Whey and its valorization using Biorefinary: A review

Abstract

Whey is a dairy product, which was thought to be less valuable and was used as a feed for animals or as a source of surplus. In view of that, in overall world, more than 145 million tons of whey is produced, every year, the need for fresh ways to use whey can be esteemed. In current years, numerous studies have been shown about the significance of the properties and nutritional value of whey and its ingredients. Whey is disposed of in the trenches without any effective treatment, which raises the environmental issues. Another use of whey has been used to decrease the adverse effect that is produced on the environment. These uses are creation of relatively inexpensive raw materials, generation of energy and the extraction of macromolecules used in the industries. The integral use of waste at the bottom of the biorefinery scheme foreshadows another potential usage of the generated waste. The main purpose of this review is to elaborate the use of biorefinery for commercially available nutrients in the milk whey.
