| 中文摘要: |
| 以棠梨籽为原料，研究超声波-微波协同提取棠梨籽油的最佳工艺，分析其脂肪酸组成。在单因素试验基础上，选择微波时间、超声功率、料液比和超声温度为自变量，以棠梨籽油出油率为响应值，采用响应面分析法，考察超声波-微波协同提取棠梨籽油的最佳工艺；采用气相色谱分析棠梨籽油脂肪酸组成。结果表明，最佳提取工艺条件：液料比为3.45 mL·g-1、超声温度为70.00 ℃、组合时间为超声10 min-微波30.00 s、组合功率为超声120 W-微波480 W，棠梨籽出油率为34.78%。棠梨籽油中脂肪酸组成以不饱和脂肪酸为主，其中油酸24.29%、亚油酸60.94%。本研究为棠梨籽油的进一步开发利用提供了科学依据和技术参考。 |

| The Objective of this study is to optimize ultrasonic-microwave wave synergistic extraction of pyrus betulaefolia punge seed oil and fatty acid composition analysis.On the basis of single-factor test,the response surface methodology was optimize the processing parameters,including microwave time, ultrasonic power, solvent/material ratio and ultrasonic temperature. The oil production rate was chosen as response value,the optimum process was studied by response surface methodology (RSM) . Meanwhile,the fatty acid composition was analyzed by GC. The optimum technological conditions were liquid to material ratio of 3.45 mL·g-1, ultrasonic temperature 70.00 ℃, combination time of ultrasonic 10 min-microwave 30.00 s, combination power of ultrasonic 120 W-microwave 480 W,the oil production rate of pyrus betulaefolia punge seed oil was up to 34.78%. The oil obtained under these conditions was abundant in unsaturated fatty acids,in which the content of oleic acid ,linoleic acid were 24.29% and 60.94% , respectively. This study provides scientific basis and technical reference for the further development and utilization of pyrus betulaefolia punge seed oil. |
