PVA/ Chitosan (CS) composite membrane was studied in this paper
which could be used for enzyme processing of fat and oils. The parameters such as concentration of lipase
pH
and cross-linking agent as well as metal ions
which influence the immobilization of lipase in membrane
were optimized. The immobilized lipase was 0.66 u/cm2 and the recovery of immobilized lipase activity was 24%. The membrane reactor could be used to synthesize monoglyceride (MG) with many batches.
