Technological breakthrough of the agrarian-and-food innovations in dairy case for example of universal agricultural raw materials. Ion exchange

Aim. Consideration of the process of membrane technology – ion exchange by directed and controlled processing of whey and its filtrates through specially selected selective sorbents – ion exchange resins (ionites). Discussion. The essence of ion exchange lies in the fact that, under certain conditions, an exchange of ions takes place between a solid (ion-exchange resin) and a solution containing undesirable impurities, as a result of which the solid sorbs the ion from the solution, giving it also an ion less harmful to the basic manufacturing. Ion exchange allows to remove some undesirable mineral and organic compounds of the ionic and molecular origin of whey and its filtrates (permeates). Conclusion. The use of ion exchange for the processing of universal agricultural raw materials is recommended for the production of high-quality milk sugar (lactose) by spray drying, dry whey for baby food, synthesis and demineralization of lactulose syrups; sorption-desorption of whey proteins.
