Description
Technical field
The present invention relates to starch method for producing, belong to food processing field, specifically a kind of wheaten starch system
Preparation Method.
Background technology
Wheat is cultivated area most wide cereal in the world, and the people in the whole world 1/3 is using wheat as staple food.In China, wheat
It is mainly used for making food and producing starch.Due to containing special glutelin meal component in wheat flour, process wheaten starch
Commercial value greatly promote, the production of wheaten starch and Gluten is increasingly paid attention to by Starch Production industry, wheaten starch
Shared ratio is continuously increased in world's starch total output, and wheaten starch is by amylose (content is 23%~25%) and branch
Chain starch (content 75%~77%) is constituted.Wheaten starch gelatinization performance is good, and viscosity is low, so being widely used in medicine, food
Deng industry, particularly hidden for high fruit glucose syrup, sweet tea in the food industry such as agent, meat product, instant food, baking industry.It is small
The form of wheat Gluten is in powdered, and color and luster is in faint yellow, and slightly sweet taste is a kind of nutritious natural plant protein source,
Its Main Ingredients and Appearance is made up of alcohol soluble protein and glutenin, with the stronger elasticity of good extensibility.Due to these characteristics, paddy
Protein powder is in terms of food, chemistry, medical industry, the bread baking particularly in food industry, the edible film of instant food
And casing, all too busy to get away Gluten of all kinds of imitative meat type food developments.Gluten is water insoluble, and glutelin particle is partly suspended in after water suction
In water, binding agent and nutrition fortifier as premixed feed trace element and vitamin can improve the nutriture value of feed
Value.
Because wheat flour composition is complex, the Multiple components such as starch therein, fat, protein, pentosan are tangled
Together, a kind of network-like structure is formed.Therefore, during Wheat Production starch, each composition is interfered, and causes wheat to form sediment
Powder and Gluten separative efficiency be not high, and purity is low, and traditional production technology seriously restricts wheat starch quality, directly results in follow-up
The problems such as viscosity of sludge is high in production process, color is deep, technology difficulty is big.
At present, wheaten starch industrialized production is mainly using Martin's method washing production technology and three-phase decanter process.Three-phase
Decanter process is the most batter method processing technologys of domestic introduction.Compared with traditional Martin's method, three-phase decanter process water consumption
Small, mechanical automation degree is high, starch yield is big, friendly environment, is the development trend of wheat starch production.But from product matter
Do not improved significantly in terms of amount, yield and water consumption control.According to statistics, 1t wheaten starches are often produced, water consumption about 30t is needed,
Wherein high concentrated organic wastewater (albumen containing dissolubility, pentosan etc.) discharge capacity is between 5~12t.If directly discharging, not only waste
Resource, and serious environmental pollution can be caused.
It is domestic at present that there are reports is carried out by way of adding enzyme preparation in starch and Gluten process
Processing.A kind of complex enzyme of Application No. 201010221731.0 invention, is added by hemicellulose during wheat starch production
Plain enzyme, glutamine transaminage, the complex enzyme of phytase composition, but the addition of this complex enzyme improves Gluten yield and pure
Degree, but do not account for the improvement of wheaten starch yield and quality.Wheaten starch yield is relatively low in products obtained therefrom, and non-starch material
Content is higher, it is impossible to be effectively improved follow-up sugar refining technology.The patent of application number 201110118428.2 is formed sediment there is provided a kind of wheat
Powder complex enzyme, but Martin's method production wheaten starch is only limited to, there can not be effect in currently advanced three-phase decanter production technology
With.
Therefore, how a kind of effective method is developed during three-phase decanter process production wheaten starch, carried
High A starch, glutelin powder purity and yield, while the content of material such as albumen, fat in reduction A, B starch to greatest extent, improves it
Availability, reduces subsequent technique difficulty, will have important practical significance and economic value.
The content of the invention
Technical problem：It is an object of the invention to overcome the weak point of above-mentioned existing background technology, and provide a kind of small
Wheat starch preparation method, improves A starch, glutelin powder purity and yield, while albumen, fat in reduction A, B starch to greatest extent
Deng content of material, the discharge of pollutant in wheaten starch preparation process is solved, the difficulty of subsequent filter technique is significantly reduced,
Reduce environmental pollution.
Technical scheme：To achieve the above object, the present invention provides following technical scheme：
A kind of wheaten starch preparation method that the present invention is provided, it comprises the following steps：Using wheat flour as raw material, wheat

Preferably, the pH value is 6.
Preferably, described wheat flour using high starch yield, high gluten content, low ash content, low damage rate close to
The flour of special second clear flour is used as raw material.
Beneficial effect：Compared with prior art, the beneficial effect of invention is：
(1), by the synergy between enzyme system, production has effectively been decomposed using complex enzyme formulation is added in present invention process
During protein and pentosan, high adhesive material in flour of degrading, improve starch and while Protein Separation effect, release
Put fatty present in flour, discharged in three-phase decanter separation process with light phase, it is to avoid starch-fat is formed in liquefaction process
Fat compound and the harmful effect brought；The discharge of pollutant in wheaten starch preparation process is solved, is significantly reduced follow-up
The difficulty of filtering technique, reduces environmental pollution, improves starch rate, and product quality is significantly improved, and cost is greatly reduced.
(2) the inventive method is due to adding complex enzyme formulation, by the synergy between enzyme system, is effectively increased starch receipts
Rate, improves purity of starch, effectively increases raw material availability, greatly reduce production cost；Meanwhile, reduce material viscosity
And water consume, reduce subsequent technique difficulty so that wheaten starch is not required to any special process processing.
