[Objective] In this paper, water-insoluble dietary fiber from yacon pomace was prepared by using alkali solution method. It could open new avenues for the comprehensive utilization of byproducts and provide new material sources for the production of water-insoluble dietary fiber. [Method]With alkaline solution amount, alkali treatment temperature and alkali treatment time as effect factors, on the basis of single factor test, the orthogonal test was taken to study the optimum extraction technology of water-insoluble dietary fiber from yacon pomace. [Result]The effects of three factors on water-insoluble dietary fiber content in order was alkaline solution amount>alkali treatment time>alkali treatment temperature. [Conclusion]The optimum extraction technology of water-insoluble dietary fiber from yacon pomace was alkaline solution amount of 2.0 ml/g,alkali treatment time was 60 min, alkali treatment temperature was 40 ℃, the yield rate of water-insoluble dietary fiber was 80.89%, holding water capacity was 8.58 g/g and swelling property was 8.73 ml/g.
