Abstract: (4436 Views)
Recently, tend to replacing membrane processing to conventional refining of vegetable oil has been developed. Ultrafiltration was conducted by a flat sheet PVDF membrane with two different MWCOs (50 KDa, M116, and 100 KDa, M183) at various temperatures and pressures (25 - 55 ̊C and 2 - 5 bar). Monitoring of the primary and secondary oxidation products showed that the rejection of peroxides was more through the M183 membrane. In contrast, the M116 membrane was more effective in removing the conjugated dienes and carbonyl compounds. Also, results described that membrane processing was efficient at rejection of total polar compounds comparing in conventional refining.
