In China, sweet potato is mainly used for extracting starch, making bean vermicelli, vermicelli and exploitation sweet potato beverage etc., produces a large amount of potato slags in process, accounts for 10%~14% of raw material, and wherein dietary fiber content is up to 25% left and right.These potato slags are most of is at present used for feed or directly abandons, and according to statistics, approximately has every year 5000 ten thousand tons of sweet potato dregs be used as refuse and abandon.Fresh potato slag water content, up to 80%, is difficult for storing, transporting, and putrid and deteriorated rear generation stench, causes serious environmental pollution.The a large amount of dietary fibers that contain in sweet potato dregs are extracted, both can obtain the dietary fiber of high physiologically active, improve the added value of sweet potato processing, increase farmers' income, also can reduce environmental pollution simultaneously.The exploitation of sweet potato waste residue, for deep processing and the comprehensive utilization of sweet potato provides a new way.
At present, extract dietary fiber both at home and abroad and take chemical method as main, this technique is simple, input cost is low, but in process, the physicochemical property of diet fiber product and physiological function are had a significant effect, as hot alkali dipping with repeatedly both reduced the productive rate of dietary fiber with water rinse, make again the retention ability of product and expansive force obviously decline; Inevitably discharge large amount of sewage simultaneously, to environment cause serious pollution and disposal cost high; Adopt in addition enzymatic isolation method, membrane separation process to obtain the higher dietary fiber of purity, but cost is higher and wayward in large-scale production.
Summary of the invention
The present invention be take and addressed the above problem as object, and a kind of method of preparing dietary fiber in sweet potato dregs is provided.The advantages such as the method is the method with molecular sieve-microorganism fermentation combination, and that this process has is easy and simple to handle, reaction condition is comparatively gentle, pollution-free.
