| Abstract: | The development of lipase-catalyzed glycerolysis of oil to synthesize monoglycerides 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. |
