Whey, More Than a By- Product

Whey is a by- product of cheese making and casein manufacture is being considered one of the most polluting food by/co-product streams since it has a biochemical oxygen demand (BOD) and the chemical oxygen demand (COD). Whey could cause high environmental damage equivalent to that caused by fecal waste produced by 1900 humans. Whey, often considered as waste, has high nutritional value and can be used to obtain value-added products. Whey is rich with valuable proteins, minerals important for the human organism (Ca, K, Mg, Na, C1, P), certain quantities of water-soluble vitamins and substantial quantities of lactose. One possibility of whey utilization is producing different kinds of nutritive beverages, which continues to attract interest in different parts of the world. The aimed of this study is to review the various technologies available for the production of different nutritive beverages from whey.
