Technical field
The invention belongs to food processing technology field, be specifically related to a kind of polymerization soybean polysaccharide and preparation method thereof and application.
Background technology
Water soluble soybean polysaccharide to be a kind of galacturonic acid content be 18% acidic polysaccharose, similar pectin, anionic polysaccharide is belonged to together with pectin, galacturonic acid main chain is dispersed with the tral sugar side chains such as pectinose, its main chain is made up of polygalacturonic acid (GN) and poly-rhamnosyl galacturonic acid (RG), the polymerization degree of β-Isosorbide-5-Nitrae-galactose side is approximately 43-47 residue, and has trehalose to be connected with it with arabinose residues.The Arabic sugar chain of α-1,3-and α-1,5-is connected with rhamnosyl side chain in C-4 position.Some galacturonic acids modify (extent of polymerization is 4 or 7 residues) in C-3 site by xylo-oligosaccharide, and this xylo-oligosaccharide is made up of β-Isosorbide-5-Nitrae-and β-1,2-xylose residues.
Soybean polysaccharide not only has the functional performance that food fibre has, and also has under foamed stability, highly water-soluble, emulsification and stability, anti-caking, high-temperature stable, film forming properties and acidic conditions high-performances such as the stabilizations of protein grain.When adding soybean polysaccharide in protein solution, the acid main chain of soybean polysaccharide is combined with the amino of protein, make whole combination electronegative and mutually repel, prevent albumen particle from contacting with each other and precipitate, compared with other acidic polysaccharose stablizer, soybean polysaccharide also has long neutral side chain, the space structure that albumen particle is larger can be maintained, even if make protein grain can not contact with each other in iso-electric point and precipitate, Here it is soybean polysaccharide is better than other stablizer also can the reason of stabilize proteins in acid condition.
According to investigations, the existing probiotic beverage utilizing soybean soluble polysaccharide on the market, utilize bean dregs to extract Requirement and development trend that soybean water-soluble polysaccharide is current market as the dispersion stabilizer of yogurt drink.But, compare with traditional pectin, that soybean polysaccharide also exists be slightly poor for protein milk beverage stability, relative usage is large, high in cost of production drawback.Therefore, modifying the physical property of soybean polysaccharide is obtain near isoelectric points of proteins, have better dispersion stabilization, more a kind of method of the stablizer of high emulsibility energy.
