Title:
デンプン誘導体の橋かけ及びそれらの製造方法
Document Type and Number:
Japanese Patent JP4674357
Kind Code:
B2
Abstract:
A paste of starch derivative is crosslinked by irradiation with gamma-rays or electron beams in a dose of 0.1-200 kGy. Two different levels of crosslinking are performed; the first is mild crosslinking by irradiation at a low dose of 0.1-1.0 kGy to such an extent that the viscosity of the overall system increases upon immersion in water, and the second is intensive crosslinking by irradiation at a higher dose than 1.0 kGy to produce a gel that is completely insoluble in water.
