Abstract
The present invention relates to a method for preparing a concentrated polysaccharide mass, in particular a method for preparing concentrated glucan or schizophyllan, in particular a method for redispersing glucan or schizophyllan for producing a ready-to-use mass.
Claims8
A method for preparing a concentrated polysaccharide mass, wherein the method comprises:
- (1) blending the concentrated polysaccharide mass having a polysaccharide concentration [c1] in the range from ≥50 g to ≤800 g of polysaccharide per liter of concentrated polysaccharide mass, to obtain a mash having a polysaccharide concentration [c2] in the range from ≥5 g to ≤50 g of polysaccharide per liter of mash, wherein the blending comprises adding a first dilution liquid, and during the blending a particle size of particles of the concentrated polysaccharide mass is decreased and mixing with the first dilution liquid proceeds;
- (2) homogenizing the mash having a polysaccharide concentration [c2], in order to obtain a homogenized mash having a polysaccharide concentration [c3] in the range from ≥5 g to ≤50 g of polysaccharide per liter of homogenized mash, wherein, during the homogenization, homogenization of particles in the mash proceeds;
- (3) diluting the homogenized mash having a polysaccharide concentration [c3], in order to obtain a diluted homogenized mash having a polysaccharide concentration [c4] in the range from ≥0.05 g to ≤2.0 g of polysaccharide per liter of diluted homogenized mash, wherein the dilution comprises addition of a third dilution liquid,
- wherein the ratio of [c1] to [c4] is in the range from ≥1:30 to ≤1:20 000.
