Abstract

Effect of adding whey protein concentrate (WPC), β-Lactoglobulin (β-LG) and alfalactalbumin (α-LA) on the functional properties of Whipped cream was examined. Obtained results showed unchangeable values of pH, the highest pH was found when skim milk powder was used compared with other treatments. Higher overrun (%) was also found when β-Lactoglobulin (β-LG) and alfalactalbumin (α-LA) were incorporated in whipped cream than whey protein concentrate (WPC). Samples showed changeable values of whipping time .The sensory evaluation   showed that treatment  with alfalactalbumin (α-LA)was of the most acceptable flavor body & texture and appearance, as compared with other treatments .
