Description
Technical field
The present invention relates to a kind of preparation methods of resistant starch, belong to food ingredient technical field.
Background technology
Resistant starch (resistant starch) is also known as enzyme resistant starch and indigestibility starch, cannot be by small intestine
Enzymolysis, but can play fermentation reaction with volatile fatty acid in the intestines and stomach colon of people.Resistant starch is present in certain natural
In food, such as potato, banana, rice all contain the cornstarch of resistant starch, particularly high amylose starches containing resistance shallow lake
Powder is up to 60%.This starch is difficult to degrade compared with other starch, and digestion is slow in vivo, absorbs and enters blood all relatively slowly.Its
Property has certain slimming effect, starts to be favored by people seeking beauty in recent years similar to disappearing fibre.Resistant starch can
The decomposition of enzyme is resisted, release glucose is slow in vivo, has relatively low insulin response, can control blood glucose balance, reduces hungry
Starve sense, particularly suitable patients with diabetes mellitus.
Resistant starch can be applied in food, including medical food and dietary supplements, colon health and intestines be kept to glue
The integrality of film.Resistant starch is also used as a kind of drug.It has with many middle colonic diseases contacts, including that can reduce
The incidence of cancer.In addition, resistant starch can also reduce the generation of cascade of metabolic syndrome, it is high including insulin resistance
Blood glucose, blood insulin is excessive, dyslipidemia, and blood Fibrinolysis is abnormal, diabetes, hypertension and angiocardiopathy.Resistance
Starch can be also used for obesity controlling.
As Chinese patent literature CN104938904A (application number 201410139000.X) discloses a kind of fatty liver person's food
Staple food flour.It counts, mainly includes in mass ratio：The special powder of 60 parts~70 portions wheats, 8 parts~9 parts soyabean protein powders, 10 parts
~11 analysis for soybean powder, 4 parts~5 parts gluten powders, 4 parts~5 parts resistant starches, 3 parts~4 parts konjaku powders, 3 parts~5 parts resistances
Dextrin.Convenient based on wheat flour, supplemented by grain other compositions, after fatty liver person's feed, blood fat does not increase, mouthfeel
It is good, fat content in sweet wine can be made to reduce and reduce the effect of blood fat.Product have high protein, high dietary-fiber, compared with homovitamin,
The characteristic of low-carb is made of natural raw grain, and additive-free and Drug objects are free from side effects to human body.Lasting food
Adjusting and movement can make fatty liver restore normal.It does not take medicine, does not have an injection, price does not improve, essentially identical with long patent flour.Without fat
Fat liver person also can be used as defence sex-health products to eat, and can be fabricated to and steam Mo, noodles, dumpling, steamed twisted roll, oil tea etc..
To improve the content of its dietary fiber, the method for conventionally manufactured resistant starch is often taken makes its paste by heating starch
Change and cool down rapidly, make dextrin aging, since time processing is often extremely difficult to dietary fiber content requirement, often to repeat
Processing can be only achieved requirement several times, and production technology is excessively complicated, while dietary fiber content is still difficult to reach high-end product
In application requirement.
