oxidation

oxidationThe type of chemical reaction is oxidation. Definition: Rancidity is the process of slow oxidation of oil and fat present in the food materials resulting in the production of foul odour and taste in them.

Rancidification is the process of complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, or moisture or by bacterial action, resulting in unpleasant taste and odor. ... When these processes occur in food, undesirable odors and flavors can result.

There are two basic types or causes of rancidity that cause and/or contribute to the degradation of stored edible oils: oxidative and hydrolytic. Oxidative rancidity, known as autoxidation, occurs when oxygen is absorbed from the environment.
