分子蒸馏法提取南瓜籽油脚中VEOA北大核心CSCDCSTPCD
Extraction of VE from Pumpkin Seed Oil Sediment by Molecular Distillation
采用响应面试验设计,以温度、真空度、刮板速度为试验因素,以VE得率为响应值,建立数学模型,优化分子蒸馏法提取南瓜籽油脚中VE的工艺条件。结果表明,最佳提取条件为温度220.26℃、真空度0.11mbar、刮板速度649.3r/min。在此条件下,VE得率的模型的预测值83.31%,验证实验得到的VE得率为84.25%。所得回归模型拟合情况良好,达到设计要求。
Response surface methodology was used to optimize VE extraction from pumpkin seed oil sediment. A mathematical model for VE yield as a function of extraction temperature, vacuum degree and scraper speed was built. The optimal extraction conditions were extraction temperature of 220.26℃, vacuum degree of 0.11 mbar and scraper speed of 649.3 r/min. Under these extraction conditions, the predicted extraction rate of VE was 83.31%, which was close to the a…查看全部>>
