| 摘 要： | 以杨梅渣为原料,连续提取水溶性和不溶性膳食纤维,在单因素试验基础上,通过正交试验优化提取工艺条件。试验表明,适宜水溶性膳食纤维提取工艺为:以柠檬酸为浸提剂,料液比(g∶mL)1∶10,pH值2.0,90℃提取75 min,在此条件下提取率达58.62%。适宜的不溶性膳食纤维提取工艺为:料液比(g∶mL)1∶12.5,pH值2.5,60℃提取90 m in,在此条件下提取率达61.25%。所制备的不溶性膳食纤维持水力为570.6%、溶胀性为6.5 mL/g,功能特性良好、生理活性突出。 |
| 关 键 词： | 杨梅渣 水溶性膳食纤维 不溶性膳食纤维 提取工艺 参数优化 |

| Abstract: | Myrica rubra was the material,continuous extraction method for both water soluble dietary fiber and water insoluble dietary fiber was established.The extraction technology was optimized by orthogonal test.The optimal conditions for extracting water soluble dietary fiber were:using citric acid as diffusion solvent,Myrica rubra to liquor ratio 1∶10,pH 2.0 under 90℃ for 75 min.The extraction yield reached up to 58.62%.The optimal conditions for extracting water insoluble dietary fiber were: Myrica rubra to liquor ratio 1∶12.5,pH 2.5 under 60℃ for 90min,the extraction yield was up to 61.25%.The water holding capability and hydration capability of water insoluble dietary fiber obtained in the experiment was 570.6% and 6.5 mL/g respectively.The products had better functional properties and excellent physiological activities. |
| Keywords: | marc of Arbutus water soluble dietary fiber water insoluble dietary fiber extraction technology parameter optimization |
