Both tofu and cheese are made from curds obtained from the coagulation of soy milk and dairy milk respectively. However, soybean curds are formed from the chemical destabilization of the micelles (using calcium sulfate, magnesium sulfate, etc.) allowing protein bonding while cheese curds are created from the enzymatic (rennet) hydrolysis of casein into para-casein. The bean curds are then simply pressed to produce tofu and thus bland and highly perishable, like unaged cheese, while fermented bean curd, like aged cheese, is
