摘要: 以黑木耳(Auricularia auricula)的子实体粉粒为原料,研究了其中黑木耳粗多糖(CAAP)的分离提取方法及其产品的溶解性能等特性。以蒸馏水为提取剂,当分离提取的工艺条件为:20~40目的子实体粉粒的料水比为1:15,乙醇与浓缩后物料的体积比为4:1,提取液的水温控制为75℃,每次浸提时间2h,提取次数为5次时,产品的得率较高;采用冷冻干燥工艺制得的CAAP产品的性能优于真空干燥的产品;胰蛋白酶法与Sevage法结合使用脱除蛋白质时,CAAP的纯化效果优于单独使用Sevage法。

Abstract: The optimal processing conditions for the extraction of polysaccharides from Auricularia auricula fruit-body werestudied. Using distilled water as extraction agent was better than dilute alkali or acid. The results showed that: the rate of dryfruit-body powder to water was 1:15, the opitimal rate of alcohol to concentrate liquid was 4:1, the extracting temperature wascontrolled at 75℃ with 2h for each time and total times were 5. The quality of freeze drying CAAP was better than that of vacuumdrying. Combining enzyme deprotein mothod with Sevage method was found better than Sevage deprotein method.
