Research Status and Progress on Efficient Utilization of Sweet Potato Residue
Sweet potato residue,as the main by-product of sweet potato starch processing,mainly consists of residual starch,dietary fiber,etc.With the cluster development of sweet potato starch processing industry,the problem of efficient and com-prehensive utilization of potato residue has become a problem for the sustainable development of the industry.The existing treatment methods can't make efficient use of sweet potato residue,which causes waste of resources,but also seriously pol-lutes the environment.The paper summarized the composition and components of sweet potato residue,and focused on the re-search and application of sweet potato residue in animal feed,dietary fiber,pectin,edible fungus culture medium,fuel ethanol and other aspects.For the pretreatment capacity of sweet potato dregs,study and application of functional components extraction and special medical food,research and development of special equipment for efficient treatment of sweet potato residue and the development of high value-added and sophisticated,the problems in four aspects were discussed and put for-ward scientific and feasible suggestions.Finally,how to make better use of sweet potato residue was prospected and summa-rized,in order to provide necessary theoretical basis for efficient and comprehensive utilization of sweet potato residue.
