Description
Technical field
The invention belongs to technical field of food biotechnology, is related to a kind of oat bran intensive processing technology, specifically with oat
Wheat bran is raw material, utilizes the skill of biological enzyme Joint Production avenabeta glucosan nutrient powder, dietary fiber micro powder and avenin
Art.
Background technology
Oat has higher nutritive value, compared with other cereal, in protein, dimension life as a kind of rain fed crops
The nutrient index contents such as element, mineral element and dietary fiber are high, and nutrition equilibrium modern studies show, protein content in oat
It is abundant, occupy the first in cereal, and the essential amino acid Compositional balance in avenin, its amino acid pattern is close to FAO/
The provisional pattern of amino acids that WHO is promulgated is in addition, be rich in soluble dietary fiber beta glucan and insoluble meals in oat bran
Fiber.Its chemical name of beta glucan is（1-3）（1-4）- callose, it is a kind of non-starch linear polysaccharide, it is raw at present
The general physiological action for thinking beta glucan of thing medical field and nutrition educational circles mainly have gut purge effect, reconcile blood glucose, reduce cholesterol,
Improve immunity.And insoluble dietary fiber plays important life to fat-reducing, diabetes mellitus prevention, promotion function of intestinal canal improvement etc.
Manage adjustment effect.
In existing patented technology, existing some reports on extracting beta glucan from oat, such as patent
200710018232 provide a kind of method for separating glucan from cereal bran using membrane separation technique, and this method utilizes egg
White matter solubility in alkalescence, normal temperature is maximum, and the principle that can be separated out in acid condition, extracts cereal with ethanol and water respectively
Albumen in seed, extract solution are centrifuged, and after acid is heavy after filtrate is enriched with using membrane separation technique, then carry out alcohol precipitation,
Centrifuge, and membrane filtration is used after precipitation is carried out into precipitation, obtain refined beta glucan.But due in alcohol precipitation process
Middle to use ethanol, ethanol is not high to the selectivity of the beta glucan in solution, causes the beta glucan purity of preparation not high, yield
It is low.In addition, ethanol belongs to inflammable explosive article, there can be many requirements to the environment and safety of production plant, increase production cost.
A kind of method for extraction avenabeta glucosan that patent 200610089486.6 is recorded, comprises the following steps：1st, will
Oat bran is at 50-60 DEG C plus water stirs, and adjusts PH8-10；2nd, add protease and hydrolysis oat bran is handled at 45-60 DEG C
Albumen in skin adds；3rd, amylase is handled at 80 DEG C, filtering, obtains supernatant liquid；4th, use molecular cut off for
30000-50000Da ultrafiltration membrance filter, obtains beta glucan solution, and freeze-drying obtains beta glucan product, has purity
85% effect.
The preparation method step that patent 200610097431.X describes a kind of avenabeta glucosan is, using oat bran as original
Material, through crushing, microwave radiation exaraction plus amylase and saccharification ferment treatment, isoelectric precipitation, centrifugation, supernatant concentration, second
Alcohol precipitation, centrifuge and collect precipitation plus water redissolutions, beta glucan enzyme hydrolysis, obtained with significant after spray-drying process
Promote enteron aisle and faecal bifidobacteria, the high-purity avenabeta glucosan product of Bacillus acidi lactici increment effect.
Patent is that a kind of preparation method of 03147786.0 avenabeta glucosan recorded comprises the following steps 1, oat system
It is standby into oat bran, enzyme deactivation；2nd, under the conditions of 45-60 DEG C, add water to stir, be adjusted to PH9-11；3rd, filtrate is collected after separating, is added
Enter ɑ-starch ferment treatment, 70-90 DEG C of holding 1-2 hour；4th, 10-30 DEG C is cooled to, 4.5-5 is adjusted to, is stood after stirring, is sunk
Shallow lake protein；5th, supernatant is centrifuged to obtain, is concentrated by ultrafiltration, isopropanol is added in concentrate, obtains beta glucan gelatinous precipitate；
6th, beta glucan gelatinous precipitate is centrifuged, vacuum drying, obtains beta glucan product.
The method that above-mentioned technical proposal prepares beta glucan using oat or oat bran, mostly chemical method, Enzymatic Extraction,
Extracted using organic solvent, gentle alkali extraction method and saturation sulfuric acid be by precipitation.These methods are required for introducing organic solvent, separation
Product afterwards has chemical residual, and water consumption is larger, and wastewater treatment capacity is big.Also the technical scheme having using gel chromatography separation and
The methods of ultrafiltration membrance filter, but all because cost height is only applicable to laboratory operation, industrialized production can not be carried out.Utilizing swallow
There is starch, protein and insoluble diedairy fiber during wheat bran skin extraction beta glucan to discard with waste material, causes
The loss of nutrient in oat.Oat starch, oat egg white matter and insoluble diedairy fiber also have excellent nutrition and processing
Characteristic.If using starch, protein and dietary fiber only as the accessory substance in avenabeta glucosan extraction process without being subject to
Make full use of, not only cause actual production inefficiencies, high expensive, can also bring serious environmental pollution.Therefore, it is of the invention
Nutrient synthesis in oat is used the angle extracted and produced from full constituent.
The content of the invention
The present invention is a kind of from oat bran so as to provide in order to solve the comprehensive utilization development problem for improving oat bran
The method that middle extraction prepares avenabeta glucosan nutrient powder, dietary fiber micro powder and avenin.
A kind of coproduction of the present invention makes avenabeta glucosan nutrient powder and the method for dietary fiber micro powder, its technical scheme bag
Include following steps：
