5个杨桃品种果实氨基酸含量及组成分析

利用氨基酸分析仪测定了5个杨桃品种果实中17种氨基酸含量,为杨桃的良种选育提供依据。结果表明,杨桃果实中氨基酸种类较齐全,5个杨桃品种果实均含有测定的17种氨基酸,包括7种人体必需氨基酸和2种儿童必需氨基酸。5个杨桃品种果实中氨基酸总量为392.40～541.88 mg.（100 g）-1,含量最低的是红龙杨桃,最高的是台湾软枝杨桃。不同杨桃品种的人体必需氨基酸含量、儿童必需氨基酸含量和味觉类氨基酸含量存在差异。与其他水果比较,杨桃果实中Glu、Ser、Cys等3种氨基酸含量较高。

Content and Composition of Amino Acid in Five Caramhola Cultivars Fruit

In order to study the effect of different cultivar on fruit flavor and nutritional quality,the content of amino acid in 5 caramhola cultivars fruit was determined in the paper.The results showed that 5 caramhola cultivars fruit all contained 17 kinds of amino acids,among of which 7 essential amino acids including Phe,Thr and Lys were essential to human body,as well as His and Arg were semi-essential amino acids.Total content of amino acids in 5 caramhola cultivars fruit ranged from 392.40 to 541.88 mg·（100 g）-1,the lowest of which ＇Yingshianhaibian＇ caramhola,the highest was ＇Erse＇ caramhola.Moreover,different cultivars of caramhola had also obvious difference in the content of essential amino acids,semi-essential amino acids and taste amino acids.Compared with other fruit,Glu,Ser and Cys in caramhola fruit were higher relatively.
