Abstract
The invention discloses a method for decolorizing full water-soluble soybean glycoprotein, which belongs to the field of food industry. The full water-soluble soybean glycoprotein not only has a plurality of functions of dietary fiber, but also has emulsibility, emulsification stability and a plurality of other superior functional characteristics. However, the dark color, namely the dark brown of the prior domestic full water-soluble soybean glycoprotein seriously affects the development and utilization of the full water-soluble soybean glycoprotein. The method takes granular activated carbon as decolorizing media and utilizes an integrated separation technique of fluidized beds and microfiltration to decolorize the full water-soluble soybean glycoprotein. The method is characterized in shortened decolorizing time and high efficiency.
Description
Technical field
This paper relates to a kind of decoloring method of full water-soluble soybean glycoprotein, belongs to field of food industry.
Background technology
Full water-soluble sugar soybean protein is a kind of rising functional oligose class, indigestibility, and calorific value is low, the disease of can not causeing fat; Be again the good breeding material of bifidus bacillus, have a series of physiological functions the human body beneficial.Full water-soluble soybean glycoprotein can be widely used in food, drink production, aspect medicine, the fodder additives tempting application prospect is being arranged.In addition, full water-soluble soybean glycoprotein also has under emulsification and emulsifying stability, the acidic conditions graceful function characteristics such as the stabilization of protein grain, anti-agglutinating value(of coal), film forming properties and froth stabilities.
In the world the development and utilization of full water-soluble soybean glycoprotein is paid much attention to, Japan maintains the leading position in this respect, but correlation technique belongs to corporate secret.Though China starts late, some achievements have also been obtained.The enforcement period of the ninth five-year plan, national functional sugar ultimate production was about 20,000 tons in 2000.But the color and luster of the full water-soluble glycoprotein that China produces is bad, has had a strong impact on the application and the market value of product.Therefore, full water-soluble soybean glycoprotein decoloured to have great importance, and can improve the market competitiveness and the market application foreground of full water-soluble glycoprotein.
Fluidized-bed is that a kind of gas or liquid of utilizing makes solid particulate be in the suspended motion state by the particulate solid layer, the reactor of the promoting the circulation of qi solid state reaction process of going forward side by side or liquid and solid phase reaction process.
The present invention utilizes fluidization and micro-filtration technology integrated, is sorbent material with the activated carbon, and feed liquid enters from the adsorption bed lower end that solid adsorbent is housed, and solid adsorbent is fluidized state in bed.Because solid adsorbent is fluidization in bed, make its back-mixing, has so just improved duration of contact and area between solid adsorbent and the liquid; And with the micro-filtration coupling, realize decolouring rapidly and efficiently.
Summary of the invention
As medium, the integrated isolation technique of fluidized-bed and micro-filtration is decoloured to full water-soluble soybean glycoprotein with granulated active carbon in the present invention.
Technical scheme of the present invention is:
1) the full water-soluble soybean glycoprotein solution of factory is feed liquid.
2) according to solid-to-liquid ratio 0.5%～4% take by weighing granule activated carbon (0.10～0.40mm), join and write down elemental height in the fluidized-bed.
3) regulate flow rate pump, make the expansion of activated carbon highly reach 3～5 times, continue decolouring 0.5～1.0h.
4) with the micro-filtration coupling, obtain product.
Applicable object of the present invention is a full water-soluble soybean glycoprotein.At present, homemade full water-soluble soybean glycoprotein color is dark, and dun has had a strong impact on the development and use of full water-soluble soybean glycoprotein.
The decoloring medium that the present invention uses is a grain active carbon.
The present invention utilizes fluidized-bed, adopts the fluidizing mode to improve the duration of contact and the area of gac and solution.The present invention utilizes fluidized-bed to compare decolorizing efficiency height, efficient height with other decolouring modes.
The present invention utilizes the integrated isolation technique of fluidized-bed and micro-filtration that full water-soluble soybean glycoprotein is decoloured, and carrying out micro-filtration is in order to remove issuable active carbon powder and assurance quality product in the fluid mapper process.
