Outline of Final Research Achievements

On the mechanism of germination acceleration by red onion, we found that plant hormone and cell-wall decomposing enzymes are closely related in it. Furthermore, we clarified that promotion of metabolism, signal transduction, and IAA cause the acceleration of germination by proteome analysis. Pre-germinated brown rice with red onion showed inhibition of hypertension by the increase of GABA, and increase of polyphenol led to the strong anti-oxidation function. Thus, pre-germinated brown rice is promising as a bio-functional food. We measured ORAC and resistant starch of the germinated brown rice with red onion, which showed high resistance to digestion. As it shows inhibitory activity against beta-secretase, it is promising to prevent consumers from diabetes and dementia.
