Abstract

On traite des matières premières contenant du collagène en vue du formage, du filage ou de la liquéfaction du collagène avec utilisation de protéases neutres et/ou alcalines. Après pelanage effectué de la manière habituelle, on soumet la matière première contenant le collagène à une incubation dans une solution contenant des protéases neutres et/ou alcaline : à un pH de 6,5 à 13 en présence d'urée et/ou de guanidine ou d'un sel de guanidine et d'acide, après quoi on désactive les enzymes. Ce procédé permet d'écourter considérablement les durées de traitement, on prépare notamment les gélatines, les colles, les filaments et feuilles de collagène.
