Whole milk was preconc. for cheesemaking by ultrafiltration (UF). The UF concentrate was heat-treated to induce a complex formation between casein and whey protein to increase cheese yield. The concentrate was heated at 65, 70, 75 or 80 degrees C for 5 min, and whey protein denaturation degree and viscosity were determined. It was found that increasing the temp. from 75 to 80 degrees C resulted in too high viscosity values of the concentrate.
