Abstract :

In order to produce functional MLM-type structured Lipid with maize germ oil in solvent free system was investigated. Six commercial lipases from different sources (Lipozyme RM IM�?¸ Lipozyme TL IM�?¸ Novozym 435�?¸ Lipase AK�?¸ Lipase AY and Newlase F) were compared for their ability to incorporate caprylic acid into the maize germ oil in solvent free system. Of the six lipases that were tested in the initial screening, Lipozyme RM IM from Rhizomucor miehei resulted in the highest incorporation of caprylic acid into maize germ oil. This enzyme was further studied for the effect of mole ratio of oil and caprylic acid, enzyme load, reaction time and reaction temperature on the incorporation of caprylic acid into maize germ oil. Incorporation of caprylic acid was higher when reactions were carried with 12% lipase of the total weight of substrates with a 4:1 mole ratio of caprylic and acidoil, time course and temperature for synthesis MLM-type structured lipids were 16 h and 50oC. Lipase-catalyzed acidolysis of grape seed oil with caprylic acid could produce high quality MLM-type structured lipids in solvent free system.
