Fresh-cut fruits should present characteristics of freshness, convenience and safe adequate to consumer. This work was intended to evaluate the quality of 'fresh-cui fruit salads and papaya purchased on the local marketplace of Lavras - MG during the four seasons of the year. Physical, physicochemical and chemical (pH, titrable acidity, soluble solids, firmness, L*, a* e b* values ) and microbiologic analyses( coliforms at 37 and 45°C, Escherichia coli, Salmonella, estafilococos coagulase positive, filamentous fungi and yeasts and aerobic psychrotrophic microorganism) were performed at the date of collection of the samples and three days after refrigerated storage at 5°e. According to the results obtained, the seasons of the year influenced the physical, physicochemical and chemical characteristics of fresh-cut papaya and of fruits salad and these presented deviations in their quality in the different seasons studied due to the presence of both Salmonella and coliforms at 45°C below the standards established by the Brazilian legislation and to the high indices of coliforms at 37°C, Escherichia coli, filamentous fungi and yeasts, psychrotrophic aerobic micro-organisms and estafilococos coagulase positive, fruit salads were unfit for human consumption. The fresh-cut papayas were fit for human consumption due to the low indices of microbiologic contamination, meeting the standards of the Brazilian legislation. Coliforms at 37°C and total count of psychrotrophic aerobic microorganisms in FC fruit salad and papaya presented significant growth in the storage at 5°e. Summer determine increased microbiologic contamination in FC fruit salads and papaya. (AU)
