Extract

During cooking, chemical reactions within the muscle produce volatile and non-volatile compounds characteristic of meat aroma and taste. Polyunsaturated fatty acids (PUFA) are essential in these reactions (Mottram and Edwards, 1983). In ruminants, differences in intramuscular PUFA composition have been classically associated with high n-3 content in grass fed animals and high n-6 content in concentrate fed animals. We investigated the effect on odour perception of in vitro reactions between linoleic and α-linolenic acids in the presence of cysteine and ribose, when they were present in ratios similar to those found in meat from animals reared on forage- or concentrate-based diets.
