Abstract

Lactobacillus plantarum PMO 08 was evaluated as a starter culture for plant-based probiotic beverages. Its viability under various culture conditions and acidification ability in standardized tomato medium, fermentation parameters, and beverage properties were assessed. Lactobacillus plantarum PMO 08 could grow under various culture conditions; there was a high correlation between the incubation time to reach the optimal conditions and the inoculation concentration of lactic acid bacteria (LAB) (r2 = 0.997). Acidity (0.958 ± 0.002%) and LAB count (9.78 ± 0.14 Log10 CFU/mL) were significantly higher when fermented with L. plantarum than with the yogurt starter culture. A survival rate of 96% and 95% in artificial gastric juice and artificial intestinal juice, respectively, indicated that the probiotic requirements were met. The total polyphenol and glutamine content, and antioxidant activity increased after fermentation. The proline content significantly increased in L. plantarum PMO 08- fermented beverage. Thus_, L. plantarum_ PMO 08 is an effective starter culture for non-dairy probiotic beverages whose functional quality may be improved by fermentation.

Keywords: L. plantarum PMO 08; kimchi; non-dairy probiotic beverage; plant-based fermented beverage; probiotic starter culture; tomato juice.
