Enzymatic Oxidation of Unsaturated Fatty Acids and Carotenoids in Tomato Fruit
Enzyme-catalyzed decolourization of naturally occurring pigments through coupled oxidation with unsaturated fatty acids was observed more than 40 years ago. The enzyme lipoxygenase /EC.188.8.131.52/ which catalyzes the oxidation of polyunsaturated fatty acids has been found to cause a loss in the colour intensity of many foods of plant origin during storage and processing1. Moreover, lipixygenase can effect by alternative ways the synthesis and stability of plant pigments2.
