Description
Technical field
The invention belongs to dietary fiber preparing technical field, and in particular to a kind of preparation method of wheat-bran dietary fiber and wheat
Bran dietary fiber.
Background technology
Dietary fiber is a kind of important non-nutritive element, and it is a kind of SNSP and oligosaccharides in carbohydrate etc.
Indigestion part, it can neither be digested and assimilated by human gastrointestinal tract, can not produce energy.But in recent years, more and more
Research shows that the intake of dietary fiber is closely related with health, and constipation, obesity, glycosuria can be reduced by taking in enough dietary fibers
The danger that disease, angiocardiopathy and intestinal tract occur.For example, dietary fiber largely can absorb moisture in enteron aisle, make excrement
Soft condition is kept, effectively activates the beneficial bacteria in enteron aisle, promotes beneficial bacteria amount reproduction, creates enteron aisle environmental health, especially
Apply to improve prolonged constipation；Meanwhile the dietary fiber content improved in meals can reduce the heat energy of intake, in enteron aisle
Digesting and assimilating for interior nutrition also declines, and can also extend food residence time in the intestine, reduce the infiltration rate of glucose, not only
The effect of with fat-reducing, and diabetic symptom can be improved.
Dietary fiber can be divided into soluble dietary fiber and non-soluble dietary fiber according to whether being dissolved in water.Many plants
Most dietary fibers are non-soluble dietary fiber in raw material and its byproduct.For example, wheat bran is that wheat is outermost
Epidermis, after wheat is machined by flour milling, become flour and wheat bran two parts, wheat bran is exactly the crust of wheat, and majority is as feed
Use, but because wheat bran wherein contains higher fibre composition, therefore used also as preparing dietary fiber.In the food industry
It is to be modified non-soluble dietary fiber to change into soluble dietary fiber to prepare most of soluble dietary fiber.Traditional place
Reason method such as enzymatic isolation method, chemical method, this quasi-tradition method production wheat bran soluble dietary fiber exist mostly purity it is low, production
The problems such as measuring low, poor taste, some even can also cause the reduction of product moisture holding capacity, influence dietary fiber effect.Therefore, research and development
A kind of preparation method for the wheat-bran dietary fiber that can solve the problem that above mentioned problem is very important.
The content of the invention
The first object of the present invention is to provide a kind of preparation method of wheat-bran dietary fiber.
The second object of the present invention is to provide what a kind of preparation method by described wheat-bran dietary fiber was prepared
Wheat-bran dietary fiber.
The first object of the present invention, which is achieved in that, specifically includes following steps：
A, pre-treatment：Add distilled water after 110~120 DEG C of 30~40min of boiling through concentrating, doing after drying, crushing in wheat bran
Dry, crushing, then raw material is adjusted feed moisture content to 100~150%, Ran Houting using slowly sprinkling adds water while stirring
Only stir and take out raw material, seal 5~30min, then raw material is fitted into steam explosion device, 0.8 is risen in 1~4min~
Moment release after 1.0Mpa, 50~80s of pressurize, take out raw material and add the NaOH solution that mass percent concentration is 2.5~3,
25~30min is extracted under 160~200W power and obtains extract solution, then after extract solution is centrifuged into 3~4min with 5500~6000r/min
Filtering, takes filter residue, and the mass ratio 1 of water, filter residue and water is then added in filter residue:1~6, add removing impurities enzyme and digest 1~3.5h,
The mass ratio of filter residue and removing impurities enzyme is 1:0.025~0.035, hydrolysis temperature is 25~55 DEG C, and pH value is 5.0~8.0, after filtering
It is dietary fibre materials to take filter residue；
B, prepared by semi-finished product：The obtained dietary fibre materials of step A are added into water, the mass ratio of dietary fibre materials and water is 1:3
~5, add 1~4h of enzymatic hydrolysis, the mass ratio of dietary fibre materials and hydrolase is 1:0.02~0.03, hydrolysis temperature
For 30~50 DEG C, pH value is 4.0~6.0, and it is semi-finished product that filtrate is taken after filtering；
C, purify：To the semi-finished product heat inactivation in step B, filtrate is taken after filtering, concentrating filter liquor obtains concentrate, then dense
Add absolute ethyl alcohol in contracting liquid, the mass ratio of concentrate and absolute ethyl alcohol is 1:2~5, after mixing stand 1.5~2h, then with
4000~4500r/min centrifuges taking precipitate after 8~15min；
D, post-process：By obtained sediment in step C through homogeneous, be drying to obtain manufactured goods.
The second object of the present invention is achieved in that what is be prepared by the preparation method of described wheat-bran dietary fiber
Wheat-bran dietary fiber；This wheat-bran dietary fiber has that purity is high, palatability is excellent, fiber diameter is small, moisture holding capacity and swelliong power
The advantages of strong.
Beneficial effects of the present invention：The method of the present invention uses in preceding processing and carries out thermophilic digestion processing, vapour to raw material
Quick-fried processing, the mode being combined is ultrasonically treated, can effectively destroy raw material mix tissue, its inclusion is fully exposed, and tie
Removing impurities processing is closed, further reduces non-dietary fiber component in raw material, the raw material after pre-treatment not only contributes to reinforcing fiber
The hydrolysis result of the complex enzyme of plain enzyme or cellulase and hemicellulase, make enzymolysis more fully so as to improve manufactured goods solubility
The purity of dietary fiber, and the palatability of manufactured goods can be effectively improved；Purified, further improved pure again after enzymolysis
Degree, manufactured goods soluble dietary fiber have the advantages of purity is high, the preparation of the high-quality that is particularly suitable for use in soluble dietary fiber；
The method manufactured goods wheat bran soluble dietary fiber of the present invention also has that fiber diameter is small, moisture holding capacity and swelliong power are strong
Advantage；The method of the present invention is by the use of wheat bran as raw material, the problem of can reducing the wasting of resources and environmental pollution.
