插图:Rancidity is a term loosely applied to the occurrence of off- flavor and odor in oils/fats. This results from an oxidation of unsaturated fatty acids. However, hydrolysis, if it occurs, may give rise to off flavors and odors especially if the fat contains low molecular weight fatty acids ( butyric, caproic and caprylic).Basically, oxidative rancidity involves a free radical mechanism where oxygen is added to the fatty acid chain of a triglyceride, leading to the formation of peroxides. The autooxidation can be initiated and catalyzed by heat, light, divalent metal ions and enzymes such as lipoxygenase. The peroxides formed are in themselves not the contributors to the rancid off- flavors and off- odors characteristic of oxidized fats, but they are unstable once formed and later break down to form a myriad of lower molecular components ( e. g. aldehydes, ketones and hydroxyl groups) which are volatile and are mainly responsible for the off- flavor and odor.In hydrolytic rancidity, the triglyceride reacts with water and for each molecule of water in- volved one molecule of fatty acid is released. When a molecule of fat reacts with three molecules of water, glycerol and three fatty acids are formed. This reaction is catalysed by heat and enzymes known as lipases.
