Abstract

In this study, we attempted to produce a probiotic alcoholic beverage from fermented sake cake with lactic acid bacteria. When a 10-fold dilute heat-sterilized sake cake was fermented using Lactobacillus plantarum HOKKAIDO at 30°C for one day, lactic acid bacterial number and pH were 1.8×108 CFU/ml and pH 3.2, respectively. The fermented product also contained 0.21 mg/ml glucose and 7.03 mg/ml lactic acid, so the resulting product was slightly sweet with a strong acid taste. Moreover, we found that the fermented product contained higher ornithine and acquired taurine and citrulline, which are known as functional food materials. In a low-temperature storage test of the fermented product with alcohol for 35 days, it was observed that HOKKAIDO strain existed > 1 + 107 CFU/ml until the presence of 10% alcohol. The results suggest that a probiotic and any new functional low alcoholic beverage can be manufactured from fermented sake cake with lactic acid bacteria.
