| Abstract: |
| The preparation process of oil-tea camellia seed oil added with lycopene and the effects of lycopene and other antioxidants on the oxidative stability index（OSI）of oil-tea camellia seed oil were studied.The influences of lycopene dosage，dissolution time，dissolution temperature on the mass concentration of lycopene in oil-tea camellia seed oil added with lycopene were studied by single factor experiment. With mass concentration of lycopene as response value，the optimal process conditions were obtained by response surface methodology as follows：25 g of oil-tea camellia seed oil，lycopene dosage 26 mg（0.104%），dissolution time 8 h，dissolution temperature 63〖KG-*8〗℃.Under these conditions，the mass concentration of lycopene in oil-tea camellia seed oil reached 30.26 μg/mL，which was close to the predicted value.〖JP2〗The study showed that 0.104% of lycopene had good antioxidant effect on oil-tea camellia seed oil，and its antioxidant capacity was lower than that of 0.02%TBHQ and similar to that of 0.02%PG. |
