Abstract
The invention relates to a method for preparing soybean hull water-soluble dietary fibers. A preparation process comprises the following steps of: (1) grinding soybean hulls; (2) adding water into the ground soybean hulls, stirring, preserving heat, cooling to room temperature, performing centrifugal precipitation, removing sediments and collecting filtrate; (3) adding hydrogen peroxide into the obtained filtrate for de-coloring; (4) adding heated and de-colored solution into solution of cellulase, preserving heat, performing centrifugal separation, removing the sediments and collecting filtrate; (5) heating and concentrating the obtained filtrate which contains the soybean hull water-soluble dietary fibers; and (6) adding alcohol into concentrated solution obtained in the step (5), precipitating and centrifuging to obtain wet soybean hull water-soluble dietary fibers, refrigerating, drying and grinding so as to obtain the water-soluble dietary fibers. The soybean hull water-soluble dietary fibers prepared by the method has the characteristics of sufficient and readily available raw materials, industrialized production, no addition of any chemical reagent in a production process, accordance with the requirement of natural food, functionality, convenience, high purity and low cost.
Description
Technical field
The present invention relates to a kind of soybean skin water-soluble dietary fiber preparation method, specifically be meant with the soybean skin to be the method for a kind of water-soluble dietary fiber of feedstock production.
Background technology
Water-soluble dietary fiber is to be made up of multiple sugar such as galactolipin, arabinose, galacturonic acid, rhamnose, aldopentose, trehalose, glucose; Its structure is for being main chain with the rhamnose galacturonic acid; On side chain, be combined with galactan and araban; Molecular weight between 5kDa and 100kDa, the similar pectin of structure.
Water-soluble dietary fiber is a kind of bioactivator; Has the liver of reduction cholesterol function; Have the effect of the two qi factors of oligosaccharides (compound sugar) and the activity of regulating intestinal bifidobacteria, have good oil absorption and water imbibition, its solubility property is fine; And its solution viscosity is very low, and it is one of good natural material of health foods such as preparation fat-reducing.On the other hand, the soybean skin water-soluble dietary fiber still is the emulsion stabilizer of function admirable, is the stabilizing agent that beverage industry presses for, and it also can be applicable to contain water-soluble fibre beverage and bakery such as high fiber bread, high-fiber biscuits etc.
But the present method of still not having the water-soluble dietary fiber that dna purity is high from soybean skin effectively, performance is good, cost is low can not satisfy the demand that food service industry is produced.
Summary of the invention
The objective of the invention is provides the soybean skin water-soluble dietary fiber preparation method that a kind of purity is high, performance is good, cost is low in order to solve the deficiency that above-mentioned technology exists.
Preparation process of the present invention is following:
(1) earlier soybean skin is crushed to 60～200 orders;
(2) learn from else's experience and be crushed to 60 orders～200 purpose soybean skin 1000g; Add water 20～30kg, under the rotating speed of 60～100r/min, stir 8～12min, under 100～130 ℃ of temperature, be incubated 1～2h; After reducing to room temperature; Under the rotating speed of 5000r/min, carry out centrifugation 5～10min, remove sediment, collect filtrating;
(3) in gained filtrating, adding mass percent concentration is that hydrogen peroxide solution 5～30g of 25～30% decolours, and bleaching temperature is 60～80 ℃, bleaching time 1～2h;
(4) will adding solution behind the heat decoloring, to add 0～20g mass concentration be 20～50% cellulase solution, under 45 ℃～65 ℃ condition, and insulation 1～2h, centrifugation 5～10min removes filter residue under the rotating speed of 5000r/min, collects and filtrates;
(5) gained contains soybean skin water-soluble dietary fiber filtrating, and heating is concentrated into solid content 4～10% under 65～100 ℃ of temperature;
(6) in the said concentrate of step (5), add 2～4 times to the alcohol of concentrate volume, alcohol concentration is 95%v/v; Deposition 1～2h; Under the rotating speed of 5000r/min, carry out centrifugal 5～10min, obtain wet soybean skin water-soluble dietary fiber, at-20 ℃ of temperature freeze drying 12～24h; Be crushed to 150～250 orders then, make water-soluble dietary fiber content greater than 68.0%, color and luster for white or light yellow, moisture less than 7% dry powder.
Another kind of drying means is that step (5) gained concentrate is carried out spray-drying, also can make water-soluble dietary fiber content greater than 68.0%, color and luster for white or light yellow, moisture less than 7% dry powder.
With respect to prior art, the present invention has following advantage:
(1) water-soluble dietary fiber of existing plant origin mainly contains big bean dregs, wheat bran and rice bran water-soluble dietary fiber etc.; Its Main Ingredients and Appearance molecular weight is greater than 100kDa; Contain more fat, sugar and protein in the raw material; So contain more impurity in the final diet fiber product, influenced performance of products.Compare with existing water-soluble dietary fiber, the prepared soybean skin water-soluble dietary fiber performance of the present invention is better.
(2) the prepared soybean skin water-soluble dietary fiber of the present invention, total water-soluble dietary fiber content greater than 68%, crude protein less than 7%, crude fat is less than 0.2%, adding in the food as food ingredient can not influence flavours in food products.
The raw material abundance of the prepared soybean skin water-soluble dietary fiber of the present invention is easy to get, and can form suitability for industrialized production, does not add any chemical reagent in process of production, meets the requirement of wholefood, possesses the characteristics of functional, convenience, the high and low cost of purity.
