fatty acid
carboxylic acid with a long aliphatic chain, either saturated or unsaturated
trans fat
type of unsaturated fat that occurs in small amounts in nature, but is also produced industrially from vegetable fats for use in foods
saturated fat
fat in which the fatty acid chains have all or predominantly single bonds
rancidification
Rancidification is the process of complete or incomplete autoxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action, producing short-chain aldehydes, ketones and free fatty acids.
unsaturated fat
fat or fatty acid in which there is at least one double bond within the fatty acid chain
smoke point
burning point of oil and fats
iodine value
mass of iodine in grams that is consumed by 100 grams of a chemical substance
acid value
mass of potassium hydroxide (in mg) necessary to neutralise the free fatty acids contained in 1 g of fat
degree of unsaturation
term in organic chemistry
hydrogenated oils
Hydrogenation of fat
Peroxide value
peroxide functional group content index for a fat or fatty oil
cloud point
temperature below which a transparent solution becomes non-transparent
