摘要
单脂肪酸甘油酯(单甘酯)的酶法合成工艺中最具有工业化前景的当属固体相油脂甘油解。彭立风、谭天伟[1～2]以猪胰脂肪酶固相催化牛油、棕榈油甘油解合成单甘酯,甘油与油脂摩尔比为2～4∶1,最佳反应温度下反应24ｈ后单甘酯含量最高分别达1951%和2417%,将反应物于更低温度下...
Enzymatic glycerolysis of palm oil was studied in solid state with a lipase from Pseudomonus fluorescens as catalyst.The influences of molar ratio of glycerol to oil,reaction temperatures and temperature control on the accumulation of monoglyceriods in reaction mixtures were investigated.The suitable initial reaction temperature should be the minimum co melting point of reactants.The monoglycerides contents in equilibrium state were approximately 30% at 48℃ or higher.An increment of 13% of monoglycerides content was obtained under the optimum temperature programming comparing with the normal equilibrium state.
