摘要: 在盐碱环境下,测定不同果肉颜色火龙果品种‘银龙'和‘白玉龙'果实的氨基酸和8种矿质元素(钾、镁、钙、钠、铁、锌、锰和铜)含量。结果表明:盐碱环境下生产的火龙果含有17种氨基酸,氨基酸种类齐全,‘银龙'和‘白玉龙'中总氨基酸含量分别为765.62 mg·hg-1FW和1 122.60 mg·hg-1FW,其中谷氨酸的含量最高,‘银龙'和‘白玉龙'中分别达到了15.88%和20.77%;药用氨基酸也较为丰富,‘银龙'和‘白玉龙'中分别为62.79%和66.88%。2个参试品种中的钾、镁、钙、铁、锌等矿质元素含量均高于种植于其他生态环境下相应肉色火龙果。并探讨了盐碱环境对火龙果果实氨基酸、矿质元素等营养品质的影响,以及盐碱环境下火龙果种植模式的社会经济效益。

Abstract: Contents of amino acids and 8 minerals(i.e.,K,Mg,Ca,Na,Fe,Zn,Mn and Cu)in two of pitaya fruit,Yinlong and Baiyulong,grown in saline habitats were determined.The results indicated that the pitaya fruits contained 17 amino acids.The total amino acid contents of Yinlong and Baiyulong were 765.62 mg·g-1FW and 1,122.60 mg·g-1FW,respectively.Glutamic acid cotent was the highest among them,accounting for 15.88% and 20.77% of the total amino acids in Yinlong and Baiyulong,respectively.The pharmacological amino acids were rich in the pitaya fruits,constituting 62.79% and 66.88% of the total amino acids in Yinlong and Baiyulong,respectively.The contents of K,Mg,Ca,Fe and Zn were higher in the pitaya fruits from the plants grown in saline habitats than otherwise.Thus,the effect of cultivation of pitaya fruit plants under saline conditions on the fruit's chemical contents,quality and socio-economic benefits are presented for future reference.
