What is oxidative rancidity?

Answer 1

Rancidity is the chemical decomposition of fats, oils and other lipids. There are three basic types of rancidity. Hydrolytic rancidity occurs when water splits fatty acid chains away from the glycerol backbone in glycerides. Oxidative rancidity occurs when the double bonds of an unsaturated fatty acid react chemically with oxygen. Microbial rancidity refers to a process in which microorganisms such as bacteria use their enzymes, including lipases, to break down chemical structures in the fat. In each case, these chemical reactions result in undesirable odors and flavors.

Answer 2

Hydrolytic rancidity occurs when water splits fatty acid chains away from the glycerol backbone in triglycerides (fats). The chemical term is ester hydrolysis. Usually this hydrolysis process goes unnoticed, since most fatty acids are odorless and tasteless. When, however, the triglyceride is derived from short chain fatty acids, the released carboxylic acid can confer strong flavors and odors. A particular problem arises with butter, which contains triglycerides with a high content of butyric acid derivatives and acetic acids.That's it

Answer 3

Oxidative rancidity is a chemical reaction whereby fats and oils react with oxygen, leading to the breakdown of these lipids and the development of off-flavors and odors. This process is accelerated by exposure to light, heat, and metals. Antioxidants can help prevent oxidative rancidity by inhibiting the oxidation process.

Answer 5

Oxidative rancidity refers to the degradation by oxygen in the air. It primarily occurs with unsaturated fats and can be suppressed by the addition of antioxidants.
