| 摘 要： | 对杜氏盐藻油脂的超声波提取工艺进行了研究,采用响应面分析法分析了液固比、超声时间和超声温度对盐藻油脂得率的影响,并建立了相应的预测模型。方差分析的结果表明,液固比、超声温度和超声时间对油脂得率都有显著影响(P<0.005),液固比的二次方项(P<0.005)和超声温度的二次方项(P<0.01)对油脂得率有显著影响,并且超声温度和时间存在交互作用(P<0.05),考虑到提取效率、成本和可行性,利用约束复合形法对结果进行优化,得到的最佳工艺参数为:在选用丙酮为提取溶剂的条件下,液固比29∶1 mL/g、超声时间47 min、超声温度48℃。在最佳工艺参数下,盐藻油脂得率为16.03%,与预测结果相符。

| Abstract: | Technology for ultrasound assisted extraction of oil from Dunaliella salina was investigated.Response surface methodology was used to optimize some operating parameters on the effects of ultrasound assisted extraction of oil from Dunaliella salina on the extracting ratio of oil.Three independent variables tested were ratio of liquid to solid,ultrasonic time,and ultrasonic temperature.The T-test and p-value indicated that quadratic liquid-to-solid ratio(P<0.005),and the three variables(P<0.005),followed by t... |
