| Abstract | This research aimed to study the anti-bacterial, anti-glycation, and antioxidant activities of germinated Riceberry rice kefir. Moreover, total phenolic, anthocyanin, and vitamin B1 and B2 contents were analysed. Anti-bacterial activity was examined by the agar well diffusion method. Anti-glycation and antioxidant activities were determined by albumin glycation and DPPH radical scavenging assay, respectively. Total phenolic, anthocyanin and vitamin B1 and B2 contents were analysed by the Folin-Ciocalteu, pH differential, and high-performance liquid chromatography (HPLC) techniques, respectively. The results showed that germinated Riceberry rice kefir inhibited all tested bacteria (Salmonella Typhimurium DMST 562, Staphylococcus aureus DMST 8013, Bacillus cereus DMST 5040 and Escherichia coli DMST 4212). Germinated Riceberry rice kefir exhibited anti-glycation activity of 36.78±2.24% at 25 mg/ml. Besides, antioxidant activity was found with IC50 to 101.68±0.52 µg/ml. Total phenolic, anthocyanin, and vitamin B1 and B2 of germinated Riceberry rice kefir were 16.55±0.81 mg GAE/g, 155.86±1.93 mg CGE/g, 10.25 µg and 11.42 µg, respectively. In conclusion, germinated Riceberry rice kefir displayed biological activities and bioactive compounds that can be useful in functional foods, cosmetics, and pharmaceutical products. |
