Effects of ozone on functional properties of proteins

► Ozone treatment resulted in oxidation of proteins with altered functional properties. ► Ozone in the form of gas and aqueous phase was applied on the proteins. ► Foaming stability and activity of the proteins increased with ozone treatment. ► Ozonation affected solubility and emulsifying properties of proteins negatively. ► Ozonated dilute emulsions exhibited more liquid like behaviour at low frequencies.
