Abstract

In this study an automatic germinating system for germinated brown rice (GBR) was developed for accelerating germination and sprouting of brown rice. With the developed germinating system, the effects of anion radiation treatment on germination ratio, sprout growth, color quality and ${\gamma}$-aminobutyric acid (GABA) content of brown rice were investigated. This system can fast produce GBR by controlling the environmental conditions such as ambient temperature, relative humidity, and proper anion radiation. Air-phase germination with intermittent water spraying improved both germination ratio and sprout growth by about 2.2 and 2.3 times, respectively, compared to the conventional water soaking method. Our results strongly suggest that this germinating system that provides air-phase germination with intermittent water spraying and anion radiation can produce germinated brown rice with good color quality, high GABA content, and fast germination ratio as well as sprout growth.
