Germinated Sang Yod Brown Rice as a Novel Prebiotic for Synbiotic Dietary Supplement Development

Abstract

This study aimed to investigate the prebiotic properties of germinated Sang Yod brown rice in supporting the growth of the probiotic bacteria Lactobacillus pentosus GP6. Germinated brown rice was dried, ground into powder, and mixed with De Man Rogosa and Sharpe (MRS) broth at 1%, 3%, and 5%. Bacterial cells were counted at 0, 3, 6, 9, 12, and 24 h after incubation at 37°C. The results showed that the concentration of germinated Sang Yod brown rice powder that exhibited the highest bacterial growth was 3% (10.97 log cfu/ml), followed by 5% (10.85 log cfu/ml) and 1% (10.42 log cfu/ml), respectively. The 3% germinated Sang Yod brown rice powder produced a synbiotic dietary supplement with L. pentosus GP6. The results showed that L. pentosus GP6 survived with 10.00-10.30 log cfu/ml cell numbers at 4°C for 6 months. This study demonstrated that germinated Sang Yod brown rice could be implemented as a prebiotic and component of synbiotic dietary supplement products.
