| Abstract: | The cleaner production extraction technology was studied by orthogonal test design and application of membrane separation technology.The results showed optimum extract conditions were that the extraction temperature was 40 ℃,the extraction time was 0.5 h,and the ratio of material to solvent was 1：3.Then by microfiltration N100 and nanofiltration DLC the concentrated retention rate of polysaccharides was 94.5%,and the purity rate was 67.5%.Enterprises using the cleaner production process can reduce costs and greatly improve economic efficiency. |
