The effect of calcium-binding components on calcium removal during electrodialysis
Original language description
Acid whey is a side-stream from the production of skyr, Greek yoghurt, quark and cottage cheese. It contains high concentrations of valuable minerals, which are essential in the human diet such as calcium. Electrodialysis has recently shown to be an efficient way to isolate charged components from acid whey, however, its composition highly affects the demineralization degree (Nielsen et al., 2021). Acid whey contains calcium-binding components such as citrate, lactate, gluconate and sugars that have different affinities to calcium and consequently influence the removal of calcium during electrodialysis. This study investigates the removal of calcium ions in model solutions containing lactose, glucose, glucose/galactose mixture, lactate, gluconate or citrate by electrodialysis in order to identify the importance of bounded and free calcium on the efficiency of demineralization. The effect of pH and concentration are also evaluated for selected calcium binding components.
