摘要/Abstract

摘要： 采用响应面法对龙眼多糖热水浸提工艺进行了优化。采用3因素3水平的响应面分析法，3因素分别为液料比、提取时间和转速。建立了一个龙眼多糖得率与影响因子的多元二次回归方程，得到龙眼多糖的最佳提取工艺条件：液料比 45，提取时间 4.5 h，转速191 r/min，实际测得的龙眼多糖得率为（0.413± 0.013）%。

Abstract:

Hot-water technique was applied for polysaccharides extraction from dried longan pulp, and the effects of processing parameters on extraction efficiency was optimized using response surface methodology (RSM). Three independent variables were investigated, including the ratio of water to raw material (mL/g), extraction time (min) and rotation rate (r/min). A quadratic polynomial mathematical model with good correlation was constructed and employed to the optimization. The optimiaed extraction conditions were determined as: the ratio of water to raw material as 45, extraction time of 4.5 h, and rotation rate of 191 r/min, under which the experimental extraction yield of crude longan polysaccharides was（0.413±0.013）%.
