Abstract

Macroporous resin was developed to extract sesamin from sesame oil. In order to improve adsorption capacity of macroporous resin, some special compounds were selected to be grafted to macroporous resin. The main factors affecting resin modification were studied and the characteristics of resins were analyzed. High-performance liquid chromatography (HPLC) was used to test the adsorption capacity of resins. Fourier transform infrared spectrometer and Brunauer–Emmett–Teller surface area and pore size analyzer were used to characterize the surface of modified resin. The static and kinetic adsorptions of sesamin on modified resin were studied. Results showed that glycerol was the best grafting compound, and the adsorption ability of macroporous resin increased by 145.16% after modification. The optimum modification condition was the grafting reaction which occurred at 50°C for 24 h using glycerol as the grafting compound and hydrochloric acid as the catalyst.
