| Abstract: | Using enzymatic-ultrasonic extraction methods,polysaccharide was extracted from zizyphus jujube mill and the content was determined by phenol-vitriol colorimetry. To investigate the optimal preparation technique of extraction of polysaccharides from zizyphus jujuba mill,in order to cumulate the technical parameters on industrial production. The results showed that the optimal extracting condition extraction time 20 min,buffer ratio 40,pH 5.5,temperature 55 ℃,extracting 2 times,enzyme content 1.5% and the amylose content was 37.13%. The method of extraction appeared to be simple,convenient and efficient. |
