摘　　要：以脐橙渣为原料,用碱法制备膳食纤维。在单因素试验的基础上,采用L(934)正交试验对脐橙渣膳食纤维的提取工艺进行研究,确立了最佳工艺条件为:NaOH质量分数8%、浸提温度60℃、浸提时间5h、液料比15∶1。在该条件下膳食纤维提取率达52.8%,其中SDF占25.7%,IDF占27.1%。产品持水力8.59g/g,溶胀力9.67mL/g。Navel orange residue was used as raw material for extraction of dietary fiber （DF） by alkali solution. On the basis of single factor experi- ments, the extraction process of dietary fiber was discussed with L9（34） orthogonal experiments and the optimum parameters were confirmed as fol- lows： NaOH concentration 8%, extraction temperature 60℃, extraction time 5h, ratio of liquid tomaterial 15ml/g. Under these conditions, the extrac- tion rate of dietary fiber was 52.8%, and soluble dietary fiber （SDF） and insoluble dietary fiber （IDF） accounted for 25.7% and 27.1%, respectively. The water-holding capacity and expansive capacity of the product were 8.59g/g and 9.67ml/g, respectively.
