| 中文摘要: |
| 采用超声法提取胡麻籽壳多糖。在单因素试验的基础上，采用四因素三水平响应面分析法，以多糖得率为响应值，优化提取工艺条件，并将超声提取法与热水浸提法进行比较。结果表明：超声提取胡麻籽壳多糖的最佳工艺条件为超声功率80 W、超声温度56℃、液固比49∶1、超声时间21 min、提取次数2次，在此条件下胡麻籽壳多糖得率为2.70%；与热水浸提法相比，超声提取法能耗低、得率高，且提取时间短。 |
| 英文摘要: |
| Polysaccharide was extracted from flaxseed shell by ultrasound-assisted extraction method. Based on single factor experiment, with the yield of polysaccharide as response value, the extraction conditions were optimized by four factors and three levels response surface methodology. The ultrasound-assisted extraction method was compared with hot water extraction method. The results showed that the optimal extraction conditions of polysaccharide from flaxseed shell were determined as follows: ultrasonic power 80 W, ultrasonic temperature 56℃，liquid-solid ratio 49∶1, ultrasonic time 21 min and extraction times twice. Under these conditions, the yield of polysaccharide from flaxseed shell was 2.70%. Compared with hot water extraction method, ultrasound-assisted extraction method had advantages of low energy consumption, high yield, and short extraction time. |
