APPLE POMACE - AN ENZYME-SYSTEM FOR PRODUCING AROMA COMPOUNDS FROM POLYUNSATURATED FATTY-ACIDS

This paper reports on the possibility of obtaining C-6 (hexanal) and C-10 (2,4-decadienal) volatile aldehydes by degradation of linoleic acid (C18:2 DELTA-9-12) under the action of the intrinsic enzyme systems found in apple pomace. More aroma compounds are produced by micronization of the pomace and by adding SO2 (60 ppm) and vitamin C (500 ppm), thereby synergistically counteracting oxidation of phenolic compounds, which is a limiting factor in bioconversion.
