Abstract
Structured lipid (SL) was synthesized by enzymatic interesterification of algae oil and corn oil in stirred tank batch reactor, The reaction, performed for 15hr at $65^{\circ}C$, was catalyzed by sn-1,3-specific lipase RM IM from Rhizonucor miehei without organic solvent. DHA, oleic acid, and linoleic acid contents of SL were 14.9, 17.3, and 31.8 mol%, respectively. ${\alpha}-,\;{\gamma}-,\;and\;{\delta}-tocopherol$ contents and physiochemical property of SL were evaluated. During 15 hr reaction, most reaction occurred within 6 hr, and highest relative production rate was observed between 3 to 6 hr.
