摘要
为寻求板栗多糖提取的新工艺,以"燕龙"板栗为原料,采用加压溶剂萃取技术提取其多糖,通过单因素试验和正交试验得出加压溶剂萃取技术的最佳工艺参数,并与热水提取、微波提取、酸提取、超声波提取多糖等提取方法进行比较,确定了提取板栗多糖的最佳工艺参数。结果表明,用加压溶剂萃取法提取板栗多糖的最佳工艺参数为:萃取温度70℃,静态萃取时间8 min,萃取压力6 MPa,循环次数2次。在此最佳工艺参数下多糖的提取率达20.14%,用加压溶剂萃取法提取板栗多糖优于其它4种提取方法。
In order to study the new technology of polysaccharide extraction in Chinese chestnut, taking Yanlong chestnut as materials, polysaccharide was extracted by using pressurized solvent extraction （APLE） technology. The optimum extraction conditions of polysaccharide in Chinese chestnut were obtained by single-factor test and orthogonal test. The technology is compared with hot water-assisted extraction, microwave-assisted extraction, acid-assisted extraction and ultrasound-assisted extraction. The results show that the optimum extraction conditions are the extraction temperature of 70 ~C, static extraction time of 8 minutes and extraction pressure of 6 MPa with two cycles. Under these conditions, extraction rate of polysaccharide is up to 20.14%. Pressurized solvent extraction polysaccharide method is supper to the other four methods.
