Controle microbiológico da vida de prateleira de ricota cremosa Microbiological assessment of creamy ricota during shelf-life

Abstract

Desenvolveu-se este estudo com a finalidade de verificar alguns microrganismos indicadores de contaminação e deterioradores em ricota cremosa durante sua vida de prateleira. No controle microbiológico do produto observaram-se os seguintes resultados: The occurrence of spoiler microrganisms in creamy ricotta during its shelf-life was assessed. The results showed the following contamination levels: < 0.3 MPN/g of coliforms, < 1.0 x 10² CFU/g of coagulase producing Staphylococcus and total aerobic mesofilic counts of between 2.0 x 10² and 2.45 x 10(4) CFU/g. The aerobic mesofilic counts decreased with storage time, with the samples being kept during twenty days under refrigerating condition (7 ºC). The results of creamy ricotta microbiological assessment showed satisfactory hygienical-sanitary conditions.
