A reactive calcium oxide (CaO) catalyst for catalytic applications is disclosed. The catalyst comprises calcium oxide particles exhibiting rod-like and dumbbell-shaped morphologies and particle characteristics associated with enhanced catalytic activity in monolaurin synthesis. The catalyst possesses reduced particle agglomeration and increased accessible surface area relative to calcium oxide materials produced under non-optimized calcination conditions. In certain embodiments, the catalyst exhibits an average particle size in the nanometer range suitable for glycerolysis reactions. The reactive calcium oxide catalyst may be derived from thermal decomposition of calcium hydroxide precursor material and is suitable for use in monolaurin production and related catalytic processes.

The application discloses a kind of metal organic framework ZIF-8 fixed enzyme and its preparation method and application in preparation of diglyceride, to provide a kind of can effectively improve enzyme stability and the reuse of fixed enzyme, with the characteristics of simple operation, mild condition, can effectively promote edible oil preparation rich in diglyceride component edible oil while retaining enzyme activity, its prepared diglyceride edible oil byproduct is less, active ingredient is higher;Its technical scheme is that aspergillus niger lipase is added to zinc nitrate solution, is uniformly dispersed, then, slowly 2-methylimidazole solution is added, uniform speed stirring 60min, stationary 20min, the product is centrifuged, washed, freeze-dried to obtain fixed enzyme;Then raw material oil and glycerol are mixed, emulsified, then ZIF-8 fixed enzyme is added, glycerolysis reaction is carried out at 40~70℃ for 2~12h, after reaction, fixed enzyme is centrifuged, liquid is purified by molecular distillation, and DAG-rich edible oil is obtained;It is related to food technology field.
