摘要
为了研究饮料专用酵母抽提物中多糖的提取条件及含量,文章通过单因素和响应面试验对饮料专用酵母抽提物(YE-B)中多糖的乙醇浸提工艺条件进行了优化。结果表明,YE-B中多糖的最佳提取工艺参数为乙醇体积分数68%、浸提温度40 ℃、液料比16:1,此时多糖的含量为27.08%,接近响应面预测值,因此响应面优化YE-B的乙醇浸提工艺真实可信。经检测,YE-B含有26.8%的β-葡聚糖及8.70%的甘露寡糖,表明YE-B具有很好的生物活性。
In order to study the extraction conditions and content of polysaccharides in beverage-specific yeast extracts,in this essay the conditions of ethanol extraction of polysaccharides in yeast-specific yeast (YE-B) were optimized by single factor and response surface experiments.The results showed that the optimal extraction process parameters of polysaccharides in YE-B were 68% ethanol volume fraction,40 ℃ extraction temperature,and 16:1 liquid-to-material ratio.At this time,the polysaccharide content was 27.08%,which was close to the predicted value of the response surface,so that the ethanol extraction process of YE-B was true and credible.According to the test,YE-B contains 26.8% beta-glucan and 8.70% manna oligosaccharide,so YE-B has good biological activity.
