| Abstract | Fruit juices were found to be a good medium for the growth of probiotic Lactobacillus
bacteria vary on their natural components. Pineapple juice was found to be better source
than guava, orange and tomato juices for the growth and survival of probiotic. Multistrain
of Lactobacillus is significantly more effective than using monostrain in pathogen
treatment. Doses of 109 cfu/ml of probiotic bacteria showed good inhibitory effect was on
all four pathogen studied namely Bacillus cereus, E. coli 0157:H7, Salmonella
typhimurium and Listeria cytogenes. However, one should take care in the choice of
multistrain probiotics as they have complicated interactions between them. In fruit juice
medium with high carbon sources, Lactobacillus continued to growth during storage time
and survival was 92% after 1 month of storage in low pH condition. However, this
fermentation can affect the sensory quality of the final product. Differences in sour taste
and fermentation flavor were found in the probiotic. However, overall they were found to
be acceptable. |
