| 摘 要： | 紫菜多糖具有多种生理活性,研究其提取工艺具有重要意义.采用微波辅助提取技术和间断式微波辐射加热方法,探索了紫菜粗多糖的提取新工艺.试验研究了不同的微波功率、处理时间、料液比对紫菜多糖提取率的影响.在单因素试验的基础上,通过L9(3 3)正交试验优化了提取条件,取得了微波辅助浸提紫菜多糖的最佳工艺参数,即微波功率120W、提取时间8min、料液比1:30,在此条件下,紫菜多糖提取率为8.478%.

| Abstract: | Taking into consideration that polysaccharides from Porphyra haitanensis have various physiological functions,it's important to have a study on the technology of extracting them. By microwave-assisted extraction and intermittent microwave radiation heating,the new technology of obtaining Porphyra haitanensis polysaccharides was studied. The effects of 3 factors (microwave power,treatment time and solid-to-liquid ratio) on the extraction rate of polysaccharides were investigated. On the basis of single-facto... |
