Testing for hydrolytic stability is important for adhesives and other polymers that may be directly exposed to high humidity for long periods of time, as in tropical environments.
WebSummary. Lipolysis, the enzymic hydrolysis of milk lipids to free fatty acids and partial glycerides, is a constant concern to the dairy industry because of the detrimental effcts it can have on the flvor and other properties of milk and milk products. However, free fatty acids also contribute to the desirable flavor of milk and milk products ...

Web[Hydro-, 1 + -lysis.] (Chem.) A chemical process causing the splitting of a chemical bond by the addition of the elements of water. Where the bond which is split is not part of a ring structure, this process causes formation of two compounds from one compound plus water, as in the hydrolysis of the ester bonds of fats during {saponification}. hobby infographicFive pathways for rancidification are recognized: Hydrolytic Hydrolytic rancidity refers to the odor that develops when triglycerides are hydrolyzed and free fatty acids are released. This reaction of lipid with water may require a catalyst (such as a lipase, or acidic or alkaline conditions) leading to the formation of … Meer weergeven 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 Meer weergeven Despite concerns among the scientific community, there is little data on the health effects of rancidity or lipid oxidation in humans. … Meer weergeven • Deep frying § Oil deterioration and chemical changes • Fermentation • Food preservation • Lipid peroxidation • Preservative Meer weergeven Oxidative stability is a measure of oil or fat resistance to oxidation.
