Abstract: Rheology properties and thermodynamics properties of the denaturalized hydrolyzed gelatin were studied in this paper. Results showed that the denaturalizing temperature range of denaturalized hydrolyzed gelatin became narrower andenthalpy variety was higher than that of hydrolyzed gelatin. Viscosity of denaturalized hydrolyzed gelatin solution became higher with higher concentration, but solution had good fluidity even if the concentration was 30%. Temperature had significant effect on the viscosity, and the relativity accorded with Arrhenius model: lgη =lgA+Ea/2.303RT. Denaturalized hydrolyzed gelatin solution appeared to be a shear thinner liquid state when the shear rate was at lower range, but when the shear rate was above 30 Pa·s, it became Newton liquid.

Key words: denaturalized hydrolyzed gelatin, physicochemical property, rheology property, thermodynamics property
