摘要

Abstract

The structured lipids are produced through sn-1

3-specific interesterification of soybean oil with medium-chain triacylglycerol (MCT) in continuous reactions catalyzed by

Thermomyces lanuginose

lipase (Lipozyme TL IM). Cheap Lipozyme TL IM presents similar interesterification degree (ID)

sn-1

3-specificity and residual activity as expensive

Rhizomucor miehei

in batch reactions. In packed-bed interesterification of soybean oil with MCT catalyzed by LipozymeTL IM

the residence time has a significant effect on ID

while temperature has a small effect at 45-70℃. The sn-1

3-specificity of Lipozyme TL IM is not satisfactory when reaction temperature is higher than 60℃. The optimal residence time and temperature are 30-40 min and 55℃

respectively. Among the solvents

including acetone

isopropanol

tert

-butanol

and isobutanol

used to recover the activity of the used Lipozyme TL IM

acetone is the most suitable one than the other solvents.
