Extract

The reaction of thermal oxidation products of phospholipid fatty acids with other meat components is an important source of cooked meat flavour and odour (Mottram and Edwards, 1983) and preferences for meat from forage or concentrate finished beef have been attributed to differences in the feed fatty acids (Melton, 1990). Therefore modifying lipids to meet human dietary recommendations to raise the P:S and n-3:n-6 ratios of dietary polyunsaturated fatty acids (PUFA) is likely to affect meat quality. We have investigated the effect on eating quality, flavour volatiles and phospholipid fatty acid composition of feeding steers linseed, which is high in α-linolenic acid (18:3 n-3), and fish oil containing EPA (20:5 n-3) and DHA (22:6 n-3).
