【摘要】 为了更好地开发利用木棉花多糖，研究选取了料液比、提取时间、提取温度3个因素，通过单因素试验和L₉（3³）正交试验，以木棉花多糖提取率为考察指标，优化了木棉花多糖的提取工艺。结果表明：木棉花多糖的最佳提取工艺为料液比1∶30（g/mL）、提取温度70℃、提取时间15 min，在该条件下木棉花的多糖提取率为（11.84±0.12）%。该提取工艺提取率高，重复性好，并且比微波提取成本更低，更适合木棉花多糖提取的工业化生产。更多还原

【Abstract】 For the better development and utilization of Bombax ceiba polysaccharides,the single factor experiment was conducted to investigate the effects of solid-liquid ratio,extraction temperature and extraction time on the extraction rate of B.ceiba polysaccharides,and then the optimal extraction conditions were determined by the L₉（3³） orthogonal experiment.Results showed the optimal extraction conditions were as follows:solid-liquid ratio 1∶30 （g/mL）,extraction temperature 70℃,and extraction time 15 min.Under these conditions,the extration rate of B.ceiba polysaccharides was （11.84±0.12）%.This extraction process is more suitable for industrial production of B.ceiba polysaccharides due to its high extraction rate,good repeatability,and lower cost than microwave extraction.更多还原
