Optimization of Determination γ-Aminobutyric Acid in Brown Rice by Colorimetric Method
摘要
Abstract
To optimize method for determining γ-aminobutyric acid content in rice by colorimetric method and establish a simple,rapid and accurate brown rice GABA determination system.[Method] Based on Berthlot chromogenic reaction,determination of γ-aminobutyric acid content in rice by colorimetric method was optimized from determination wavelength,time,phenol,sodium hypochlorite and brown rice dosage.[Result] Theoptimum conditions were:wavelength 630 nm,5% phenol solution 3.4 ml,available chlorine 7% sodium hypochlorite solution 1.5 ml,determination time 60-180 min.the optimum rice dosage 1.2 ml.[Conclusion] The system is simple,rapid,economy and accurate in determining γ-aminobutyric acid content in rice,which can provide reference for screening and breeding GABA enrichment rice variety.关键词
