Resumo
Frutas e hortaliças minimamente processadas têm mostrado crescimento expressivo nos últimos anos, em virtude de grandes mudanças no estilo de vida do consumidor, como a conscientização da necessidade de uma dieta alimentar saudável e que cumpra as exigências de segurança alimentar. A cenoura é uma das mais populares, pela sua versatilidade de uso e formas de apresentação ao consumidor. Este trabalho teve como objetivo avaliar a eficiência da etapa de sanitização e o aspecto microbiológico de cenouras minimamente
processadas armazenadas em diferentes embalagens. As hortaliças foram minimamente processadas e avaliadas
microbiologicamente quanto ao teor de coliformes a 35°C, coliformes a 45°C e psicrotróficos. Observou-se que a sanitização da hortaliça foi eficiente, visto que a contagem microbiana para coliformes teve diminuição após o processamento. A embalagem não influenciou no crescimento de microrganismos. A contagem de coliformes estavam dentro dos limites estabelecidos pela legislação. O produto foi considerado seguro até o 7o dia de armazenamento, após esse período a contagem de psicrotróficos foi elevada.
Minimally processed fruits and vegetables have shown significant growth in recent years due to major changes in the consumer's lifestyle, such as awareness of the need for a healthy diet that meets food safety requirements. The carrot is one of the most popular, for its versatility of use and forms of presentation to the consumer. This work aimed to evaluate the efficiency of the sanitization step and the microbiological aspect of minimally processed carrots stored in different packages. The vegetables were minimally processed and evaluated microbiologically for coliform content at 35 °C, coliforms at 45 °C and psychrotrophic. It was observed that the sanitation of the vegetables was efficient, since the microbial count for coliforms decreased after processing. The packaging did not influence the growth of microorganisms. The coliform count was within the limits set by legislation. The product was considered safe until the 7th day of storage, after that period the psychrotrophic count was elevated.
