Abstract

The aim ofthis study was to verify microbiological quality and the physical-chemical characterization from 21 pasteurized goat milk strains. The Most Probable Number (MPN) of Total (TC) and Fecal coliforms (FC), total bacteria counts, fat, total solid, nonfat sec extract e density were detennined. It was possible to find TC in two strains (9.5%) (0.9 and 110 FCU/mL) and one strain (4.76%) with FC (2.1 FCU/mL). The total bacteriacountsreached a maximum of 2,5 x 106 cfuhnL. Two goat milk strains (9.5%) had density (1034,2 e 1035,8 g/L) higher than admitted. The nonfat sec extract presented variability and one strain (4.76%) presented lower value than admitted. Of the 21 pasteurizado goat milk samplcs analyzed, 14 (66,7%) presented satisfactory standard. All the samples had presented fat above of 3%, that were classified as integral milk. Seven strains were considered unsatisfactory, that didn't respect the criterias of TC and FC (1/7), mesophilic bacteria (5/7), density (2/7) and ESD (117) for pasteurized goat milk.
