Abstract
Milk protein concentrate (MPC) powder is produced from skim milk by ultrafiltration/diafiltration followed by spray drying. It contains varying amounts of protein up to 85 % (w/w). The use of MPC as a food ingredient is increasing worldwide due to its favorable functional properties and high nutritional value. However, MPC gradually loses solubility upon storage. Generally it is believed that the loss of solubility is linked with conformational modification of protein molecules during processing and storage. Besides, other factors like enthalpy relaxation of amorphous MPC powder during storage and interaction with water may have detrimental effects on the solubility of MPC upon ageing. This review highlights some underlying molecular mechanisms of protein denaturation that induce solubility loss in MPC powder.
