Possibilities of Whey Utilisation

Over the past decades, many researchers have studied the economical possibilities of whey utilisation, primarily how to unwanted by-product converted into a valuable raw material. This paper gives an overview of whey utilisation possibilities. Traditionally, whey (sweet and acidic) is usually dried into powder; however, considering other processing options to improve the economic value such by-product, whey could be utilised, for example, in fermentation, production of soft drinks, production of Whey Protein Concentrate (WPC) and whey protein isolate (WPI), fractionation of certain protein components, such as isolation and purification α-lactalbumin (α-la) including specific peptides, and production lactose, lactic acid and bioethanol. This review provides most recent developments.
