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.

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

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.

What is the difference between oxidative and hydrolytic enzymes?

Hydrolytic rancidity involves reacting with water to break ester bonds. A fatty acid and glycerol is formed in this process.On the other hand, oxidative rancidity involves oxygen reacting with the C=C double bond of the lipid.


What is a major cause of rancidity of lipids in foods is exposure to?

Rancidity is caused by hydrolysis and oxidation. Heat, moisture and exposure to light will increase these chemical reactions and thus increase the likelikhood of the onset of rancidity.


Which two antioxidants which are usually added to fat and oil containing foods to present rancidity?

There are two types of rancidity: oxidative rancidity and hydrolytic rancidity. Citric acid and phosphoric acid are added to prevent rancidity in fats. Other antioxidants include butylated hydroxyanisole (BHA)and butylated hydroxytoluene (BHT).


How you check rancidity?

we can check rancidity thru two methods :- check the smell usually it becomes foul and see if the the fats and oils are oxidized ,if yes then it is rancidity.
