摘要
【目的】对3个红色砂梨新品种的果实氨基酸组分和含量的差异分析,旨在为红色砂梨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。【方法】以‘红脆‘’珍珠红’和‘彩云红’3个拟将大面积推广的红色砂梨新品种为试验材料,采用氨基酸自动分析仪对果实中17种氨基酸的含量进行了测定。【结果】3个中熟红色砂梨果实中氨基酸种类齐全,均含有测定的17种氨基酸,包括7种人体必需氨基酸、2种儿童必需氨基酸及8种其他氨基酸。3个品种果汁中氨基酸总量为2 083～4 118 mg·mL-1,其中含量最低的是红脆,最高的是珍珠红。【结论】不同红色砂梨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。相较于其他2个品种‘,彩云红’品种更符合儿童生长发育果种中营养的需要,鲜味特性更突出,可以将此特性作为下一步果实品质开发的方向或为良种的选育提供依据。
【Objective】Analysis the amino acids of fruits variance in three new varieties of red sandy pear,in order to provide theoretical basis,which study on resource quality and production of red sand pear.【Methods】The content of 17 kinds of amino acids in fruits was determined by using an automatic amino acid analyzer with three new varieties of red pears,which were intended to be popularized in large area,called’Hongcui’’Zhengzhuhong’and’Caiyunhong’.【Results】The results showed that the amino acids in 3 medium ripe red pear fruits were all of various kinds,all containing 17 amino acids measured,including 7 essential amino acids for human body,2 essential amino acids for children and 8 other amino acids.The total amount of amino acid in the three kinds of fruit juice was 2 083-4 118 mg·mL-1,among which the lowest was’Hongcui’and the highest was’Zhengzhuhong’.【Conclusion】There was disparity of different red pears in forms of the content of essential amino acid content of human,the essential amino acid content of children as well as the kind of taste amino acid.Compare to’Hongcui’and’Zhengzhuhong’’Caiyunhong’fits more the growth of children.In the next step,this characteristic can be used as the direction of fruit quality development or selection of good varieties.
