Abstract: | An estensive survey of the literature on lipids of beef covering the past fouteen years revealed that a number of factors, such as sex, age, and diet of animal, and analytical method, can affect the lipid content and fatty acid composition of beef. The feeding regimen of the animal was a factor considered in evaluating data for the food table. Extraction method was important in assessing information on lean tissue lipids. Statistical analysis showed that fatty acid patterns for the separable fat and separable lean of various meat cuts were not significantly different at the 5 per cent level. Cooking by dry or moist heat has little effect on relative fatty acid composition. Methods for converting methyl ester data into per cent composition of fatty acids in the meat cut are presented. A comprehensive table of fatty acids per 100 gm. separable lean, separable fet, and total edible portions of Choice grade cuts of beef is given, as well as a table acids per 100 gm. fat for lean and adipose tissues. |
