| 摘 要： | 以糙皮侧耳(Pleurotus ostreatus)下脚料——菇柄为试验材料,利用超声波法提取其中水溶性膳食纤维,采用正交试验L9(34)对菇柄水溶性膳食纤维的提取工艺进行优化.结果表明,菇柄水溶性膳食纤维提取工艺的最佳条件为:超声波时间20 min,超声波功率为450 W,溶剂用量为20 mL/g,提取温度为70℃.该工艺条件下,水溶性膳食纤维粗品SDF得率为11.32％,SDF中可溶性膳食纤维含量为80.68％.

| Abstract: | Orthogonal testing L9(34)] was used to optimize selected parameters affecting the aqueous extraction of soluble dietary fiber(SDF) from Pleurotus ostreatus stipes using ultrasound.The maximal yield of extracted material(11.32%),containing 80.68% SDF,was achieved when 1 g of stipe tissue was suspended in 20 vols of distilled water at 70 ℃ and exposed to ultrasound for 20 min at a power setting of 450 W. |
