| Abstract: | The physicochemical properties and fatty acid composition of mutton tallow prepared from tissues of suet and kidney of goat by rendering were analyzed.The saponification value,iodine value,and refraction index at 65 ℃ of the mutton tallow from suet were 196.8 mgKOH/g,47.9 gI/100 g,and 1.452 4,respectively;for the mutton tallow from kidney,they were 194.7 mgKOH/g,37.8 gI/100 g,and 1.452 0,respectively.The contents of palmitic acid,stearic acid and oleic acid in the mutton tallow from suet were 18.09%、20.85% and 45.54%,respectively;for the mutton tallow from kidney ,they were 17.06%,34.57% and 38.28%,respectively.The contents of oleic acid,stearic acid and palmitic acid in the Sn-2 position of the triglycerides in the mutton tallow from suet were 64.60%,11.52% and 9.84%,respectively.The contents of oleic acid,stearic acid and palmitic acid in the Sn-2 position of the triglycerides in the mutton tallow from kidney were 55.62%,20.70% and 12.65%,respectively.There were also a |
