Abstract

We investigated the suitability of rice flour for fermented beverage production using various strains of lactic acid bacteria. Fermentation led to a decrease in pH from 5.04-5.17 to 3.74-4.35. At the same time, total acidity increased (1.28-2.59 g/l) due to lactic acid (0.59-2.76 g/l) and acetic acid (0.11-0.30 g/l) production. Fermentation of rice beverages also caused a gradual decrease in glucose and fructose concentration. Lactic acid bacteria proliferated in the first phases of fermentation, and cell counts reached a maximum after 12 h. The highest growth rate (vLAB = 0.44 Log10 CFU/ml/h) was observed in a sample with the culture of Lactobacillus brevis CCM 1815. Viscosity of beverages decreased significantly after 24 h of fermentation. The highest values of sensory parameters were observed in a monoculture of Lactobacillus plantarum CCM 7039 and in a sample with a mixed culture of Lactobacillus plantarum CCM 7039 and Bifidobacterium longum CCM 4990.
