Ferulic acid has obvious antioxidant, scavenging free radicals, anti infection and neuroprotective effects. However, the poor solubility of ferulic acid, which limits its application in the oil based food, medicine, and cosmetics. Several studies have found that the natural antioxidant composition of the modified structure of lipid can significantly improve the application of natural antioxidant components. To model and optimize the reaction conditions of enzymatic esterification of ferulic acid with maize germ oil in solvent system by response surface metodology (RSM) based commercial lipases Lipozyme RM IM. Central composite design was used to design the experiments. The reaction factors investigated were the substrate molar ratio of maize germ oil and ferulic acid ( Sr =4:1~10:1), temperature ( T =60~80°C) and time ( t =20~30h). The yield of of eruloylated fatty acyl structured lipids was selected as response value. All factors investigated positively affected the yield of of eruloylated fatty acyl structured lipids. The optimal reaction conditions were: Sr =8.9, T =76.0°C and t =28.1h, and yield of of eruloylated fatty acyl structured lipids was 59.1% under these conditions. The actual value was in reasonable agreement with the predicted value of 58.8%. The above prepared structured lipids produces low polymer in the frying experiment, and it has high storage stability. RM IM Lipozyme is an effective and specific technique for the synthesis of ferulic acyl fatty acyl group. It can be used in the produced process of feruloylated fatty acyl structured lipids.
