Abstract

In the absence of organic solvent, di- and mono-acylglycerol enriched functional oil was produced by lipase-catalyzed glycerolysis in a stirred tank batch reactor. After glycerolysis for 48 hr, functional oil consisted of $47.1\%\;TAG,\;33.6\%\;DAG,\;and\;18.7\%$ MAG. In MAG and DAG, docosahexaenoic acid was found as $10.7\%\;and\;8.1\%$, respectively. During the reaction, total tocopherol content decreased, and $0.065\%$ tocopherols were existed in the functional oil produced after 48hr reaction.
