酶促酯交换桕脂的改性

THE DEN ATURATION OF THE CHINESE VEGETABIE TALLOW WITH ENZYME BY INTERESTERIFICATION

在脂肪酶 Lipozyme 的作用下,将桕脂与硬脂酸甲酯(SME)或硬脂酸甘油酯(SSS)酯交换,可获得一种可可脂类似物.其三甘酯组成与可可脂极为相似,主要三甘酯为 POS 与 SOS(P:棕榈酸;O:油酸;S:硬脂酸)。在对脂肪酶作用原理讨论之后,给出了其在油脂工程中进一步应用的可能性。

The modification of chinese vegetable tallow with enzyme by interes-terification was discribed in this paper.On the effect of Lipase Lipozymethe chinese vegetable tallow would be interesterified with stearic methylester or tristearin,and a product it's composition of triglycerides is sim-ilar with cocoa butter was obtained.The major triglycerides of this pro-duct is POS and SOS(P:palmitic acid;O:oleic acid;S:stearic acid).The possibility of the lipase apply in fat-engineering would be expoundedafter the discussion of the effect of the lipase.
