文摘
- •
Highest enzyme loading and enzymatic activity were obtained in PLA2-Fe3O4/SiOx-g-P(GMA).
- •
Residual phosphorus content and free fatty acids content were 9.7 mg/kg and 0.84 g/100 g.
- •
PLA2 can hydrolyze Sn-2 ester bond of phospholipids without acyl migration.
- •
The problem of the high free fatty acid content and low efficiency could be solved.
- •
The magnetic immobilized PLA2 still possessed more than 80% of its initial activity.
