Question

Define the following term:

Rancidity

Answer 1

Rancidity is the process by which fats and oils undergo chemical decomposition, resulting in the unpleasant smell, taste, and appearance of the food. This usually happens when fats oxidise or hydrolyse, leading to off-flavours and odours often described as stale or sour. Rancidity can occur due to exposure to air, light, heat, or certain microorganisms.
