Abstract:  A Study on the clarification of orange juice (Citrus sinensis )by hollow fiber ultrafiltration (UF) was presented in this paper. The experiments mainly investigated effects of operating pressure , temperature, food concentration and food flow rate on the permeate flux; and the retention of nutrient contents in UF juice was determined. The possibity of using UF as a pretreatment step for concentrating by membrane distillation was also studied. The results indicated that UF could be used for the clarification of orange juice , and had no significant effects on the flavor and nutrient contents of the orange juice. The distillate flux of membrane distillation coule be increased by UF pretreatment since UF removed pectins and other solids
