Microbiological evaluation of frozen fruit pulps

Ninety-eight frozen pulps samples of eight different flavors commercialized in the city of Palmas, State of Tocantins, Brazil, were submitted to pH and microbiological analysis. The microbiological analysis included counts for total and termotolerant coliforms (MPN.g-1) and the determination of moulds and yeasts (CFU.g-1). The pH was rate was 2.5 and 4.8. Five samples (4.3%) showed coliform contamination and two of them presented E. coli showing values between 0.3 and 0.9 MPN.g-1. 90% of the samples showed levels of moulds and yeast ranging from <10 to 6,2 x 10(4) CFU.g-1. Among them, 29.6% of the samples were considered unacceptable for consumption according to the legislation.
