Demineralised whey powder is a dairy product obtained by processing whey formed during the production of cheese from milk. The demineralisation process ensures that minerals are removed from the product. This process usually involves reducing minerals such as sodium, potassium and calcium. Demineralised whey powder is characterised by a low mineral content as well as protein, lactose and other nutritional components. Due to these properties, it is particularly used in sports nutrition and infant formulas.
