Enzymatic Degumming of Arachidonic Acid Oil Using Immobilized Phospholipase A1 on Hollow Double-Layer Mesoporous Silica Nanoparticles
Abstract
This study explores the application of immobilized phospholipase A1 (PLA1) on hollow double-layer mesoporous silica nanoparticles (PLA1@NH2/C8-HdlMS) for the degumming of crude arachidonic acid (ARA) oil for the first time. The immobilized enzyme was comprehensively characterized, and the reaction conditions were optimized via single-factor experiments. Under the optimized conditions (enzyme dosage 0.3% w/w, 35 °C, water addition 3%, and reaction time 90 min), PLA1@NH2/C8-HdlMS achieved a remarkable phosphorus removal rate of 97.9%, reducing the phosphorus content from 441.21 mg/kg to 9.29 mg/kg in 90 min (well below the food-grade standard of
