| Abstract: |
| In order to improve the utilization value of sheep tail, the oil was extracted from Sunite sheep tail by vacuum extraction method, and its physicochemical properties were determined. The sheep tail oil was separated into solid fat and liquid oil by dry fractionation, and the fatty acid compositions of the crude oil, solid fat and liquid oil were analyzed by gas chromatography-mass spectrometry. The results showed that the moisture and volatile matter content of Sunite sheep tail oil was 8.63%, acid value was 0.67 mgKOH/g, saponification value was 180.1 mgKOH/g, and iodine value was 45.48 gI/100 g. A tatal of 16 fatty acids were detected in the three kinds of oils, and the main fatty acid was palmitic acid, oleic acid and stearic acid. The content of unsaturated fatty acids in liquid oil was higher than that in the crude oil and solid fat. |
