Abstract
The Present study was to isolate the coliforms from street vented and packed fruit juices from different area of Thrissur city. Four mentor fruit juices and four packed fruit juices were examined for the presence of coliforms. Coliforms were detected in two samples Apple juice and pineapple juice with MPN index of 140+and 140+ which were further detected as E coli, Klebsiella spp, Enterobacter spp, Enterococci spp. The highest pH was recorded in apple juice (street vented: 4.86, packed fruit juice: 3.10) and the lowest pH in grape juice (street vented: 2.55, packed fruit juice: 1.45). The highest titratable acidity was recorded in grape juice (street vented: 13.5%, packed fruit juice: 16.5%) and the lowest pH in apple juice (street vented: 4.02%, packed fruit juice: 10.85%). Drug resistance among the isolated was found against Amikacin, Ampicillin, Cefixime, and Cefotaxime. Overall study demonstrates that the quality of fresh juices was unsatisfactory compared to packed juices. Hence the products need to be microbiologically controlled in order to ensure the overall health safety.
