Abstract
This study investigated the changes in chemical components, antioxidant compounds, and activity before (BG) and after germinated (AG) brown rice in order to promote the availability of these beneficial factors. The GABA content of BG and AG brown rice were 0.07~6.61 and 11.13~49.72 mg/100 g, respectively. The ${\alpha}$-amylase activity of AG brown rice was 1.77~70.25 unit/g fold higher than it was in BG brown rice. Total polyphenol and flavonoid contents, which are known to be related to antioxidation, were higher in BG brown rice than in AG brown rice. The total polyphenol contents of BG and AG brown rice were 10.52~36.38 and 11.38~26.33 mg/100 g, and the total flavonoid contents were 3.55~13.39 and 3.52~9.78 mg/100 g, respectively. Also, DPPH radical scavenging activity was 57.64~251.34 and 50.49~213.35 mg TE/100 g, respectively. ABTS radical scavenging activity and total tannin content showed a similar trend to DPPH radical scavenging activity. We expect that this data will be useful in the manufacturing of food products.
