In this study, an MDEL/TiO2 photocatalyst hybrid system was applied to the production of low molecular weight gelatin. The molecular weight of produed gelatin decreased with increasing microwave intensity and increasing treatment time. The abscission of the chemical bonds between the con- stituents of gelatin by photocatalytic reaction did not alter the characteristics of gelatin. Formation of any by-products due to side reaction was not observed. It is suggested that gelatin was depolymerized by hydroxyl radicals produced during the MDEL/TiO2 photochemical reaction.
在本研究中，将一种MDEL/TiO₂光催化剂混合体系应用于低分子量明胶的制备。所制备明胶的分子量随微波强度的增加和处理时间的延长而降低。光催化反应使明胶成分之间的化学键断裂，但并未改变明胶的特性。未观察到因副反应形成任何副产物。这表明明胶是通过MDEL/TiO₂光化学反应过程中产生的羟基自由基解聚的。
