摘要:

为确定益生菌FGM发酵黄芪多糖的最佳提取工艺,本试验以发酵黄芪多糖含量为考察指标,采用响应面法对工艺的提取参数进行优化,并建立回归模型。结果显示,提取时间、提取温度和料液比对发酵黄芪多糖的含量影响显著,并且两两因素间存在一定的交互作用;影响发酵黄芪多糖提取含量的工艺因素按主次顺序排列为:料液比 > 提取温度 > 提取时间;乳酸菌发酵黄芪液多糖提取最佳工艺为:提取时间65 min、提取温度80℃、料液比为1:9,在此条件下,发酵黄芪多糖的含量为6.72 mg/mL。试验证明该工艺可行,可为新兽药开发提供参考。

Abstract:

Response surface method was used to optimize main process parameters for the polysaccharides extractions from Astragalus membranaceus fermented by probiotic FGM strain.A regression model equation was fitted.The results showed that extraction time, extraction temperature and solid-liquid ratio were significant factors on polysaccharide content fermented from Astragalus membranaceus and there was interactive effects between every two factors.Polysaccharide content was significantly affected by solid-liquid ratio,followed by extraction temperature and extraction time.The optimum conditions were found to be that the extraction time was 65 min, extraction temperature was 80℃,solid-liquid ratio was 1:9,and the polysaccharide content was 6.72 mg/mL at this condition.The results showed that the model was practical that could provide a base for exploitation new medicine.
