天津地区引种的3个黑穗醋栗品种果实氨基酸组分与含量分析

Amino acid composition and content analysis of fruits of 3 black currant varieties introduced in Tianjin

对3个黑穗醋栗品种的果实氨基酸组分与含量的差异分析,旨在为黑穗醋栗资源品质研究和生产上提高果实品质的技术措施提供理论依据。以天津地区引种的‘大粒黑’‘布劳德’和‘丹丰’为试验材料,采用氨基酸自动分析仪对果实中19种氨基酸含量进行了测定,3个黑穗醋栗品种果实中氨基酸种类较齐全,除‘大粒黑’和‘丹丰’果实中不含鸟氨酸外。3个黑穗醋栗品种均含有7种人体必需氨基酸,10种非必需氨基酸和9种药用氨基酸。3个黑穗醋栗品种果实中氨基酸总量为534.32~734.80mg/100g,其中‘丹丰’含量最低,‘布劳德’最高。‘布劳德’果实中药用氨基酸含量最高。不同黑穗醋栗品种的人体必需氨基酸含量和药用氨基酸含量存在差异。相较于其他2个品种,‘布劳德’果实有更高的营养价值和医疗保健功效。

The differences of amino acid components and contents in fruits of three black currant varieties were analyzed in order to provide theoretical basis for the research on the quality of currant resources and the technical measures to improve the fruit quality in production.The contents of 19 kinds of amino acids in fruitsof the three black currantvarieties in Tianjin area were determined by automatic amino acid analyzer.The amino acids in the fruits of the three black currant varieties were relatively complete,and the other varieties all contained 19 amino acids measured in this study,except the‘big black’and‘danfeng’fruits which did not contain ornithine.It included 7 essential amino acids,10 non-essential amino acids and 9 medicinal amino acids.The total amount of amino acids in the fruits of the three black currant varieties was 534.32~734.80 mg/100 g,among which the lowest content was‘danfeng’and the highest was‘broad’.The amino acid content of"broad"fruit was the highest.The contents of essential amino acids and medicinal amino acids of different black currant varieties were different.Compared with the other two varieties,the fruit of"broad"has the highestnutritional value and health care effect.
