UHT Treatment of Milk and Dairy Products

Abstract

Global consumptions of Ultra-high-temperature (UHT) treated milk and dairy products are on the increase. The UHT treated dairy products are mainly custard and high protein beverages. Milk protein ingredients, e.g. milk protein concentrate (MPC) or isolate (MPI) or milk casein concentrate (MCC) or whey protein concentrate (WPC) or isolate (WPI) are typically added into bovine milk to enrich the protein component of UHT beverages, or to water to make a protein-based beverage. The main reason for increased consumption UHT treated milk and dairy products lies in the fact of its long shelf-life at ambient temperature storage. At present the shelf-life of UHT treated milk and dairy products at ambient temperature storage is 3-9 months.
