响应面法优化亚临界丁烷萃取杏仁油工艺研究

Research of processing optimization of almond oil by subcritical butane using response surface method

摘要: 以新疆主栽杏品种-红心杏仁为研究试材,在一定的操作条件下,采用响应面法对亚临界丁烷萃取杏仁油工艺进行优化。在单因素实验的基础上,采用Box-Behnken设计,运用SAS8.0软件回归分析了萃取时间、萃取温度、料溶比3个因素对杏仁油得率的影响,并对所得杏仁油的质量指标进行测定。结果表明:萃取时间为46min、萃取温度为42℃、料溶比为1∶6.6g/m L,此时,杏仁油的萃取率为88.58%;其质量指标均符合国家标准。

Abstract: Xinjiang apricot cultivars varieties- Red almonds was used as research test material,the response surface method was used in optimizing the extract of almond oil by Subcritical Butane under certain operating conditions.Box- Behnken was designed,SAS8.0 was used in analyzing the effect of extract time,extract temperature,the proportion of dissolved material on almond oil yield.The result showed extract time was 46 min,extract temperature was 42℃,the proportion of materials and solvents was 1 ∶ 6.6g / m L,the extraction rate of almond oil was 88.58%,and its quality indicators are in line with national standards.
