Typical DSC denaturation peak associated with thermal denaturation of fully hydrated collagen fibrils from a new goat leather tanned with mimosa-bark extract. T_onset (°C) is defined by the intersection of a line tangent to the steepest section of the leading edge and the baseline of the thermogram. T_max (°C) is the temperature of maximum heat flow. Enthalpy of thermal denaturation, ∆H (J/g), is the area under the endothermic peak. ∆T_1/2 (°C) is the full width at half maximum of the endothermic peak
