Abstract

Unsaturated fatty acids (UFAs) as well as natural food ingredients containing them are being added to food products more often. Unfortunately, UFAs are susceptible to oxidative degradation, and can therefore reduce the stability of a food matrix. The assessment of oxidation and stability of lipids has never been standardized, and has long included a variety of approaches. These techniques can differ greatly in the reactions/compounds being assessed, and therefore the eventual conclusions may be affected dramatically by selection of methodology. The aim of this review is to provide an update on the methods of historic and current use for the assessment of lipid stability in food products. Accelerated storage tests, assessment methods of lipid oxidation, and rapid indicators of stability are discussed in the contexts of their modern prominences, uses, and concerns.
