Daftar Isi:
- Ultrafiltration of passion fruit juice using variation thickness of ceramic membrane has been done. The result show that aquades flux value in 25 minutes for membrane 1,5; 2,0; 2,5; 3,0; dan 3,5 mm is 17,0135; 19,1947; 10,9061; 10,9061 dan 4,3624 L/h m2. Whereas passion fruit juice in same time for membrane 1,5; 2,0; 2,5 mm is 8,2886; 5,6712 dan 4,3624 L/h m2. For membrane 3,0 and 3,5 mm it has not been done because flux value are too small that indicate fouling. Physical and chemical properties parameter in ultrafiltration of passion fruit juice obtained for turbidity and colour very different between passion fruit juice before and after ultrafiltration, whereas reducing sugar and vitamin C are not significant different between passion fruit juice before and after ultrafiltration. Determination rejection coefficient value of membrane for turbidity, colour relatively significan whereas for reducing sugar and vitamin C are relatively not significan
