| 摘 要： | 探讨了超声波协同超微粉技术辅助酸法提取黑木耳果胶的工艺条件。分别考察了超声波辐射强度、液料比、温度、pH值及提取时间等因素对果胶得率的影响,并以此为基础用正交法优化提取黑木耳果胶的工艺参数。结果表明,采用此法从黑木耳中提取果胶的适宜工艺条件为超声波辐射强度70 W/kg、液料质量比40∶1、温度70℃、pH值3.0、提取时间60 mim。在此条件下,木耳果胶得率可达35.45%,与其他方法相比,果胶得率最高。 |

| Abstract: | The technique of extracting auricularia pectin by acid method coupled by ultrasound wave and ultrafine powder is researched.Based on ultrasound intensity,liquid-solid ratio,extracting temperature and time on auricularia pectin yield and extracting conditions are optimized by orthogonal experimental design.The experiment shows that the optimal extracting conditions are：ultrasound intensity 70 W/kg,liquid-solid ratio 40∶1,extracting temperature 70 ℃,pH 3.0 and extracting time 60 min.Under these conditions,auricularia pectin yield can reach 35.45%,better than other extracting methods. |
| Keywords: | ultrasound wave ultrafine powder technique auricularia pectin extracting condition |
