中文摘要: 以新鲜芦笋修整后产生的老根茎部分下脚料为主要研究对象,采用水浴浸提-超声波辅助法提取芦笋下脚料多糖,设计单因素试验,分别研究液料比、超声时间、超声功率、浸提温度、浸提时间、醇沉浓度对芦笋下脚料中多糖提取率的影响。根据单因素试验结果,设计响应面试验,优化芦笋下脚料多糖的提取工艺。结果表明,芦笋下脚料多糖的最佳提取工艺为液料比32∶1(mL/g)、超声时间27 min、超声功率300 W、浸提温度87 ℃、浸提时间104 min、醇沉浓度95%,该提取条件下,多糖提取率为(6.26±0.06)%。
Abstract:The ultrasound-assisted water bath extraction method was employed to extract polysaccharides from the scraps(old roots and stems)of fresh asparagus.Single factor tests were carried out to study the effects of liquid-to-solid ratio,ultrasonic time,ultrasonic power,extraction temperature,extraction time,and concentration of alcohol for precipitation on the extraction rate of polysaccharides from asparagus scraps.According to the results of single factor tests,a four-factor response surface test was designed to optimize the extraction process.The results showed that the optimal extraction conditions were as follows:liquid-to-solid ratio of 32∶1(mL/g),ultrasonic time of 27 min,ultrasonic power of 300 W,extraction at 87 ℃for 104 min,and alcohol concentration of 95%.Under these conditions,the extraction rate of polysaccharides reached(6.26±0.06)%.
