Improveγ-Aminobutyric Acid Content by the Germination of Brown Foxtail Millet

Abstract:

Gamma-amino butyric acid（GABA） in brown foxtail millet was improved by germination treatment using response surface methodology. The maximum GABA content of 184.75 mg/hg was obtained at the conditions：soaking temperature 34 ℃，soaking time 12 h，germination temperature 34 ℃，germination time 60 h. The GABA content was 2.76-fold high as that before optimization，and 8.44-fold as that without the treatment of germination. This investigation suggested that the treatment of germination could effectively improve the content of GABA in brown foxtail millet，which provided new insights into the exploitation of foxtail millet.
