PROBLEM TO BE SOLVED: To provide a method for producing degraded gelatin powder and degraded gelatin powder, in which gelling ability under cooling can be arbitrarily determined only by adjusting the concentration of the sol, and which has a new gel characteristic of low jelly strength not achieved by known gelatin and degraded gelatin, is readily soluble in cold water and can eliminate a heating step, whereby deterioration of degraded gelatin and additives by heating can be prevented and energy can also be saved. SOLUTION: The method for producing degraded gelatin powder includes obtaining degraded gelatin by hydrolyzing gelatin to an average molecular weight of 10,000-30,000 or hydrolyzing gelatin so that 15 wt.% sol prepared by dissolution in water at 40°C has viscosity of 30-90 mP, and drying sol containing the degraded gelatin without causing gelling to form powder. Sol prepared by dissolving the degraded gelatin powder in water does not turn into gel at 4°C in ≤1.0 wt.% concentration but turns into gel in ≥6.0 wt.% concentration. The degraded gelatin powder is readily soluble in cold water at 5-10°C. COPYRIGHT: (C)2009,JPO&INPIT
