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).

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.
prevent rancidity???? if it so then the answer is - 1) BHA {Butylated Hydroxy-Anisole} 2) BHT {Butylated Hydroxy-Toluene} Hope it helped!!!
Carbon dioxide CO2 is usually the main triatomic gas present in dry air. Sulfur dioxide, SO2 is also present in many locations.
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.
The majority of injuries to gas-containing organs are usually attributed to which of the following?
Think of bushings as they really are: a consumable bearing. They don't move and are not as hard as bearings. They are composite material usually containing a lot of brass. They are present in the engine and the transmission.
to revent it from rancidity Usually as a flavouring or preservative. e.g. Pickled Onions are preserved in vinegar (an acid) the vinegar also adds flavour to the onions.
Phosphorus is a solid chemical element up to 44,2 0C - the melting point of the allotrope white phosphorus. All the rocks containing phosphorus are also solids.
