摘要
采用单因素试验和正交试验,进行了超声波辅助提取松仁多糖的研究,得到了超声波辅助提取松仁多糖的最佳工艺条件:脱脂松仁粉100g,水浴温度90℃,料液比1∶45(g∶mL),时间35min,超声功率800W。在此工艺条件下,多糖得率为9.74%。与直接加热提取法进行比较,结果表明,超声波辅助提取能大大缩短提取时间,提高松仁多糖得率。
Ultrasonic extraction of pine seed polysaccharides was studied by using single factor experiment and orthogonal method, It was concluded that the optimal condition of extraction were 100 g degreased pine seed powder, 90℃ extraction temperature, 45：1 （mL： g） solvent to solute weight ratio, 35 min extraction duration, 800 W ultrasonic power. Under this condition, the yield of polysaccharides is 9.74 %. Compared with direct-heating extraction, ultrasonic extraction can shorten the extracting time, and improve yield of pine seed polysaccharides.
