The ability of a number of mesoporous silica materials (SBA-15, SBA-3, and MCM-48) to immobilize polyphenol oxidase (PPO) at different pH has been tested. Pore size and volume are the structural characteristics with higher influence on the PPO immobilization. Mesoropous material SBA-15 adsorbs a larger quantity of PPO at pH 4.00 and offers an inhibition of enzymatic activity close the 50% in apple extracts.
已经测试了多种介孔二氧化硅材料（SBA - 15、SBA - 3和MCM - 48）在不同pH值下固定多酚氧化酶（PPO）的能力。孔径和孔体积是对PPO固定化影响较大的结构特征。介孔材料SBA - 15在pH 4.00时吸附大量的PPO，并在苹果提取物中使酶活性抑制接近50%。
