川中丘陵区灰毡毛忍冬氨基酸组分及营养价值分析

摘要

研究了引种至川中丘陵地区的灰毡毛忍冬花营的氨基酸组分及含量，并对其进行了营养评价。使用烘箱、凯氏定氮仪、氨基酸自动分析仪分别测定了灰毡毛忍冬花蕾的水分、蛋白质含量和氨基酸含量。结果表明：引种至川中丘陵地区的灰毡毛忍冬花蕾蛋白质含量为14．37％；从花蕾中检测出了17种氨基酸，其中7种为人体必需氨基酸。总氨基酸含量、必需氨基酸含量、非必需氨基酸含量、风味氨基酸含量和药用氨基酸含量分别为133．74mg／g、59．42mg／g、114．91mg／g和80．29mg／g。必需氨基酸与非必需氨基酸比值、必需氨基酸与总氨基酸比值分别为O．79和0．44；应用氨基酸比值系数法进行分析，氨基酸比值和氨基酸比值系数分别为0．97—1．32和70．76。引种至川中丘陵区的灰毡毛忍冬花蕾氨基酸含量高且稳定，氨基酸组成满足理想氨基酸模式，营养价值均衡；可以直接食用或作为开发保健品的优质原料。%In order to research the amino acid components and contents of Lonicera macranthoides Hand. -Mazz. introduced into the middle of the hilly area of Sichuan and evaluate their nutrition value, the contents of water, protein and amino acids in it were determined by the Oven, Kieldahl instrument and HITICHIL-8800 automatic analysis in- strument, respectively. The results showed that the content of the protein was 14.37%. There were 17 kinds of amino acid, wherein 7 was essential amino acid for human. The contents of total amino acids, essential amino acids, nones- sential amino acids, flavor amino acids and medicinal amino acids were 133.74 mg/g, 59.42 mg/g, 114.91 mg/g, and 80.29 mg/g, respectively. The ratio of essential amino acids to nonessential amino acids and essential amino acids to total amino acids were 0.79 and 0.44, respectively. Analyzing the amino acids via the amino acids ratio coef- ficient method, the amino acids ratio and the ratio coefficient were 0.97 - 1.32 and 70.76, respectively. The con- tents of amino acids of Lonicera macranthoides Hand. -Mazz. introduced to the middle of the Sichuan Hilly Basin were high and steady, the constitute of amino acids met the standard model. The nutritional value was balance. They could be used to eat directly or used as raw materials with high quality to develop health care products.
