Abstract
The present invention relatest o the purification of oligosaccharide in which the oligosaccharide solution is passed through filter, high pressure pump, then fed into ultrafiltration membrane tube to remove large molecular impurities, pigment, and then fed into nanometer filtration membrane tube to separate oligosaccharide and monosaccharide. The use of member filtration technology fulfills the purification of oligosaccharide by physical method. Said method is convenientin operation, safe and reliable and is suitable for the purification of different types of oligosaccharide.
Description
The present invention relates to a kind of purification method of oligosaccharide, is that polymerization sugar and the oligose that the monose in the oligose, pigment and the polymerization degree is higher carries out isolating method
The technology of producing at present oligose generally all needs to join uses that cooperatively interact of finings, discoloring agent, makes complex manufacturingization, the production cost increase that consumptive chemical assistant makes.In addition, in existing technology, can't get rid of the monose of not participating in polyreaction, make the oligose product purity to improve.The present invention is directed to present traditional technology and develop a kind of purification method of oligosaccharide that does not use chemical assistant with physical method.
The object of the invention is, the development purification method of oligosaccharide be with oligosaccharide solution through 10 μ strainers, 3 μ strainers, high-pressure pump, enter ultrafiltration membrane pipe, slough impurity, the pigment of larger molecular weight, enter the nanofiltration membrane pipe then and carry out separating of oligose and monose, utilize membrane separation technique to realize the purifying of physical method oligose.Its core is according to the deep layer grafting or the modification of the molecular size of various pigments, polymerization sugar in the oligosaccharide solution and nanofiltration membrane surface macromolecular material, makes it have the chemical separation function.When oligosaccharide solution by film when surface, various absorption, decolour, be separated in the film and carry out.Finish decolouring simultaneously, get rid of more macromolecular polymerization sugar, through the nanofiltration membrane pipe unreacted monose is separated then.This method easy construction, easy to operate, safe and reliable is applicable to various types of oligose purifying.
Purification method of oligosaccharide of the present invention, this method be with oligosaccharide solution through 10 μ strainers, 3 μ strainers, high-pressure pump, enter ultrafiltration membrane pipe, slough impurity, the pigment of larger molecular weight, enter the low sugar soln of purifying behind the nanofiltration membrane pipe then, separate water outlet and monose; Ultrafiltration membrane pipe, nanofiltration membrane Guan Jun open the organic polymer compound film sheet by 5-10 and form, and adopt scroll-type system film forming pipe; The organic polymer compound film sheet is to be made by the aromatic polyamides of polysulfone material or high-crosslinking-degree; The related oligose of this method comprises: soybean starch, W-Gum, sweet potato starch etc.
Referring to accompanying drawing
Fig. 1 is a process flow sheet of the present invention
Further specify and provide embodiment below in conjunction with accompanying drawing
At first the storage tank that oligosaccharide solution will be housed is opened gate valve, make sugar soln successively by 10 μ strainers, 3 μ strainers, sugar soln after will being filtered by high-pressure pump is again sent into by 5-10 and is opened in the scroll-type ultrafiltration membrane pipe that the organic polymer compound film sheet forms, the effective pore radius on film surface has stoped passing through of various pigment moleculars and bigger oligosaccharides molecule and other macromolecular substance, and unsanctioned all kinds of molecular substances are discharged from the shunting position of film pipe with liquid effluent.See through liquid and enter storage tank, pump into the nanofiltration membrane pipe once more by high-pressure pump, when sugar soln is surperficial through film, because the prevention of effective pore radius, film surface and film surface polarity molecule functional group's affinity interaction, unreacted monose is together drained through fenestra with water in the sugar soln, the oligosaccharides molecule that is trapped enters in the receiving tank with flow, further concentrates the purifying standard that reaches.
