超临界CO_2中脂肪酶催化甘油解制备单甘酯的研究进展

Research progress on preparation of monoglycerides by lipase-catalyzed glycerolysis in supercritical carbon dioxide

论述了超临界CO2条件下脂肪酶催化甘油解制备单甘酯的研究进展,并从反应温度、压力、含水量、底物比例、脂肪酶活性等方面对反应的影响进行了探讨。此法具有反应温度低,产品色泽好,无溶剂残留,操作步骤大大简化等优点,有望成为食品用单甘酯最有潜力的生产方法。

The development of lipase - catalyzed glycerolysis of oil to synthesize monoglyeerides in supercritical carbon dioxide was discussed. The effects of reaction temperature, pressure, water content, substrate ratio and activity of lipase on reaction were analyzed. This method had several advantages, such as lower reaction temperature, better color of the product, no solvent residues and simpler procedures, so it would be a potential method to produce food grade monoglycerides.
