Description
Technical field
The present invention relates to food processing technology fields, and the preparation method of tailored flour is baked more particularly to a kind of sweet potato waste.
Background technique
Sweet potato is also known as sweet potato, red tongue fur, sweet potato, pachyrhizus.The nutritive value of sweet potato is very high, is a kind of health food of dietotherapeutic
Product.Sweet potato is the food of low fat, low calorie, can effectively prevent carbohydrate in human body and is changed into fat, has weight-reducing to protect young man
The effect of strong, to effect that the elderly has bowl spares and blood, nourishing generate fluid, wide stomach, defaecation secret, scientists think that it has drop
Sugar, lipid-loweringing, replenish the calcium, anti-aging and improve immunity the effects of.
Sweet potato is at present mainly for the production of starch and starch product.A large amount of sweet potato waste is generated in starch production process,
It is mainly used for Feed Manufacturing and manufacture biogas, and the overwhelming majority is abandoned as waste residue, has ignored considerable sweet potato dietary fiber, from
In sweet potato waste extract dietary fiber product is made, it can be achieved that resource effective use, reduce environmental pollution.Existing sweet potato waste meals
The preparation for eating fiber is mostly to fall the substances such as starch, protein and fat therein with enzymatic hydrolysis, and it is fine to obtain single diet
Tie up product, such as using the material residue of sweet potato production starch as raw material, it is cleaned, remove sand, hydrolyze, it is prepared by homogeneous, dehydration, the techniques such as drying
It forms.Gelatinization hydrolysis process: it the additive amount 1.0% of alpha-amylase, solid-liquid ratio 1:15, pH6.5, keeps the temperature under the conditions of 75 DEG C
120min；Then it cools down；It adjusts pH to 4.5, keep the temperature 60min under the conditions of 0.8%, 60 DEG C of additive amount of carbohydrase；Heated-air drying
Technique: material thickness 6mm, drying temperature are 65 DEG C；Dry wind speed is 1.0m/s.There are following technical problems for existing method: (1)
Production and processing is complicated, at high cost, and loss is big and secondary pollution is serious；(2) starch and sugar are lost big, influence the mouth of converted products
Sense.
Summary of the invention
In view of the above technical problems, the purpose of the present invention is to provide the preparation method that a kind of sweet potato waste bakes tailored flour,
With produce potato it is aromatic it is strongly fragrant, rich in dietary fiber, processing raw material for bakery product can be added to.
The technical solution adopted by the present invention is that:
A kind of sweet potato waste bakes the preparation method of tailored flour, comprising the following steps:
(1) feedstock processing: richness amyloid taro kind of the selected Yangze river and Huai river one with plantation rejects mildew, damages by worms and seriously
The potato wedge of defect cleans de- epidermis；
(2) impregnate: the pH value with 1wt%NaOH solution adjustment immersion water is 10-11, soaking time about 10-12h, water
Temperature control at 35-40 DEG C；
(3) it is crushed: the sweet potato after immersion being sent into hammer crusher and breaks into fragment, the size of fragment is 2 centimeter squares
Below；
(4) grind filtering: sweet potato fragment in step (3) be sent into Buddha's warrior attendant is sanded plus water mill is at slurry, sweet potato weight with plus
The ratio of water is 1:3-3.5；It is ground using twice, the technique of shunting sieving, 40 mesh of slubbing sieve pore, 60 mesh of secondary screen hole；Add
Water is very few, then phosphoric acid is big, easily causes filter net jam, influences filter effect, and amount of water is excessive, will cause free state starch
It is lost with sugar, while waste and sewage load being caused to increase；
(5) starch processed, separation potato slag: starch slurry after filtering in step (4) is passed through into sieve pore into stock tank is deposited with water, is entered
Starch production process；Isolated potato slag is collected spare；
(6) boiling of potato slag, cooling: potato slag described in step (5) being placed in continuous digester and carries out boiling, and digester is adopted
With 121 DEG C of steam, digestion time 10-15min；Then the potato slag after boiling Air cooler is sent into be cooled to room temperature；When boiling
Between it is short, then starch cannot cure completely, and fiber softening is poor, and digestion time is long, then starch and residual sugar are oxidizable, influence flavor and mouth
Sense；
(7) anxious to freeze: potato slag after cooling in step (6) being placed in mono-frozen machine and suddenly freezes 5-7min under -35 DEG C of environment；It is anxious
Freezing the time is determined according to material tissue characteristics and quality size, is passed through with speed as early as possible by the maximum ice crystal band temperature of quick-frozen material
Point is spent, the tissue morphology and mouthfeel quality for keeping material cell, excessive velocities are maximized, then the central temperature for being frozen food reaches
Less than cryohydric point temperature, it will cause frosting, food material histocyte dehydration, influence food quality morphology and mouthfeel, speed mistake
Slowly (it is relatively low to generally refer to refrigerator power, minimum temperature and cooling capacity compensation do not reach requirement), food material cannot be when effective
It is interior equally to cause food material form and mouthfeel quality poor by maximum ice crystal band, while meeting waste of energy, it reduces and produces effect
Rate；
(8) it thaws, dry: the potato slag after suddenly freezing in step (7) being subjected to normal temperature unfreezing or uses microwave thawing；Then it adopts
With continuous tunnel formula dryer, 105 DEG C of heated-air dryings, until potato slag water content≤11%；
(9) it refines: after cooling, fine grinding to 80 mesh, packaging.
Sweet potato waste of the present invention bakes the preparation method of tailored flour, wherein twice described in step (4) are ground, head
Road is 3-3.5 Baume degrees, and two be 2-2.5 Baume degrees.
Sweet potato waste of the present invention bakes the preparation method of tailored flour, wherein the revolving speed of crusher described in step (3)
For 1480r/min.
Sweet potato waste of the present invention bakes the preparation method of tailored flour, wherein mono-frozen machine described in step (6) is using company
Continuous tunnel type single-freezing machine.
The invention has the advantages that:
Sweet potato waste of the present invention bakes the preparation method of tailored flour, based on anxious jelly production technology, auxiliary boiling,
The techniques such as fine grinding and drying solve the softening of destarched sweet potato meal cellulose and the aging of residual starch, can effectively keep residual sugar,
Enhance ingredient flavor；The product obtained using the preparation method has strong sweet potato fragrance, crisp and fragrant is palatable in canescence；Add
It is added in bakery product, can be constituted with condensed food nutrition, there is certain healthcare function, while effectively replacing during the preparation process
For complicated cumbersome enzymolysis process, production cost is reduced, waste and pollution are reduced.
Sweet potato waste of the present invention bakes the preparation method of tailored flour, and mono-frozen machine described in step (6) uses continuous tunnel
Road formula mono-frozen machine, it is high that quick, operation is easy, temperature uniformly, suddenly freezes uniform quality, productivity.
Below in conjunction with specific embodiment, the invention will be further described.
