椪柑籽油超临界提取工艺的优化
Research and optimization on ponkan seed extracting by supercritical CO2 fluid extraction technique
摘要
Abstract
The influences of time, temperature, pressure and the flux of CO2 on the yield of seed oil from its powder with the supercritical CO2 fluid extraction technique were studied according to the Box-Be-hnken central composite experimental design based on the single factor test. Analyzed the mathematical model which established by response surface methodology ( RSM), and the same time, relationships between studied factors and response of Ponkan seed oil extraction yield were described. Based on the canonical analysis, the optimum conditions were obtained as follows: the extraction pressure is 34. 4 Mpa, the flow rate of CO2 25. 8 L/h, the extraction time is 147. 6 min and the temperature 39. 3 °C. Under the optimized extraction conditions, the predictive maximum yield, of seed oil was 45.95% and the average validation value was (45. 12 + 1. 36) % (n = 3) , so the model could be used to predict the extraction results well.关键词
