Heating induces oxidation and conformation changes of proteins which affect meat products quality and nutritional value. To investigate this system by calculations, according to parameters like iron content or temperature, a stoichio-kinetic mathematical model was built. It consists of many differential equations solved numerically, each representing an elementary chemical reaction or physical phenomenon. The main phenomena taken into account are the iron oxidative cycle, free radicals interactions and protein oxidation and denaturation.
