Method of producing microcrystalline cellulose-containing compositions

An MCC product characterized by uniformly dispersed micro-particle cellulose produced by a method comprising the following steps:

• (a) hydrolyzing cellulose-containing raw material with a catalytic system comprising at least one acidic catalyst in the presence of at least one process additive at about 0.1 to 10 catalytic system/cellulose weight ratio;
• (b) neutralizing said acid with one or more precipitator in the manner that fine particles of insoluble ingredients participates into a MCC containing slurry;
• (c) admixing at least one modifier, and
• (d) homogenizing of the composition so, that an obtained MCC product are characterizing with micron- or submicron-scale particles;
• uniform fractional composition having heterogeneity H-parameter of about 1 to 1.3, developed external specific surface more 1000 m2/kg and high crystallinity of the solid phase, of about 85 to 90%.
