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

Abstract

Aim. Consideration of the process of pressure driven membrane technology such as electrodialysis – targeted and operable whey and whey permeate treatment with an aim of demineralization and ash concentration reduction. Electrodialysis use in dairy industry all over the world (as well as in Russia) and allows implementing technological breakthrough in the area of widespread whey application for food and feed supplements of new generation. Discussion. Native whey electrodialysis is a separate branch of pressure-driven membrane technology of molecular-sieve separation which usually applied after defatting, casein clusters separation and also intended for whey permeates (UF, NF, MF, DF) treatment. NF-retentates demineralization is an inherent part of raw materials preparation for supersaturated syrups crystallization and spray drying in production line of food and pharmaceutical lactose. Conclusion. In general, production of dry demineralized whey and its permeates is practically impossible without demineralization by a method of electrodialysis due to high ash concentration.
