摘要
Abstract
The accumulation of GABA in rice bran by glutamate decarboxylase(GAD) ,and the purification of GABA enriched solution using cation ion exchange resin were investigated. The optimal accumulation conditions of GABA were determined as described below: the ionic strength of citric acid-disodium hydrogen phosphate buffer solution was 0.02mol/L, the reaction time was 16h. Under the optimal conditions, the concentration of GABA reached 2900mg/100g rice bran. The optimal purification conditions of GABA enriched solution also be determined as following: the optimal pH of sample solution was 2.0, the concentration of GABA enriched solution was 2.0mg/mL,concentration of eluting agent was 2.0mol/L. And the final purity of GABA reached 61.25％.关键词
