<p>The invention relates to a process for the preparation of a gelatine composition with increased gelling and solubility capacities, and to the composition obtained by such process. The process comprises an acid and/or alcaline treatment of pigskin, cattle skin or bones, the aqueous extraction of collagen followed by subsequent steps of filtration, purification, evaporation, cooling, drying and milling. The process includes the incorporation of organic acids and pH regulating salts and preferably neutral salts directly into the resulting gelatine solution before cooling, drying and milling steps.</p> |
