摘要
采用单因素实验和正交实验,进行了微波辅助提取松仁多糖的研究,得到了微波辅助提取松仁多糖的最佳工艺条件:料液比为1∶15,微波功率为320W,微波处理时间为5min,浸泡时间为60min。在此工艺条件下,多糖提取率为6.01%。与直接加热提取法进行比较,结果表明,微波辅助提取能大大缩短萃取时间,降低提取剂用量,并能提高松仁多糖产率。
Microwave-assisted extraction （MAE） of pine seed polysaccharides was studied by using single factor experiment and orthogonal method. It was concluded that the optimal condition of extraction is microwave treatment for 5min at power of 320W after marinated 60min,the mass ratio of material to water being 1：15. Under this condition,the yield of polysaccharides is 6.01%. Compared with direct- heating extraction,MAE can shorten the extraction time,reduce the consumption of solvent and improve yield of pine seed polysaccharides.
