Wheat germ is a by-product of the wheat milling industry. It constitutes about 2-3% of the wheat grain and contains about 11% oil. The by-products recovered from food processing can be turned into valuable products or at least converted into useful products. On the other hand, it
is possible to convert lipid to monoglyceride and diglyceride by enzymatic ethanolysis. In this study, enzymatic ethanolysis of supercritical carbon dioxide extracted wheat germ oil with Lipozyme TL-IM and Lipozyme RM-IM was investigated for producing diglyceride, monoglyceride and fatty acid ethyl ester and enhancing the function of wheat germ oil. For that, wheat germ oil was extracted by 200bar and 40℃ condition by supercritical carbon dioxide. The enzymatic ethanolysis is carried out in an elenmyer flask containing a mixture of wheat germ oil
and ethanol (99.90%) using 4-5 wt% mobilized lipase as Lipozyme TL-IM and Lipozyme RM-IM and the reaction mixture were incubated at 50-70℃ with 120 rpm shaking. wheat germ oil and extracted oil were compared and analyzed.
