不同品种荔枝果实游离氨基酸分析
Analysis of Free Amino Acids in Litchi Fruits from Different Cultivars
摘要
Abstract
An AccQ·tag precolumn derivatization and reversed phase HPLC method was presented to determine the contents of 17 free amino acids in litchi fruits from 5 different cultivars,Ziniangxi,Dadingxiang,Heiye,Lanzhu and Tianyan.The method proved highly reproducible and precise.The ratio of essential amino acids to total amino acids was 36.4% and to non-essential amino acids 0.57 in Tianyan,indicating good agreement with the ideal human protein requirements.The five litchi cultivars were all rich in medicinal,umami and sweet amino acids with a difference in their contents and small amounts of several aromatic amino acids were also found.Therefore,different litchi cultivars distinctly differ in taste and flavor.关键词
