Production of whey component concentrates would transform the waste material into product with high nutritional health and technological values. The remaining water is free of organic matter with zero BOD. Thermal stability of isolated lipid-protein whey fraction, using the Differential Scanning Calorimetry (DSC) method, was investigated in this study. From results obtained (thermodinamical parameters of thermothropic lipid phase transitions and thermodinamical parameters of protein unfolding) it can be suggested that dominant lipids in whey fraction are phospholipides, and most abundant protein component is beta-lactoglobulin. Obtained lipid-protein fraction is valuable natural bioactive lipid-protein complex.
