应用响应面优化辣木γ-氨基丁酸富集工艺研究

摘要

The γ-aminobutyric acid (GABA) enrichment technology in Moringa was optimized through single factor experiments,the steepest ascent experiment and a response surface design.An optimized technology was developed as follow:The fresh leaves of Moringa were treated in vacuum at 45 ℃ for 34 h and dired at 50 ℃.The content of GABA in Moringa was (19.70±0.16) mg/g,it was 2.63 times than that of the control.This study would provide technical support for the development of GABA-rich Moringa food.%通过富集方式和干燥方法的单因素实验,最陡爬坡试验和响应面设计,优化辣木鲜叶γ-氨基丁酸(γ-aminobutyric acid,GABA)的富集工艺.建立的辣木鲜叶中GABA最适富集条件为辣木鲜叶在45℃下,真空处理34 h,然后50℃干燥.该条件处理的辣木GABA含量为(19.70±0.16)mg/g,是对照的2.63倍.
