Abstract

Temperature dependence of reconstituted skim milk coagulation on its initial acidity and concentration of calcium ions is investigated. It is shown that the temperature of milk coagulation decreases with increase of both milk acidity, and ionised calcium concentration in milk. Moreover, there is a possibility to change the temperature of milk coagulation by simultaneous variation of both specified parameters.On the basis of the experimental data some hypotheses are formulated and the physical and chemical model is offered describing heat-acid and heat-calcium milk coagulation within the limits of the uniform scheme.

Keywords

Heat-acid coagulation, thermographic method, calcium ion effect
