Abstract:
    This invention relates to a method for purifying a gelatin solution obtained in a continuous process from raw material consisting of fresh defatted bone material from pig, cattle, sheep or chicken, which method comprises the steps of grinding the raw material, optionally with addition of water, mixing the ground raw material with more water to form a slurry, subjecting the slurry, in optional order, to an adjustment of the pH to 2.4-3.9 and to an adjustment of the temperature to 90-125 DEG C and maintaining these conditions for a time of 90 s to 1020 s. The slurry is then separated into a liquid phase and a solid phase, the pH is adjusted to 6.0-7.0, floccules formed are separated and the solution is clarified by filtration. This invention further relates to a gelatin obtained according to this method.
