摘要
[目的]为半刺厚唇鱼肌肉脂肪酸营养评价及其配合饲料的研制提供科学依据。[方法]对半刺厚唇鱼肌肉中脂肪酸组成及含量进行测定与分析。[结果]半刺厚唇鱼肌肉中共检出26种脂肪酸,其中饱和脂肪酸(SFA)10种、不饱和脂肪酸(UFA)16种;各脂肪酸中相对含量最高的为油酸(C18∶1,26.7%),其次分别为棕榈酸(C16∶0)、棕榈油酸(C16∶1)、亚油酸(C18∶2)和二十二碳六烯酸(DHA),这5种脂肪酸的相对含量占脂肪酸总量(FA)的80%以上;肌肉脂肪酸种类以不饱和脂肪酸为主,占比达63.9%,其中,单不饱和脂肪酸(MUFA)、多不饱和脂肪酸(PUFA)、EPA+DHA+AA和必需脂肪酸(EFA)的相对含量分别为42.3%、21.6%、10.3%和10.3%。[结论]半刺厚唇鱼是一种脂肪酸含量丰富、营养价值较高的优质淡水鱼类。
[Objective]The study aims to provide a scientific basis for the nutritional evaluation of the muscle fatty acids and feed development of Acrossocheilius hemispinus.[Method]The fatty acid composition and content in muscle of A.hemispinus was determined and analyzed.[Result]The results showed that 26 kinds of fatty acids were detected in the muscle of A.hemispinus,including 10 kinds of saturated fatty acids(SFA)and 16 kinds of unsaturated fatty acids(UFA).The highest relative content of fatty acids was oleic acid(C18∶1),which was as high as 26.7%,followed by palmitic acid(C16∶0),palmioleic acid(C16∶1),linoleic acid(C18∶2)and dodecaenoic acid(DHA).The relative content of these five fatty acids accounts for more than 80%of the total fatty acid(FA);the muscle fatty acids are dominated by unsaturated fatty acids,accounting for 63.9%of the total,and the relative contents of monounsaturated fatty acids(MUFA),polyunsaturated fatty acids(PUFA),EPA+DHA+AA and essential fatty acids(EFA)were 42.3%,21.6%,10.3%and 10.3%,among them respectively.[Conclusion]A.hemispinus is a kind of high quality freshwater fish with rich fatty acid content and high nutritional value.
