Abstract
The present invention provides a kind of intelligent dried starch homogeneously to take off branch polymerization.Using starch as raw material, homemade intelligent dry method starch is added based on deal homogeneously to take off in branch polymerization machine, vacuumize and heat in closed rotation process, the spray non-volatile organic acids of uniform atomizing at the same time, temperature is adjusted according to X-ray and differential scanning result, after starch debranching and polymerization effect reach ideal indicator, automatic slowly cools down 80 DEG C.Realize the intelligent combination of the processes such as the chain rupture of starch, de- branch, polymerization, monitoring.Compared with chemical modification under the conditions of conventional liquid, technological process is simplified, eliminates substantial amounts of chemical reagent, while any waste water will not be produced, is had laid a good foundation for the preparation of resistant starch.
Description
Technical field
The invention belongs to food machinery biological technical field, and in particular to a kind of intelligence dried starch homogeneously takes off Zhi Juhe side
Method.
Background technology
Starch is a kind of polycrystalline high polymer, and a part of molecules align is into loose amorphous area, another part point in its particle
Crystal region that is sub then being arranged in high-sequential, crystalline texture are mainly connected by starch molecule by hydrogen bond, and crystal region accounts for
The 25%~50% of grain.This design feature of starch molecule, limits the use scope of starch, such as starch crystals area molecules align
Closely, water and chemical reagent etc. are not easy to touch the molecule in crystal region, cause the gelatinization point height of starch, chemical reactivity low
The big and numerous hydroxyl of relative molecular weight Deng starch causes viscosity each other with hydrogen bond association into close network structure
Excessive, poor fluidity.Therefore, how research changes starch granules structure, crystal region supramolecular structure and reduces starch crystals
The method in area is to improve the physicochemical properties of starch, the reactivity of raising starch becomes an extremely important research class
Topic.
Resistant starch is also known as resistant starch, impedance starch and indigestibility starch etc., refers in the small intestine of Healthy People
The starch of absorption and its general name of decomposition product cannot be digested.From physiologically saying, RS has the physiological function similar to dietary fiber,
It if do not degraded by human small intestine's enzyme, can be utilized, and have the advantages that in contrast more by large intestine microorganism：（1）Resistance is formed sediment
Powder can resist the decomposition of enzyme, and release glucose is slow in vivo, has relatively low insulin response, can control blood glucose balance,
Reduce hunger, particularly suitable patients with diabetes mellitus；（2）Resistant starch has the function of soluble edible fibre, can after food
Increase Fecal wastes, reduce constipation, reduce the danger of colon cancer；（3）Resistant starch can reduce the amount of cholesterolemia and triglyceride,
Because of the amount of cholesterol and triglyceride increase in excreta after edible resistant starch, thus there is certain antiobesity action.Eating
In product processing, the functional character of resistant starch uniqueness can be utilized, produces high-quality food.Resistant starch is suitable for based on cereal
The food formula of raw material is wanted, can be used to improve food processing technology, increases the brittleness of food, dilatancy and improves final products
Quality.In addition, its color is white, it is added to the appearance that food is not interfered with food and will not be influenced as dietary fiber
The mouthfeel of food.Resistant starch is easily ground into tiny particle, and feeling of grittiness will not be produced by being added in food, beverage.Foreign countries are
Apply it in the flour products such as bread, steamed stuffed bun, snack, macaroni, biscuit.Wherein most strikingly RS is in bread
Application, RS can be added in bread instead of dietary fiber, solve dietary fiber influence bread rise, poor taste the shortcomings of.
Some researches show that after adding RS, the puffed degree increase of food, density declines, and brittleness is improved.By the puffing food added with RS
Product are dipped into the beverages such as milk in use, though its quality softens but not collapsed because of water suction, and can maintain the long period
Brittleness.Current development trend is seen, world population, still in reduced levels, does not reach much also in the consumption of dietary fiber
Needed by human body requirement.It is daily 20-35g in the consumption per head that American diet fiber association is recommended, but is actually only 12-
17g, almost differs half.Even in the preferable New Zealand of situation, its consumption figure is also not reaching to the upper limit of standard requirement.Hair
Up to country even in this way, the consumption per head of developing country is even more much insufficient.It can be seen from the above that resistant starch is a kind of great
Physiological function potentiality, the component that can be used for manufacture high-quality food with good food processing feature, have extensive market
Prospect and development potentiality.The present invention homogeneously takes off branch polymerization machine using homemade intelligent dry method starch and carries out mechanical activation to starch,
Compared with chemical modification under the conditions of conventional liquid, technological process is simplified, eliminates substantial amounts of chemical reagent, while will not produce
Any waste water, haves laid a good foundation for the preparation of resistant starch.
The content of the invention
It is an object of the invention to provide a kind of intelligent dried starch homogeneously to take off branch polymerization, with changing under the conditions of conventional liquid
Learn modification to compare, simplify technological process, eliminate substantial amounts of chemical reagent, while any waste water will not be produced, form sediment for resistance
The preparation of powder is had laid a good foundation.
A kind of mechanochemistry method that wheaten starch is modified, it is characterised in that comprise the following steps：
Step 1, by weight, 8~10 parts of Raw Wheat Starch add homemade intelligent dry method starch homogeneously de- branch polymerization machine
In；
Step 2, intelligent dry method starch homogeneously takes off branch polymerization machine and is vacuumized during rotation, and uniform atomizing spray is non-waves
Hair property organic acid；
Step 3, intelligent adjustment temperature and organic acid additive amount.Using in X-ray and differential scanning monitoring device starch it is de-
Branch and extent of polymerization, and corresponding temperature and acid adding amount is automatically generated according to data above so that temperature and acid adding amount are realized and moved
State changes, and lays the foundation for the preparation of resistant starch.
Further, it is that first homogeneously takes off branch both at home and abroad that homemade intelligence dry method starch, which homogeneously takes off branch polymerization machine, in step 1
The technique such as polymerization machine, equipment collects atomization spray acid, homogeneous, high temperature takes off, a polymerization is in quaternity, according to X-ray and differential scanning
The dynamic change for realizing temperature and acid adding amount, simplify technological process.
