers
  • Refrigeration to slow oxidation
  • Using nitrogen packaging to remove oxygen (common in chips packets)
