Abstract
Local market is full of various fruit juices, which are packed in different packing materials for this purpose as they keep unspoiled for a long period of time, some preservative agents and different methods of pasteurization process to keep these packages uncontaminated. In this study, physicochemical properties (pH, conductivity, density, dissolved oxygen, salinity and TDS) and fungal contamination were measured. For this task mango juices in tetra packs and bottles of 16 companies were purchased from different localities of Karachi city. The following fungal species; Aspergillus candidus, A. fumigate, A. flavus, A. niger, A. wentii, Rhizopus sp., Penicillium sp., Saccchromyces, Curvularia lunata were recorded in mango juice samples of tetra packs whereas none of the fungus was recovered in mango juice samples in plastic bottles. The influence of physico-chemical parameters on fungal species has also been discussed.
