| Abstract: | The synthesis technology of medium-chain monoglycerides from camphor tree seed kernel oil and glycerol catalyzed by lipase from porcine pancreas was studied.The effect of reaction time,enzyme dosage,molar ratio of glycerol to camphor tree seed kernel oil,initial water dosage and reaction temperature on the yield of medium-chain monoglycerides was investigated.The optimal synthesis conditions were as follows:oil dosage 10 mL,reaction temperature 47℃,enzyme dosage 220 mg,molar ratio of glycerol to camphor tree seed kernel oil 4.3∶1,initial water dosage 35 μL,and reaction time 30 h.Under the optimal conditions,the content of medium-chain monoglycerides in product reached 53.42%±0.05%. |
