STUDY ON LOW-ALCOHOL FERMENTED PASSION FRUITS JUICE WITH ADDING PROBIOTICS LACTOBACILLUS PLANTARUM LY-78

Abstract

Fruit probiotic products are increasingly being studied. However, there are not many works which add probiotics to low-alcohol fermented juices, while this drink is expected to grow in the coming years. The purpose of this study was to test the probiotic supplement (Lactobacillus plantarum LY-78) on low-alcohol fermented passion fruit juice. Research results showed that Lactobacillus plantarum LY-78 was resistant to bile salts, acid, antimicrobial, and grew well in low alcohol fermented passion fruits juice with a density of 8 log (CFU/mL) over four weeks at 4 ^oC.
