Mesophilic bacteria after UV treatment was lowered in a range of -0.20 to -0.62 log CFU/mL and UV treatment at a flow rate of 0.4 L/min showed the maximum reduction, although this condition did not result in a significant number (p>0.05) when compared to a control beverage. Meanwhile, decrease in yeast and mold after UV treatment was found in a range of -0.10 to -0.75 log CFU/mL.Yeast and mold present in the black jasmine rice pericarp beverage were also insignificantly (p>0.05) decreased after UV treatment at a flow rate of 0.4 L/min. Since microbial contaminants remained in the beverage treated at this conditionwere 4.51 log CFU/mL for mesophilic bacteria and 2.06 log CFU/mL for yeast and mold, multiple times of UV radiation are recommended forthe effective disinfection of the black jasmine rice pericarp beverage.
