Consistency variables are introduced by Brookfield viscometer as below,
p=2ηΩdyne/cm2
V=2Ωsec-1
The viscosity of ammonium caseinate solution at 20°C, pH 9.2, depends upon Arrhenius-Duaclau's equation.
The solution immobilizes its solvent to gelation and gives structural viscosity.
When the consistency is between 1013g/100cc, it shows gel-solution and over 13.0g/100cc, the molecular particles associate one another to compose gel-structure.
In low consistency, flow type is Newtonian and in high, plastic.
The higher the temperature, the lower the elasticity and therefore it can be said that it belongs to energy elasticity.
If shearing stress is given instantly, then a constant and continuous rate of shear, relaxation of elastic stress takes place.
Thus, the solution becomes as near as Maxwell liquid which consists of Hookian elasticity and Newtonian flow property.
