RUSCHEL, Carla K.; CARVALHO, Heloisa H.; SOUZA, Roberval B. de  y  TONDO, Eduardo C.. Microbiological and physical-chemical quality of orange juices commercialised in public streets of Porto Alegre city. Ciênc. Tecnol. Aliment. [online]. 2001, vol.21, n.1, pp.94-97. ISSN 0101-2061.

The commercialisation of nonpasteurized orange juice has been increased in recent years in Porto Alegre city, in South Brazil. The purpose of this research was to evaluate the quality of this product. Physical-chemical and microbiological analyses were performed in 52 samples of orange juice purchased in the streets of Porto Alegre city. The microbiological analysis demonstrated that 44,23% (n=23) of the samples did not agree with Federal Regulations. All the reproved samples presented inappropriate levels of molds and yeasts. Fecal coliforms were found in 5,7% (n=3) of the samples, while Salmonella Cholerasuis was isolated from one sample. The physical-chemical analysis demonstrated that 89,47% of the samples were in discordance with parameters established by Federal Regulations. Based on the results, good manufacturing practices (GMP), specially on personnel hygienic habits, and equipment sanitization are necessary.

Palabras clave : orange juice; microbiological analysis; physical-chemical analysis.
