Avaliação da qualidade microbiológica de polpas de frutas comercializadas no município de Várzea Grande - MT

Abstract

According IBRAF - the Brazilian Fruit Institute, Brazil is the third largest fruit producer in the world, reaching a mark of 43 million tons per year, contributing 10% of world production. The objective of this research is to evaluate the quality of the final product of frozen fruit pulps marketed in markets of the Várzea Grande / MT region. We analyzed 32 samples of 6 different flavors of 4 most commercialized brands in the Várzea Grande-MT region. Total coliforms and Escherichia coli were determined using the chromogenic / fluorogenic substrate method, (APHA, 2012) and Colony Forming Units of heterotrophic bacteria (CFU / mL). For total coliforms and Escherichia coli the result was absence for all brands. In the analysis of heterotrophic bacteria, only the C-tag obtained a significant increase in relation to the other brands obtained 4.47 logUFC / mL in the passion fruit pulp, brand C obtained 100% Of growth in the analyzed pulps, while the A marks had 50%, B 66,67% and D 66,67% obtained the same percentage of growth, however for heterotrophic bacteria there was a high growth for 3 of the 4 marks Analyzed, indicating faults in the handling, transport and conservation of these products, alerting to hygienic sanitary conditions.
