To study the mechanism of the effect of fat oxidation on meat flavor formation,effects of oxidized fat and unoxidized fat on water-soluble products of the cysteine and glucose reaction system were investigated by the analysis of product color,elemental analysis,and thermal degradation volatile products.The results showed that low molecular weight compounds( < 3 000 Da) were the major part of water-soluble products,while both the compounds with molecular weight > 3 000 Da and ≤3 000 Da contributed to the col...
