Description
Technical field
The present invention relates to a kind of method that fashion of extrusion prepares high dietary fiber content resistant starch, belong to food ingredient skill
Art field.
Background technology
Resistant starch (resistant starch) is also known as enzyme resistant starch and indigestibility starch, it 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 some natural
In food, such as potato, banana, rice all contain resistant starch, and particularly the cornstarch of high amylose starches forms sediment containing resistance
Powder is up to 60%.For this starch compared with other starch difficult degradations, digestion is slow in vivo, absorbs and all slower into blood.Its
Property has certain slimming effect, starts to be favored be subject to 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, keep colon health and intestines to glue
The integrality of film.Resistant starch is also used as a kind of medicine.It has with many middle colonic diseases contacts, including can reduce
The incidence of cancer.In addition, resistant starch can also reduce the generation of cascade of metabolic syndrome, including insulin resistance, it is high
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.Count, mainly include 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 things, are free from side effects human body.Lasting food
Adjusting and movement can make fatty liver recover normal.Do not take medicine, do 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.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of fashion of extrusion prepares high dietary fiber content resistant starch
Method.
Technical solution of the present invention is as follows：
A kind of method that fashion of extrusion prepares high dietary fiber content resistant starch, includes the following steps：
(1) starch milk is modulated, adjusts pH value 50~80 DEG C to be heated to, by starch on dry basis 0.02%~0.2% to 4.0~6.0
(percentage by weight) adds Pullulanase, reacts 0.5~2h, and enzyme deactivation is lived, and reaction solution is made；
(2) resistant dextrin of starch on dry basis 20~40% (percentage by weight) is added into reaction solution made from step (1),
Fully mix, the hybrid solid for being 10~30% through dry obtained moisture；
(3) the obtained mixing solid of step (2) is added in screw extruder and carries out extrusion process；Extruding condition be into
60~80 DEG C of material temperature degree, extrusion temperature are 100~300 DEG C；
(4) add water to modulate the solid powder that step (3) extrusion process obtains, be then heated to 60~80 DEG C, add dry
The ratio addition alpha-amylase of base 0.001~0.01% (percentage by weight), handles 0.5~4h, enzyme deactivation, is made resistant starch
Slurry；
(5) by resistant starch slurry centrifuging and taking precipitation made from step (4), resistant starch is made.
Preferable according to the present invention, in the step (1), starch is cornstarch, wheaten starch, rice starch, cassava
Starch, potato starch and/or sweet potato starch.
It is further preferred that in the step (1), starch is amylomaize.
It is preferable according to the present invention, in the step (1), the mass concentration 10%~30% of starch milk.
It is preferable according to the present invention, in the step (2), the addition of resistant dextrin is 20%, 25%, 30%, 35%,
40%.
Preferable according to the present invention, in the step (3), screw extruder revolves extruder for single screw rod or twin-screw rotation is squeezed
Press.
Preferable according to the present invention, in the step (4), it is 10%~30% to add water modulation quality concentration.
Preferable according to the present invention, in the step (4), enzyme deactivation lives condition as 120~150 DEG C, keeps the temperature 2~5min；
It is preferable according to the present invention, in the step (5), centrifuge under the conditions of 1000~1500r/min centrifugation 5~
