ABSTRACT:
The invention relates to a process for the decationization of by-products of milk, particularly whey for cheesemaking, by ion exchange, comprising passing the by-product in liquid form successively through a weak cationic resin and then through a strong cationic resin and then regenerating the resins by passing an acid successively through the strong cationic resin and then through the weak cationic resin.
This process enables the strong cationic resin to be utilized to 90% of its capacity and from 30 to 40% of regeneration reactant to be saved. The product obtained serves as an intermediate in the production of lacto-proteins and demineralized lactoserum products suitable for human and animal nutrition.
