Study for Microorganism contaminated of fresh fruit juices

Abstract

Ten samples of various fresh fruit juices were collected which included pomegranate, orange, Apple, Banana, Coconut and raisin Microbiological tests were performed to investigate, the presence of microorganisms.The result showed that all the samples were contaminated with yeasts and moulds and most of them showed contamination with different types of bacteria.The highest contamination with yeast and moulds was found in raisin juice (9.88×102) and the lowest contamination was found in Banana juice (1.46×106).The most common bacteria was found to be staph. aurous and the highest contamination was found in coconut juice (0.22×106), while the lowest contamination was in raisin juice (0.11×106). While both apple and pomegranate juices showed no contamination.The highest E-coli contamination was found in Banana juice (0.49×106) and the lowest contamination was in apple juice (0.40×106). While orange, pomegranate, coconut and raisin juices showed no contamination
