Effect of Lime Juice on the Bacterial Quality of Zobo Drinks Locally Produced in Nigeria
E. Nwachukwu, O.M. Onovo and C.F. Ezeama

Abstract:
The bacterial quality of zobo drinks locally produced and the effect of lime juice on the bacteria associated with the drinks were investigated. Zobo drinks were obtained from local market and analysed bacteriologically according to standard methods. The total viable counts was 2.79 log10 cfu mL-1 and total coliforms was 2.62 log10 cfu mL-1. Bacteria isolated from zobo drink samples included Staphylococcus aureus, Bacillus subtilis, Lactobacillus sp. Escherichia coli, Pseudomonas aeruginosa, Enterobacter aerogenes, Klebsiella sp. The isolates in decreasing order of occurrence were Staphylococcus aureus (45%), Escherichia coli (40%), Lactobacillus sp. (37%), Enterobacter aerogenes (32%), Pseudomonas aeruginosa (30%), Klebsiella sp. (26%) and Bacillus subtilis (23%). The total coliforms and total viable counts generally decreased in values following treatment of zobo drink samples with lime juice. The study revealed that lime juice can be used to prolong the shelf-life of zobo drinks.
