| Abstract: | Lipase-catalyzed synthesis of a new-type of antioxidant in solvent-free system was studied.Using Novozym435 as catalyst,transesterification of ethyl ferulate(EF) with different fatty alcohol to form fatty ferulate in solvent-free system was investigated.According to the yield of transesterification,ethyl ferulate(EF) with oleyl alcohol(OA) was chosen as the optimized substrate.The influences of reaction temperature,the ratio of enzyme to substrate,agitation speed,reaction time,water activity,the molar ratio... |
| Keywords: | ethyl ferulate fatty alcohol fatty ferulate Novozym435 lipase solvent-free system |
