Ovalbumin is a food-grade major protein of egg white (~54% of total albumen protein), a glycoprotein of 385 amino acids with exceptional foaming, gelling and heat-coagulation properties.We supply bulk Ovalbumin sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Ovalbumin is widely used in immunology standard protein, pharmaceutical formulations, high-protein sports nutrition products, encapsulation and aeration.
Ovalbumin is isolated from fresh egg white via salt-precipitation, ion-exchange chromatography or membrane filtration, followed by freeze or spray drying.
Research-grade ovalbumin (≥98% purity) is used in allergen challenges and vaccine adjuvants, while food-grade ovalbumin (≥85% purity) is used in high-protein foods, sports nutrition, and edible films.
