COMPORTAMENTO DO LEITE DE BÚFALA (Bubalus bubalis) DESNATADO E PASTEURIZADO DURANTE O PROCESSO DE ULTRAFILTRAÇÃO

THE BEHAVIOR OF THE SKIMMED AND PASTEURIZED BUFFALO ́S MILK (Bubalus bubalis) DURING THE UL TRAFILTRATION PROCESS The aim of this work was to evaluate the skimmed and pasteurized buffalo’s milk behaviour considering the flow of the permeate (J), the retention percentage (% Rt) and recovery (% Rc) of the components in the retentate during the ultrafiltration process. The average values of the Volumetric Reduction Factor (VRF) and J were 3 and 35 L.h-1.m-2, respectively. The % Rt and % Rc had increased with the VRF growth. The UF of skimmed and pasteurized buffalo’s milk contributed for a greater % Rt of lipids (100.0%) and proteins (94.8%), including the casein (99.6%) and proteins of the milk whey (82.5%) and a greater % Rc of Ca (99.9%), Mg (81.5%) and P (98.2%). KEY-WORDS: BUFFALO’S MILK; ULTRAFILTRATION; RETENTATE; PERMEATE.
