PROCESS FOR ISOLATING LACTOFERRIN AND LACTOPEROXIDASE FROM MILK AND MILK PRODUCTS, AND PRODUCTS OBTAINED BY SUCH PROCESS

摘要

The invention relates to a process for isolating bioactive proteins such as lact operoxidase and lactoferrin from milk and/or milk derivatives, characterized by the steps of: a) adsorbing said proteins to a cation exchanger by passing the milk or the milk derivative over the cation exchanger at a high superficial velocity (more than 5 00 cm per hour) and a high liquid load (100-600 bed volumes per hour); b) eluting these proteins, separately or simultaneously, by elution with one or more salt solutions, so as to form one or more eluates, optionally followed by c) drying of the said eluates. The invention further relates to products obtained by this process.
