In the dairy industry the stability of dairy proteins toward heat treatment is a major processing issue. Heat treatment of whey proteins to temperatures above 70°C causes denaturation, which in turn leads to protein aggregation. This can result in excessive thickening or gelling during processing of the dairy product and later, upon storage. Whey proteins (WPs) have distinctive nutritional and functional properties that make them unique food ingredients. It is widely used as an ingredient in many traditional and novel food products primarily because of its high nutritional value and some desirable functional properties in whey protein products. This paper reviews the several approaches such as application of transglutaminase, addition of chelating agents, carbohydrates, hydrophobic compounds, H2O2, chitosan and novel methods such as high hydrostatic pressure, ultrasonication to reduce denaturation and aggregation of whey proteins during heating and to produce heat stable whey protein products. | Different approaches to improve thermostability of Whey Proteins: A review
