摘要：This work had as objective the obtention of clarified passion fruit juice by using the microfiltration technique. A step of enzymatic treatment was introduced before microfiltration, aiming to enhance process efficiency by reduction of viscosity and pulp content of the juice. Three different hidrolytic enzymes were tested in three concentration levels. The results didnt demonstrate significant differences in Brix, pH and acidity of the hidrolyzed juice samples in relation to the concentrated juice. Positive effect was observed in the action of the enzymes in the reduction of viscosity and pulp content. The microfiltration was realized in a tubular membrane system with average size of the pore equivalent to 0.3 m and transmembrane pressure of 1.5 bar. The permeate juice was clear, free from pulp and with good micribiological quality. Such results proved the efficiency of microfiltration for clarification and stabilization of fruit juices.
