太平洋褶柔鱼内脏团营养成分分析与评价

Analysis and evaluation of nutritional components of visceral mass from Todarodes pacificus

目的研究太平洋褶柔鱼(Todarodes pacificus)内脏团的营养成分和价值。方法通过系统测定太平洋褶柔鱼内脏团的基本营养成分组成、脂肪酸组成、氨基酸组成、矿物质元素组成和脂溶性维生素含量,对其营养品质进行分析评价。结果太平洋褶柔鱼内脏团的水分含量为(64.19±0.78)%,蛋白质、粗脂肪、碳水化合物和灰分的含量分别占干基的(49.68±1.89)%、(32.40±0.14)%、(10.31±1.94)%和(5.70±0.14)%;总脂质中甘油酯、磷脂和游离脂肪酸的含量分别为(55.42±2.65)%、(13.33±1.31)%和(22.64±0.70)%;总脂质中的多不饱和脂肪酸含量丰富,且主要为二十碳五烯酸(eicosapentaenoic acid,EPA)和二十二碳六烯酸(docosahexaenoic acid,DHA),二者分别占总脂肪酸含量的(11.56±0.04)%和(27.86±0.09)%;氨基酸组成符合联合国粮农组织/世界卫生组织规定的优质蛋白标准;矿物质元素含量丰富,Zn和Fe等微量元素的含量较高;维生素D和维生素E等脂溶性维生素的含量较为丰富。结论太平洋褶柔鱼内脏团是优质蛋白、Omega-3系列多不饱和脂肪酸、脂溶性维生素等营养成分的良好来源,值得进一步开发利用。

Objective To study the nutritional composition and value of the visceral mass from Todarodes pacificus.Methods The basic nutrient composition,fatty acid composition,amino acid composition,mineral element composition and fat-soluble vitamin content of the visceral mass from Todarodes pacificus were systematically determined,and the nutritional quality was analyzed and evaluated.Results The results showed that the moisture content of the visceral mass from Todarodes pacificus was(64.19±0.78)%,while the contents(dry weight)of protein,total lipids,carbohydrate and ash were(49.68±1.89)%,(32.40±0.14)%,(10.31±1.94)%and(5.70±0.14)%,respectively.The content of glycerides,phospholipids and free fatty acids in total lipids were(55.42±2.65)%,(13.33±1.31)%and(22.64±0.70)%,respectively.The total lipids were rich in polyunsaturated fatty acids,mainly eicosapentaenoic acid(EPA)and docosahexaenoic acid(DHA),which accounted for(11.56±0.04)%and(27.86±0.09)%of the total fatty acids,respectively.The amino acid composition metthe Food and Agriculture Organization/World Health Organization high quality protein standards.The mineral element content of the visceral mass from Todarodes pacificus were rich,while the content of Zn and Fe were high.The content of fat-soluble vitamins such as vitamin D and vitamin E of the visceral mass from Todarodes pacificus were also abundant.Conclusion The visceral mass from Todarodes pacificus is the good source of high-quality protein,omega-3 polyunsaturated fatty acids and fat-soluble vitamins,which will be worthy of further research and utilization.
