Avaliação da qualidade microbiológica do leite UAT integral comercializado em Belo Horizonte

Abstract: Foram analisadas 80 amostras de leite UAT integral de oito marcas comercializadas em Belo Horizonte, entre janeiro e abril de 1999. Foram realizadas contagens de bactérias mesófilas aeróbicas em meio APC e ágar BHI enriquecido com vitamina B12, sendo os resultados comparados aos padrões estabelecidos pelo Regulamento Técnico de Identidade e Qualidade (RTIQ) do Serviço Federal de Inspeção do Ministério da Agricultura e Abastecimento do Brasil. Das 80 amostras analisadas, 33 (41,2%) apresentaram contagem de bact… Show more

“…A common commercial standard is 1 in 10 000 (Robertson, 2003). However, the incidence of non-sterility may be much higher than the spoilage rate if enrichment procedures are used in the analysis (von Boekelman & von Boekelman, 1998;Coelho et al, 2001). The contaminants result from two sources: the survival of heat-resistant spore-formers and post-process contamination.…”

“…Microrganismos esporulados conseguem sobreviver ao processamento UHT e, quando isto ocorre, o aquecimento age como estimulante sobre o crescimento. Sendo assim, a quantidade de esporos presente no leite UHT é proporcional à quantidade de esporos presente no leite cru (COELHO et al, 2001).…”
