Abstract

PROCEDE POUR LA COAGULATION DU LAIT PAR DES SUBSTANCES POLYMERES. LA PRESENTE INVENTION DECRIT UN PROCEDE POUR LA COAGULATION DU LAIT QUI CONSISTE ESSENTIELLEMENT A METTRE EN CONTACT LE LAIT A COAGULER, AFIN D'EN RECUPERER LES PROTEINES, AVEC UNE SUBSTANCE POLYMERE PURE OU MIXTE QUI A UN PH DE 3 A 7, LE LAIT A COAGULER ETANT AMENE A UN PH COMPRIS ENTRE 5 ET 8 ET A UNE TEMPERATURE COMPRISE ENTRE -10C ET 80C. LA SUBSTANCE POLYMERE PROVENANT DE LA COAGULATION DU LAIT DOIT ETRE AU MOINS ASSEZ SOLUBLE DANS L'EAU ET DOIT AVOIR, DANS UNE SOLUTION AQUEUSE A PH EGAL OU SUPERIEUR A 5, UN EXCES DE GROUPES FONCTIONNELS IONISABLES CHARGES POSITIVEMENT PAR RAPPORT AUX GROUPES FONCTIONNELS IONISABLES CHARGES NEGATIVEMENT. LES POLYMERES SYNTHETIQUES UTILISABLES SONT LA POLYETHYLENE-IMINE, LA POLY-ORNITHINE, LA POLYVINYLPIRIDINE, LA POLYVINYLAMINE ET LES POLYMERES NATURELS SONT LES PROTEINES ET LES POLYSACCHARIDES SOLUBLES DANS L'EAU. UTILISATION DE CE PROCEDE POUR RECUPERER PLUS DE 90 DES PROTEINES DU LAIT.
