The invention relates to methods of making carbohydrate and polyol esters suitable for use as plasticizers for polymer compositions. The invention also relates to plasticized polymer compositions comprising such carbohydrate and polyol esters. The invention also relates to articles prepared from such plasticized polymer compositions. The invention further relates to methods of using these compositions.

Polymers useful as catalysts in non-enzymatic saccharification processes are provided. Provided are also methods for hydrolyzing cellulosic materials into monosaccharides and / or oligosaccharides using these polymeric acid catalysts.

The present invention herein provides a chitosan-containing polysaccharide and a method for the preparation thereof as well as a medicine and a food containing the polysaccharide.The chitosan-containing polysaccharide is prepared by a method comprising the steps of heat-treating a fungus in a concentrated aqueous caustic alkali solution; subjecting the resulting solution to a solid-liquid separation treatment; dissolving the resulting solid contents in an aqueous organic acid solution; adding, to the resulting solution, an alcohol or a caustic alkali to thus form precipitates; washing the resulting precipitates; and then drying them. This chitosan-containing polysaccharide is a compound in which homopolymers of glucosamine are linked with glucan through covalent bonds; it has a molar ratio of glucosamine and glucose constituting the polysaccharide ranging from 1:5 to 5:1; it has a molecular weight of about 150,000; and it does not contain any β(1→3) bonds, but comprises β(1→4) bonds and β(1→6) bonds. The polysaccharide is free of any protein and reducing polysaccharide. The chitosan-containing polysaccharide is effective for the treatment or prevention of any diseases originated from living habits or customs such as hypertension and diabetes.

This monosaccharide production method is a method for producing monosaccharides from biomass having a first step 3 in which a raw material biomass is pretreated in 65 to 85 (w / w) % sulfuric acid at a temperature of 30 to 70° C., and a second step 4 in which the first step treatment product pretreated in the first step is subjected to saccharification treatment in 20 to 60 (w / w)% sulfuric acid at a temperature of 40 to 100° C.
