| 其他摘要 | Oil extractions from red pepper seed were performed by supercritical CO2. Three levels Box–Behnken factorial design (BBD) from response surface methodology (RSM) was applied to optimize the main extraction conditions including pressure, temperature and concentration of modifier (ethanol). The optimum conditions were as follows: extraction pressure, 27.17 MPa; extraction temperature, 47.67 °C; and the added concentration of modifier, 8.11 vol. %. Under the optimum conditions, the oil yield of 18.4 % was obtained, which was well matched with the predicted yield. A simple, stable and sensitive method for the simultaneous determination of saturated and unsaturated free fatty acids in extracted oils using 2-(11H-benzo[a]carbazol-11-yl)-ethyl-4-methylbenzenesulfonate (BCETS) as labeling reagent with fluorescence detection has been developed. All of FFAs were found to give a linear response with correlation coefficients of > 0.9991. The detection limits at a signal-to-noise ratio (S/N) of 3 are in the range of 19.06 ？ 41.19 fmol. This method should have powerful potential for the trace analysis of short- and long-chain free fatty acids from edible oils, foodstuff and other complex samples. |
