摘要
为评价琼枝麒麟菜(Eucheuma gelatinae)的营养价值,提高其综合应用价值,测定了琼枝麒麟菜的基本营养成分、氨基酸、脂肪酸以及矿物元素,对其营养价值进行评价。结果表明:琼枝麒麟菜的水分、灰分、粗纤维、粗脂肪、粗蛋白以及总碳水化合物的质量分数分别为12.03%、10.63%、5.03%、0.25%、3.73%和73.36%;含有17种氨基酸,其中包括8种必需氨基酸,第一限制性氨基酸为色氨酸;含有10种脂肪酸,包括具有重要生理功能的花生四烯酸、二十二碳五烯酸以及二十二碳六烯酸;富含Na、Mg、Ca、Fe、Zn、Cu。研究表明琼枝麒麟菜具有较高的营养保健价值和应用开发前景。
To evaluate the nutritional value of Eucheuma gelatinae and improve its comprehensive application potential,this experiment determined E.gelatinae basic nutrients,amino acids,fatty acids and mineral elements.Results showed that the mass fractions of water,ash,crude fiber,crude fat,crude protein and total carbohydrate of E.gelatinae were 12.03%,10.63%,5.03%,0.25%,3.73%and 73.36%,respectively.It contained 17 amino acids including eight essential amino acids,and the first limiting amino acid was tryptophan.There were ten kinds of fatty acids that were found in E.gelatinae,and three of which included arachidonic acid,eicosapentaenoic acid and docosahexaenoic acid with important physiological functions.Moreover,Na,Mg,Ca,Fe,Zn and Cu were also found to be rich in E.gelatinae.The findings indicate that E.gelatinae has high nutritional value and application prospects.
