To obtain the high content of γ- aminobutyric acid of germinated brown rice,germinated brown rice was implemented pulsed light treatment on salt stress.On the basis of single factor experiment,Box- Behnken surface response was used for optimizing technological conditions of germinated brown rice on salt stress accumulated GABA by pulsed light.The experimental results indicated that Sodium glutamate concentration of 2.01 mg / m L,300 J pulse energy,11 cm pulse distance,once / s pulse frequency,31.80 s pulse ...
