ABSTRACT:
Hydrogenated pullulan is produced by the reaction of an aqueous solution of pullulan with hydrogen gas under pressure in the presence of suitable catalysts until the reducing property of the solution disappears. The hydrogenated pullulan is much more resistant to heat than pullulan and its aqueous solution hardly loses viscosity and is not colored under heat treatment. The hydrogenated pullulan is much less absorbable by the intestinal walls than pullulan so as to reduce more effectively the caloric value of foods when it is mixed with foods. Shaped bodies such as films, sheets, plates, capsules, containers, coatings and fibers are readily prepared in a conventional manner. The films are practically impervious to atmospheric oxygen and suitable as packaging material.
