Description
Technical field
The present invention relates to a kind of processing technology of highland barley product, relate in particular to a kind of technology of from highland barley, extracting multiple product continuously.
Background technology
Highland barley is a kind of of barley, claims hull-less barley, highland barley again, in Tibet, Qinghai one band common name highland barley.It is people from Tibetan a staple food crop, can make zanba, roasted qingke barley flour and barley wine with it.Long-term sown area of highland barley and total output account for 55～60% of total sown area of Tibet grain and gross output respectively, and gross output is about 600,000 tons.Highland barley contains abundant beta glucan, is the highest crop of beta glucan in the wheat crops in the world; Also contain dietary fiber, amylopectin, protein, rare nutritional labeling in the highland barley as containing thiamine (vitamin B1), riboflavin (vitamin B2), niacin, vitamin E, these materials are grown promoting health all has positive interactively; The mineral elements such as inorganic elements calcium, phosphorus, iron, copper, zinc and trace elements of selenium that contain the multiple beneficial health.Highland barley has rich nutrient contents, therefore has abundant nutritive value and outstanding medicines and health protection effect.In the Qinghai-Tibet Platean of high and cold anoxic, be no lack of the centenarian why, this and normal food highland barley, the medical health care function effect outstanding with highland barley is undivided.Put down in writing according to supplement to the Herbal: highland barley, during the therapeutic method to keep the adverse qi flowing downward is wide, strong lean power, dehumidifying sweating, antidiarrheal.Tibetan medicine's ancient books and records " brilliant pearl book on Chinese herbal medicine " more highland barley as a kind of important drugs, be used to treat multiple disease.
At present the deep processed product for highland barley mainly concentrates on the beta glucan Study on extraction process, and product is single, although remaining byproduct has very high nutritive value, only as simple feed or give it up, so the utilization rate of highland barley is not high.
Summary of the invention
Technical problem to be solved by this invention provide a kind of fast, safety, the technology of from highland barley, extracting multiple product continuously of highland barley utilization rate of can improving.
For addressing the above problem, a kind of technology of from highland barley, extracting multiple product continuously of the present invention may further comprise the steps:
(1) raw material is handled: select cleaning, dry highland barley for use, after grinding, crossing 200 mesh sieves, obtain highland barley flour and highland barley bran respectively;
(2) extraction of highland barley starch and albumen powder: after at first the highland barley flour of step (1) gained being added alkaline aqueous solution and stirs by 1: 8～1: 40 of its w/v, leave standstill, centrifugal, collect supernatant and sediment respectively; Then with the gained sediment wash to the pH value for neutral, through freezing, dry, must highland barley starch after pulverizing; The sour pH value of regulating the gained supernatant of use at last is 2.5～5.0, and centrifugal back collecting precipitation thing gets the highland barley soy Protein powder with this sediment after drying, pulverizing;
(3) highland barley bran extracts: adopt super critical CO 2 technology to extract or with must highland barley bran behind the little polar solvent cold soaking highland barley bran of step (1) gained;
(4) highland barley Beta-dextran extracts: at first with the wheat bran after the degreasing by 1: 10～1: 40 of its w/v add water through ultrasonic Extraction or boiling, centrifugal after collection supernatant A and residue; In the supernatant A of gained, add 95% edible alcohol then, make its alcohol concentration reach 20～80% by volume after, leave standstill, centrifugal, respectively collecting precipitation thing and supernatant B; Secondly collected sediment must be contained the highland barley Beta-dextran powder after drying, pulverizing; At last collected supernatant B is obtained containing highland barley flavone, amino acid whose concentrate after concentrating recovery ethanol;
(5) highland barley water insoluble fiber albumen powder: the residue of step (4) gained is obtained highland barley water insoluble fiber albumen powder after oven dry, ultramicro grinding.
