| Abstract: |
| The extraction conditions of fresh pressed oil-tea camellia seed oil from serous fluid of oil-tea camellia seed were optimized by response surface methodology. With solid-liquid ratio, extraction temperature and extraction time as arguments, oil extraction rate as response value, three factors and three levels experimental design and response surface analysis were carried out, and the regression model was founded. The results showed that the fitting of the regression equation was good. The optimal extraction conditions of fresh pressed oil-tea camellia seed oil were obtained as follows: solid-liquid ratio 40∶?10, extraction temperature 90?℃and extraction time 50 min. Under these conditions, the oil extraction rate was 95.9%, and the extraction process had no effect on the acid value and peroxide value of the fresh pressed oil-tea camellia seed oil. |
