Abstract
The invention relates to a method for extracting dietary fibers from rice hulls by a continuous ejection liquefaction enzymolysis method, which is characterized in that the rice hulls are taken as the raw materials and the continuous ejection liquefaction enzymolysis method is adopted to prepare dietary fiber products with polydextrose as the main raw material through the procedures of raw material treatment, continuous ejection liquefaction, adsorption and decolorization, drying and the like; the soaking time is 3-7 hours; the diameter of the ground rice hulls is not more than 0.1mm; the temperature suddenly rises to 105-110 DEG C in the procedure of continuous ejection liquefaction; the heating temperature for inactivating enzyme is 105 DEG C; activated carbon is used for adsorption; and the 60-mesh filter screen is used for separation, and the dietary fibers can be obtained. The invention develops an efficient method for extracting dietary fibers. The hemicellulose in the rice hulls is mainly araban, xylan, hemicellulose and xylo-oligosaccharide, and the ingredients can be used for preparing various delicious functional foods by modern methods, such as functional drinks containing multiple cellulose ingredients, cellulose reinforced baked food and various low-calorie and high-fiber functional candies.
Description
Technical field
The present invention relates to a kind of continuous injection Ye Huamei solution and extract the method for rice husk dietary fiber.
Background technology
Dietary fiber is the general dietary nutrient that quilt is digested that is difficult for, and mainly comes from the cell membrane of plant, comprises cellulose, hemicellulose, resin, pectin and lignin etc.The dietary fiber fiber is keeping playing the part of important role on the digestive system health, and absorbing enough fibers simultaneously also can angiocardiopathy preventing, cancer, diabetes and other disease.Fiber can clean wall of digestive and strengthen digestive function, and fiber can dilute and quicken simultaneously removing of carcinogen in the affairs and noxious material, the alimentary canal that protection is fragile and prevent colon cancer.Fiber can slow down digestion rate and rapid drainage cholesterol, so can allow blood sugar and cholesterol in the blood be controlled at optimal level.
In diet healthization, dietary fiber is undoubtedly preferred material, though dietary fiber can not be absorbed by human consumption, dietary fiber has the important physical effect in vivo, is to keep the requisite class nutrient of health.Since dietary fiber prevention human intestines and stomach's tract disease and safeguard intestines and stomach healthy aspect function give prominence to, thereby the good reputation of " cleaning intestinal tract husband " is arranged.The principal benefits of taking in certain dietary fiber every day has: keep digestive system health; Strengthen immune system; Reduce cholesterol and hypertension; Reduce insulin and triglyceride; Defaecation, diuresis, gut purge are good for the stomach; Angiocardiopathy preventing, cancer, diabetes and other disease; Hormone and the reduction cancer relevant in the balanced body with hormone.The main effect of internationally recognized dietary cellulosic has: anti-treating constipation; Be beneficial to fat-reducing; The prevention colon and the carcinoma of the rectum; Prevent and treat hemorrhoid; Reduce blood fat; Improve diabetic symptom; Improve oral cavity and dental functions; Prevent and treat gall stone; The prevention women breast cancer.Although domestic is that the research of feedstock production xylo-oligosaccharide is at the early-stage with cellulosic materials such as rice husk, corncobs, a lot of people have done a large amount of research to this.Extraction cellulose and dietary fiber method commonly used have acid-hydrolysis method, alkali hydrolysis method, hot-water extraction enamel, enzyme hydrolysis method, microwave degradation method.The rice husk dietary fiber is different from soybean dietary fiber product tool anaphylaxis on the market as a kind of brand-new diet fiber product.
Summary of the invention
The unique antianaphylaxis of rice husk dietary fiber, applicable to baby products and allergic constitution people food, the rice dietary fiber will be because self extensive adaptability and antianaphylaxis will substitute the wider soybean dietary fiber of present use.
A kind of continuous injection Ye Huamei of the present invention solution is extracted the method for rice husk dietary fiber, developed a kind of method of extracting dietary fiber efficiently, hemicellulose in the rice husk mainly is araban, wood sugar, hemicellulose, xylo-oligosaccharide etc., more than these compositions can make various good to eat functional foods by modernism again, as contain the drinks of a lot of cellulose components, the bakery product strengthened through cellulose, also have the functional candy of various low in calories, high fibers.
Technical scheme of the present invention:
A kind of continuous injection Ye Huamei solution is extracted the method for rice husk dietary fiber, it is characterized in that with the rice husk being raw material.Adopt continuous injection Ye Huamei solution, handle through raw material, continuous injection liquefaction, adsorption bleaching, it is the diet fiber product of main material that operations such as drying make with the polydextrose.
Raw material is handled and comprised: it is with first rice husk rice husk go-on-go, impurity such as flush away soil block, grass roots that a cleans.B dipping be in warm water .c pulverize the rice husk that in the tailored flour grinding machine, will soak through grinding, cutter cuts .d and sizes mixing to add in the rice husk after pulverizing and select protease 5-25% well, and fully mix thoroughly.
The time of soaking is 3-7 hour.
Diameter≤the 0.1mm that pulverizes.
Continuous injection liquefaction comprises: the liquefaction of a continuous injection: adopt the steam ejection liquefaction equipment of development, the powder slurry is liquefied.Contain powder slurry moment and vapor mixing in injector of protease, temperature rises sharply to and is fit to temperature, finishes liquefaction rapidly, adds high temperature resistant fungal enzyme simultaneously.B insulation: powder starch under the promotion of vapours, sprays in the insulation jar, remains in 95 ℃ the water vapour 90 minutes, makes liquefaction complete, and protein fully condenses.C heats the enzyme that goes out: the powder slurry is promoted by vapours once more, sprays in the pyrolytic tank, and heating loses activity enzyme.
The temperature that rises sharply is between 105-110 ℃.
The temperature that heats the enzyme heating of going out is 105 ℃.
Adsorption bleaching comprises: a filters: filter at the special filtering machine, protein is filtered.Adsorption bleaching of b: coloured impurity and some heavy metals are removed, ash is dropped to original 10%.C separates: different according to dietary fiber with starch sugar strand length, separate with screen pack.
The charcoal absorption of an adsorption bleaching use.Be separated into 60 orders.
General minimum the carrying out twice of adsorption bleaching adsorption bleaching and separating process.
Drying is a drying: air-dry half an hour in triple effect falling liquid film vacuum drier, obtain the dietary fiber powder at last.The b classification: the powder after will pulverizing further screens, and is divided into grade.
Major technique:
1. rice husk is ground into diameter earlier less than 0.1 millimeter small pieces, adds a certain amount of protease, stir into the powder slurry, in warm water, fully soak, pass through the twin (double) screw extruder crush and grind again, original destructurized of raw material, and fully contact with protease.
2. selected thermostable proteinase, formulated powder slurry moment and 110 ℃ of vapor mixing of containing high temperature resistant enzyme, fully effect in the insulation jar again, this method liquefies under high temperature enzyme optimal temperature fully, fully reaction, suitable fully filtration is suitable for serialization and large-scale industrial production.
3. because dietary fiber is a kind of heat sensitive material, easy coloring is heated, therefore separate the back dietary fiber and in triple effect falling liquid film vacuum drier, carry out the vacuum and low temperature operation, the advantage that can bring into play the evaporability height, save energy and reduce the cost, operating cost is low can keep original color of material and composition again the biglyyest.
