Description
Technical field
The present invention relates to food processing technology field, more particularly to a kind of method of efficient utilization sweet potato dregs.
Background technology
Sweet potato is one of cereal crops of China, and its cultivated area and yield occupy first place in the world, and sweet potato dregs are that sweet potato is formed sediment
Accessory substance produced by powder extraction process, accounts for 10%～14%, and which is fallen by many enterprises with discharge of wastewater, and wherein containing big
The nutriment of amount, including starch, dietary fiber, protein etc., wherein content of starch highest accounts for 48.26%, and dietary fiber accounts for 2
6.73%, protein accounts for 3.35%.Sweet potato dregs are carried out into deep processing and comprehensive utilization not only can reduce environmental pollution, can be with
Increase its economic worth, realize the sustainable use of resource.
Dietary fiber is the nutrient that a class is difficult digested absorption, mainly including cellulose, hemicellulose, resin, fruit
Glue and lignin etc..Food science research shows:Dietary fiber digested can not be absorbed in human small intestine, in big enteral
Can by microbial portion or all of.Dietary fiber has important function to the digestive system health of human body, can control
The blood sugar of human body, blood lipid level, prevention of cardiovascular disease, cancer, diabetes and Other diseases.It is insoluble in dietary fiber
The Main Function of composition is to make enteron aisle produce mechanical creeping, and soluble component more plays metabolic function, such as affects sugar
Class and lipid metabolism etc..Therefore in dietary fiber, the proportion of composing of soluble component is the important of impact physiological function of diet fiber
Factor.The balanced diet fiber composition requirement Soluble Fiber of expert advice accounts for more than the 10% of total dietary fiber, and natural
In fiber, the content of Soluble Fiber is far below this numerical value.
Sweet potato dregs are using as follows：1st, fresh sweet potatoes slag culturing directly animal, using sweet potato waste produce protein feed；2nd, sweet potato waste
Can be added in numerous food, for example bread, noodles, jelly, biscuit and beverage etc..3rd, cultivating in edible fungus culturing
Material；4th, the extraction of active ingredient：Extract pectin, crude protein, dietary fiber, polyphenols etc.；5th, commercial Application production ethanol,
Hydrogen, compound sugar, organic acid, lipopeptide antibiotic and antistaling agent etc..
Used as the accessory substance of sweet potato starch industry, fresh sweet potatoes slag water content is high, and a large amount of storages are easily gone mouldy, in transportation
Cost is again too high, is the bottleneck of the further deep processing and utilization of sweet potato waste.The process of sweet potato dregs is never obtained with transition problem
Solve well.Extract such as from sweet potato dregs dietary fiber, pectin technology it is increasingly mature, but it is simple fine by meals are extracted
Dimension and pectin can not Transformation of sweet potato slags in a large number；Other methods are also or to there is energy consumption big, or utilization rate is not high, or using effect
Benefit is low, or environment it is unfriendly etc. the problems such as.
The content of the invention
For solving above-mentioned the deficiencies in the prior art, the present invention provides a kind of method of efficient utilization sweet potato dregs.The present invention is carried
For a kind of efficient utilization sweet potato dregs method, by soybean dietary fiber technology and combine microwave radiation technology, double enzyme resolving tech
Reason sweet potato dregs, reapply in uncooked wet noodle, make uncooked wet noodle nutritious, especially containing high dietary-fiber and high meals are fine
Soluble dietary fiber in dimension and insoluble diedairy fiber composition are scientific and reasonable.This technology saves energy consumption, and utilization rate is high, environment
Close friend, Product Safety are high.
In order to realize foregoing invention purpose, embodiment of the present invention is：A kind of method of efficient utilization sweet potato dregs, including
Following steps：
（1）By fresh sweet potato slag, clean, soybean dietary fiber uses 200 mesh screens, leave lower part of screen point, obtain sweet potato dregs liquid,
Its moisture is 50%～60%；

2h.By microwave treatment, sterilization can be carried out, also help is provided for postorder enzymolysis, improve hydrolysis result；
（3）Sweet potato dregs liquid after microwave treatment is adjusted into its pH3～4, adds mixed enzyme, maintain temperature 400C～500C, enzyme
2～3 h of solution, the mixed enzyme are the mixture of pectase and cellulase；
（4）Moisture is added water in the sweet potato dregs liquid after enzymolysis 60%～70%, adjusts temperature to 250C～350C, adds
Salt and sodium carbonate, fully dissolve；
（5）Step is added in flour（4）Prepared enzymolysis sweet potato dregs liquid, Jing and face, once curing, roller sheet, post cure,
Calendering, slitting, packaging, that is, be obtained sweet potato dregs uncooked wet noodle.
As optimization, step（3）In, in the mixed enzyme, the weight proportion of pectase and cellulase is 1：1, pectase
It is 5000～10000IU/g respectively with cellulase activity.Sweet potato filter residue with weight proportion of the enzyme dosage with sweet potato filter residue is mixed is
1：0.1%～0. 3%；
As optimization, step（4）In, the sweet potato dregs liquid, salt, sodium carbonate weight proportion be 30～40 parts of sweet potato dregs liquid,
0.5～1. 0 parts of salt, 0.05～0.2 part of sodium carbonate.
As optimization, step（5）In, the weight proportion of the flour and enzymolysis sweet potato dregs liquid is 100:30～40.
Advantages of the present invention：Without drying process, energy consumption is saved；Digested using the auxiliary pectase of microwave and cellulase
Sweet potato dregs, product contain high dietary-fiber and the soluble dietary fiber in high dietary-fiber and insoluble diedairy fiber composition section
Learn reasonable.Sweet potato dregs utilization rate is high, and substantially no waste is produced and environmental friendliness, and Product Safety is high.And present invention production
