Analysis of physiochemical properties of denaturalized hydrolyzed gelatin——emulsify ability and water-solubility properties

surface properties and water-solubility properties of the denaturalized hydrolyzed gelatin were studied in this paper. Emulsify ability and stability of denaturalized hydrolyzed gelatin solution became higher with higher concentration. Compared with hydrolyzed gelatin solution, denaturalized hydrolyzed gelatin solution's emulsify ability descended, but emulsify stability ascend. pH and ion strength had significant effect on denaturalized hydrolyzed gelatin water-solubility, but temperature not.
