摘要
[目的]测定常见果蔬中游离氨基酸的含量。[方法]用氨基酸全自动分析仪测定了30种常见果蔬中各种游离氨基酸的组成。[结果]龙眼、香蕉、菠萝蜜、西瓜在30种果蔬中游离氨基酸总量最高,而红玫瑰葡萄、香梨、苹果、火龙果、猕猴桃中游离氨基酸含量相对较低。其中,荔枝、龙眼、西红柿、菠萝蜜中γ-氨基丁酸(γ-GABA)含量较高;香蕉、西瓜、黄瓜、杏中游离苏氨酸含量高;樱桃、香蕉、甘蔗汁中游离丝氨酸含量较高;西红柿、西瓜、游离谷氨酸较高;百香果中游离脯氨酸高。[结论]研究可为进一步探究果蔬营养成分,开发新产品提供参考。
[ Objdctive ] To determine the content of free amino acids in common fruits and vegetables. [ Method ] Free amino acids in 30 kinds of fruit and vegetable samples were determined by automatic amino acid analyzer. [Result] The results showed that the free amino acids of longan, banana and jackfruit were the highest in the samples and red grape, pear, apple, pitaya, kiwifruit were the lowest. Litchi, longan, tomato and jackfruit contained higher ~/-GABA. Banana, watermelon, cucumber, apricot contained higher threonine. Cherry, banana and sug- arcane contained higher serine. Tomato and watermelon contained higher glutamic acid. Passionfruit contained higher proline. [ Conclusion] The study could provide reference for further exploring nutrients in fruit and vegetable, broadening market and developing new products.
