Whey protein concentrate (WPC) is a food ingredient made from whey (Milk serum). Confectionary, ready-to-eat cereals, nutritious bars, and sports beverages all include them to increase nutritional value.
Aim: The main of this study was to evaluate the study of the Prepared whey protein concentrate from milk serum and determination of the functional group , antioxidant activity and it sensory evaluation.
Methods: the functional group was determined by the using FT-IR spectroscopy and the antioxidant activity was determined by the scavenging free radial method by using DPPH and observed under spectrophotometer. The sensory evaluation was done by the well trained panellist.
Result: FT-IR spectroscopy reveals the functional group by showing the high and sharp peaks. The highest peak was 3524cm-1 (O-H stretching i.e., hydroxyl group) and the lowest peak was 466cm-1 (S-S stretching i.e. aryl sulphide group). The antioxidant activity was shows that scavenging of free radicals (DPPH). Whey protein scavenges about 50% of free radical at 10mg/ml concentration. The sensory evaluation shows that acceptability of prepared whey protein concentrate is more than that of whey protein isolate.
