扇贝边脂肪酸成分的研究

Study on Constituents of Fatty Acids in Scallop Wastes

以快速脂肪提取器提取脂肪，经甲酯化后，利用５０ｍ×０．３５ｍｍｉ．ｄ．ＰＥＧ－２０Ｍ玻璃毛细管柱分析了其中的饱和、不饱和脂肪酸．面积归一化法定量．结合ＧＣ／ＭＳ，共鉴定了４０种脂肪酸，占脂肪酸总量的９３．５％，其中不饱和脂肪酸为６６．７％．

Fat of scallop wastes is extracted by rapid fat extractor.After being esterified,the saturated and unsaturated fatty acid methyl esters are separated and determined by a 50m× 0.35mmi.d.PEG 20M glass capillary column and hydrogen flame ionization detector(FID).Forty peaks are identified with gas chromatography/mass spectrometry,and quantified with area normalization method.The amount of identified fatty acids attains 93.5% of total amount of them,of which the unsaturated fatty acids reach 66.7%.
