[目的]对野生青荚叶脂肪酸和氨基酸营养成分进行评价.[方法]运用多种分析方法分析青荚叶的脂肪酸及氨基酸的组成及含量,并用必需氨基酸指数(EAAI)、氨基酸分(AAS)和化学分(CS)评价青荚叶中蛋白质营养价值.[结果]青荚叶中粗脂肪含量为4.27%,7种脂肪酸中不饱和脂肪酸占脂肪酸总含量的76.42%,饱和脂肪酸含量较低.青荚叶中蛋白质含量为7.74%.18种氨基酸总含量为6.19%,8种必需氨基酸占氨基酸总量的41.36%,9种药效氨基酸占氨基酸总量的60.74%,4种鲜味氨基酸占氨基酸总量的35.22%.AAS和CS均表明第一限制性氨基酸为赖氨酸.[结论]青荚叶口味鲜美,营养均衡,具有较高的开发利用价值.
Nutritional Evaluation of Fatty Acid and Amino Acid in Helwingia japonica
[Objective] To evaluate the amino acid and fatty acid content in wild Helwingia japonica.[Method] The nutritional components of Helwingia japonica were determined and evaluated by various analytical methods.The nutritional value of protein from Helwingia japonica was estimated by essential amino acid index (EAAI),amino acid score (AAS) and chemical score (CS).[Result] The results showed that the crude fat occupied 4.27% of its dry weight.The unsaturated fatty acids accounted for 70% of its total fat and the content of saturated fatty acid was low.The content of protein accounted for about 7.74% of its dry weight.Total contents of 18 types amino acid were 6.19%.Essential amino acid (EAA) accounted for 41.36% of total amino acid.The content of nine kinds of pharmacodynamics amino acid was 60.74% of total amino acid.The content of 4 kinds of flavor amino acid was 35.22% of total contents of amino acid.According to AAS and CS,the first limited amino acid was Lys.[Conclusion] Helwingia japonica with delicious taste and balanced nutrition is very suitable for eating as a new food and has vast prospects for developing and application.
