| Abstract: | Three commercially produced fruit juices namely Oranges, Pineapple and Blackcurrant were purchased from open market in Ibadan Metropolis in Oyo State, Nigeria to examine their quality parameters. Physico-chemical and Microbiological examinations were carried out on these three fruit juices. The results obtained from physico-chemical analysis showed that orange juice had the highest pH value of 3.15 followed by pineapple with moderate pH value of 2.87 while the blackcurrant had the lowest pH value of 2.28. The total titratable acidity of all the samples was also determined with the blackcurrant having the highest total titratable acidity content of 0.63g/100g and followed by pineapple with 0.55g/100g while orange juice had the lowest value of 0.19g/100g. The Microbiological examination however, revealed elevated level of coliform counts. All the three samples had coliform counts ranging between 11 and 14 MPN/100ml with orange juice having the highest coliform count. Other bacteria species found in the samples include Bacillus spp, Escherichia coli, Staphylococcus aureaus, Streptococcus spp and Salmonella spp, Enterobacter spp, Shigella spp, Lactobacillus planetarium, L. brevis and L. perulens.Only four fungal species were isolated and identified. These were Aspergillus niger, Rhizopus stolonifer, Saccharomyces cereviceae, Ochrocosis gallopova, A. flavin and A. glaucus. The presence of coliform in all the three fruit juices showed the possibility of faecal contamination which is of serious concern from the public health point of view. It is therefore suggested that the possible source(s) of contamination need(s) need to be examined in order to protect the poor consumer from the danger of food poisoning and food borne-infection. |
