摘要
为了探讨白肉枇杷和红肉枇杷果实的风味和营养品质的差异,利用氨基酸自动分析仪测定了5个晚熟枇杷品种果实的氨基酸含量。结果表明,新白1号枇杷果实中天门冬氨酸和谷氨酸等鲜味类氨基酸含量占总氨基酸的53.9%,明显高于红肉枇杷中的含量;而红肉枇杷的甜味类氨基酸和芳香类氨基酸含量略高于白肉枇杷。白肉枇杷中药用氨基酸含量高于红肉枇杷,而红肉枇杷符合氨基酸模式谱的指标多于白肉枇杷。
To study differences between white and red flesh loquat fruit in flavor quality and nutrition quality, contents of amino acids in five late ripening Loquat fruits was detected by Automatic Amino Acid Analyzer. The results showed that the contents of Aspartic Acid （Asp） and Glutamic Acid （Glu） belong to delicious taste amino acid in Xinbai 1 fruits accounted for 53.9% of total amino acids, which were obviously higher than that in red flesh loquat fruit while sweet taste and aromatic amino acid in red flesh fruit were slight higher than that in white flesh fruit. The content of medical amino acid in white flesh loquat fruit was higher while amino acid indexes accord with the pattern spectrum in red flesh fruit were more than those in white flesh fruit.
