Abstract

Abstract

Germ-remaining rice Z601 was used as material to accumulate GABA content during germination.A quadratic polynomial model was established for GABA content as a function of four variables which were soaking temperature and time as well as germination temperature and time.The optimum conditions were as follows:soaking temperature at 31℃, soaking time at 13h, germination temperature at 31℃, germination time at 27h.Under the optimum condition, GABA content reached 31.13mg/100g, which was almost 4 times higher than that in the rice which did not germinate.
