Microbiological evaluation of sugarcane juice sold at street stands and juice handling conditions in São Carlos, São Paulo, Brazil

Abstract: Fresh sugarcane juice is sold by street vendors without any heat treatment in São Carlos, São Paulo, Brazil. Twenty-four samples of point-of-sale juice were tested by standard methods to determine heterotrophic bacteria, total and thermo-tolerant coliform counts, Salmonella, and parasites in the juice. 25% of samples showed poor sanitary conditions, with thermo-tolerant coliform levels higher than allowed by Brazilian standards. Salmonella spp. and parasites were absent in all samples. Thermo-tolerant coliform… Show more

“…Estima-se que a cana saudável pode conter 10 1 a 10 8 bactérias por grama, sendo as mais frequentes: Flavobacterium, Xanthomonas, Pseudomonas, Enterobacter, Erwinia, Lactobacillus, Leuconostoc, Bacillus e Corynebacterium (Cleto et al, 2009). Entre as leveduras, podem-se citar: Torulopsis, Candida, Saccharomyces, Torula e Pichia (Bruneli, 1986;Silva & Canho, 1990;Kitoko et al, 2004;Oliveira et al, 2006). Baseando-se na literatura e nas análises realizadas com as amostras do caldo de fermentação obtido após o processo fermentativo com o meio natural não estéril, a competição de substrato pelos microrganismos contaminantes e pela cepa Zymomonas ocasionou uma redução no seu crescimento ocasionando e, consequentemente, a ausência do biopolímero.…”
