ABSTRACT

A nondestructive method to quantitate the coagulation process has been developed and used to obtain kinetic data on the heat-induced gelation of egg albumen. It involves continuous monitoring of the force exerted by the gel as coagulation takes place and requires only one sample to observe the total process. From the information on the maximum force exerted by the gel, rate constants, Z values, and activation energies were calculated. This approach was applied to evaluate other coagulation processes such as the enzymatic coagulation of milk and the gelation of gelatin by cooling.
