In this paper ten symbiotic starter cultures for yogurt production were examined for their coagulation time, titratable acidity, pH at the moment of coagulation. Their maximum rate of acidification was also determined by model of fermentation kinetics. Three starter cultures were selected for production of Vietnamese yogurt. With the selected starter culture, yogurt from natural milk and reconstituted whole milk was obtained. Their coagulation time, acidity, maximum rate of acidification and rate of acidification during storage of product were studied. As a result of this study and mathematical modeling, we concluded that maximum rate of acidification at moment of coagulation and during storage was affected by the type of milk used in yogurt production.
