Sažetak
Electrodialysis represents an electrochemical separation process which employs ionic selective membranes to remove cations and anions in two separate streams of current and electrolyte flows. An optimization of electro-dialitic process and the adjustment of operational parameters provides to obtain the whey powder with various degree of desalination. The highest desalination effect provides the whey powder with up to 1.70 per cent of ash, whereas the demineralization of 70 per cent means about 3 per cent of ash. It has been pointed out that higher degree of desalination succeeds completely to remove the salty taste of the whey powder. The demineralized whey powder represents a suitable product for confectionery industry and baby food. Initial whey powder has contained 9.55 per cent of ash and seatured distinctly salty taste. There has been developed an efficient industrial electrodialytic process for whey desalination in various degrees of demineralization effects and proved experimentally at a pilot-plante scale.
