中文摘要:
      目的 研究采用超声波-微波协同法萃取沙棘籽油的工艺条件,及对沙棘籽油脂肪酸组成的影响。方法 选择溶剂种类、萃取时间、液料比、超声波功率、微波功率、萃取温度等6个因素进行单因素试验。在单因素试验的基础上,选择正己烷为萃取溶剂,以提取率为响应值,选择萃取时间、液料比、超声波功率、萃取温度等4个因素进行响应面优化试验。对此条件下得到的沙棘籽油和超临界CO2法萃取得到的沙棘籽油中的脂肪酸组成成分进行分析。结果 得到了超声波-微波协同法萃取沙棘籽油的最佳工艺条件,萃取时间为22 min,液料比值为9 mL/g,超声波功率为628 W,微波功率为200 W,萃取温度为57 ℃,在此条件下沙棘籽油的提取率可达13.97%。超声波-微波协同法萃取得到的沙棘籽油,其不饱和脂肪酸质量分数高达88.93%,最高的为亚油酸(39.60%),其次为亚麻酸(32.60%)。结论 超声波-微波协同萃取法是一种提取沙棘籽油的有效方法。
英文摘要:
      The paper aims to study process conditions of ultrasonic-microwave synergistic extraction of sea buckthorn seed oil and its influences on the fatty acid composition of the sea buckthorn seed oil. Single factor test was carried out by selecting six factors: solvent type, extraction time, liquid-solid ratio, ultrasonic power, microwave power and extraction temperature. Based on the single factor test, N-hexane was selected as the extraction solvent, and the extraction rate was taken as the response value. Four factors of extraction time, liquid-solid ratio, ultrasonic power and extraction temperature were used to carry out response surface optimization experiment. The fatty acid composition of sea buckthorn seed oil extracted under these conditions and extracted by supercritical carbon dioxide extraction method was analyzed. The optimal extraction conditions were determined as follows: extraction time was 22 min, liquid-solid ratio was 9 mL/g, ultrasonic power was 628 W, microwave power was 200 W, extraction temperature was 57 ℃. Under these conditions, the extraction rate of sea buckthorn seed oil could reach 13.97%. The analysis of fatty acid composition of sea buckthorn seed oil extracted by ultrasonic-microwave synergistic method showed that the content of unsaturated fatty acid was as high as 88.93%, the highest content was linoleic acid, which was 39.60%; followed by linolenic acid, which was 32.60%. Therefore, the ultrasonic-microwave synergistic extraction is an effective method for extracting sea buckthorn seed oil.
