Abstract
The invention relates to a method for producing soybean dietary fibers from soybean seed coats. The method comprises the following steps: 1, adding water to crushed or uncrushed soybean seed coats, adjusting the pH value of the obtained solution to 8-14 h, heating the solution to 80-99 DEG C, and carrying out alkali boiling for 1.5-23 h to obtain an alkali boiling slurry; 2, separating the alkali boiling slurry to obtain a solid, adding water to the solid in order to obtain a slurry, adjusting the pH value of the slurry to 6.5-8.5, adding a bleaching agent, stirring the slurry and the bleaching agent, and heating the slurry and the bleaching agent to 90-98 DEG C to bleach the slurry in order to obtain a bleached slurry; and 3, separating a solid in the bleached slurry, washing the solid, drying the washed solid, and crushing the dried solid to obtain the soybean dietary fibers. The preparation method has the advantages of simplicity, wide sources of raw materials, low cost and low device requirements, and the fiber content of the soybean dietary fibers obtained in the invention exceed 90%.
Description
Technical field
It is more particularly to a kind of to produce soybean dietary using soybean peel the invention belongs to the preparation field of soybean dietary fiber
The method of fiber.
Background technology
Soybean dietary fiber refers to the non-starch class polysaccharide that can not be digested by human body alimentary canal enzyme, including cellulose, half
Cellulose, oligosaccharide, lignin etc..Its effect is deeply gradually recognized with scientific research by people, and present people claim it
It is " the 7th nutrient ", recent studies have shown that, increasing the dietary fiber content in diet can reduces the generation of coronary heart disease, mitigate length
Damage of the phase heavy drinking to pancreas, reduces the content of Blood Cholesterol, absorbs the dietary fiber of proper proportion, can improve
The absorption function of intestines, prevents colon cancer.
Country's soybean dietary fiber is produced using protein production accessory substance bean dregs at present, the soybean meals for being produced
Fiber content is all below 90% in food fiber.Soybean peel is the accessory substance of soybean grease processing enterprise, and annual output is up to
More than 500 ten thousand tons, in addition to a small amount of feed for being used for ruminant, much all cannot sufficiently utilize.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of method that utilization soybean peel produces soybean dietary fiber,
The method is simple to operate, and the fiber content of resulting soybean dietary fiber is more than 90%.
The method that a kind of utilization soybean peel of the invention produces soybean dietary fiber, including：
(1) added water in the soybean peel crushed or do not crush, adjust its pH value after 8-14, to be heated to 80-99 DEG C, carry out alkali
Boil 1.5-23 hours, obtain the slurries after soda boiling, wherein most non-cellulosic material dissolves, and solid content is mainly by cellulose group
Into；
(2) slurries after above-mentioned soda boiling are separated, solid content is obtained, above-mentioned solid content is added water and is formed slurries again, regulation slurries
PH value is 6.5-8.5；Bleaching agent is subsequently adding, is stirred, be heated to 90-98 DEG C, bleached, the slurries after must bleaching；
(3) solid content in the slurries after above-mentioned bleaching is separated, washing dry, pulverize, and obtain final product soybean dietary fiber.Step
(1) soybean peel described in is in advance by washing.
PH value is adjusted using NaOH in step (1).
Step first washs solid content with clear water in (2), and then add water forms slurries again.
Step (2) middle phosphoric acid, watery hydrochloric acid or dilute sulfuric acid adjust the pH value of slurries.
Bleaching agent described in step (2) is hydrogen peroxide, chlorine, sodium hypochlorite or sulfurous acid.
The consumption of the bleaching agent described in step (2) is 0.1-5 times of soybean peel quality.
Bleaching agent described in step (2) is hydrogen peroxide, and its consumption is 0.1-5 times of soybean peel quality.
The bleaching time bleached described in step (2) is 0.5-5 hours.
Fiber content is >=90% in the soybean dietary fiber obtained in step (3).
Soybean peel and water are mixed to form slurries, slurries under highly basic effect, non-cellulosic material dissolving, by filtering or
Centrifugation goes out cellulose；The cellulose isolated adds clear water to stir to form slurries, and slurry pH value washing is for neutral to weak base
Property, stir, hydrogen peroxide is added, heating promotes bleaching and non-cellulolytic, and the product for ultimately forming is separated, institute
The solid content for obtaining obtains soybean dietary fiber product of the content of cellulose more than 90% through drying and crushing.
Beneficial effect
(1) preparation method of the invention is simple, and extensively, low cost, the requirement to equipment is low for raw material sources；
(2) fiber content of the soybean dietary fiber obtained by the present invention is more than 90%.
