Abstract

Microbiological and physical-chemical analysis were performed on 1,038 samples of whole milk pasteurized by long-time low temperature process in rural properties from the Goiás State. The results showed that 8.19% of samples were out of the standard set by the Brazilian legislation for mesophylic aerobic microorganisms count, 15.13% for NMP of total coliform determination and 13.29% for NMP of fecal coliform. In relation to physical-chemical analysis, acidity and freezing-point tests showed high number of samples out of the standard set by the Brazilian legislation, 12.24% and 17.34% respectively. Alkaline phosphatase enzyme was present in 5.2% of the samples and peroxidase absent in 7.41%, showing inadequate control of the pasteurization process.

KEY-WORDS: Milk; low pasteurization; mini-dairies.
