Whey protein concentrate (WPC) are an group of whey (Milk serum) based food ingredient. They are used in confectionary product, ready to eat cereals, nutritional bars, and sports beverages. Aim: The main aim of this study was to evaluate the morphological and antimicrobial study of whey protein concentrate after extraction from milk serum. Methods: Proximate analysis was done for the determination of protein, ash, fat, and moisture content in whey protein concentrate. Morphological study was done using X-Ray Diffraction (X-RD) and scanning electron microscope. The antimicrobial property of whey protein concentrate was evaluated by Agar well diffusion method. Results: Proximate analysis reveals whey protein concentrates, protein (42%), Fat (4.40), ash (10.37), and moisture (4.27). The whey protein concentrate antimicrobial property also particularly effective against S. aureus (Gram Positive), E. coli (gram negative). SEM and X-RD results reveal micro structure and nature of the compound.
