Qualidade do leite de cabra in natura processado em mini-usinas do Médio Sertão e Cariri Paraibano - estudo comparativo.

Abstract

This work had as objective determines and compare the quality of goat milk producted on the middle sertão and cariri paraibano comparing them to each other. It was used the microbiologics parameters (total count of mesophilics, total coliforms, termotolerants coliforms and presence of E. coli), physical-chemical (acidity in degrees Dornic, density, tenor of the fat and extracts dry total and degreased) and biological (detection of antibiotics residues) for determination of your quality. It was observed that the microbiologic quality the mini-plant A and B obteined average for mesophilics count, total coliforms and termotolerants of 2,4·109 UCF/mL and 8,5·109 UCF/mL; 1,9·104 MPN/mL and 4,4·104 MPN/mL; 1,1·102 and 1,5·103 respectively. The E. coli prevalence was of 2% in the plant A and 0,67% for to B. The found physical-chemical parameters went respectively to the plant A and B: acidity 16,66ºD and 15,14ºD; density 1026,82 and 1028,43; fat 4,04% and 3,95%; extract total dry 10,68% and 12,11%; extract degreased dry 6,63% and 8,16%. The antibiotics residues were of 21,3% and 24% for to A and B respectively. Like this, both mini-plants presented similar quality and they need if it pawns in improving the quality of the received product.
