Production of a fermented organic rice syrup with higher isomalto-oligosaccharide using .

Isomalto-oligosaccharide (IMO) syrup was prepared from organic rice, in which as a starter was inoculated to raise its purity and also produce a fermented rice beverage. Of the five strains of lactic acid bacteria tested, was preferentially selected in terms of a viable cells (7.3 × 10 colony forming unit (CFU/mL) and higher dry cell weight (13 mg/mL). The fermented syrup-based medium did not affect the growth of . As expected, the residual sugar content gradually decreased by 1.34% compared with the initial concentration. It was apparent that the residual sugars but not oligosaccharides were removed during the fermentation period. The production of lactic acid was the highest (8125.78 mg/kg) among the organic acids produced in the fermented IMO syrup.
