In this study conditions of refinement of clarified sugarcane juice including temperature at 3 levels (50, 60 and 70 °C) and pressure at 4 levels (0, 0.5, 1 and 1.5 bars) by micro-filtration membrane technology was investigated. The raw sugarcane juice primarily was pre-filtrated with lime and then the obtained juice (clarified juice) processed by ceramic micro-filter membrane (0.2 micrometer). Investigated characteristics were included purity, turbidity and color. The results shows that the effects of different conditions of process with micro-filtration in studied temperatures and pressures on reduction of turbidity and color were significant at probably < 1% and probably < 5% respectively. Finally, 70 °C temperature and 1.5 bar pressure were determinate as optimum conditions for ceramic micro-filtration. Membrane process at 70 °C and 1.5 bars reduced turbidity and color of clarified juice 56.25% and 6.49% respectively and increased 0.87 units of purity.
