Fortification of cow’s milk with ionic calcium salts such as calcium chloride greatly increases its fouling propensity. As shown in Figure 1, the addition of as little as 0.7 mM calcium chloride makes a marked difference to fouling dur-ing processing at 135 °C. The addition of 0.7, 2.0 and 3.4 mM calcium chloride increased the Ca2+concentrati onin the milk by 0.21, 0.48 and 0.92 mM and decreased the pH by 0.03, 0 .06 and 0.14 units, respectively (Prakash2007). The ethanol stability of the three fortified milk samples was reduced from 83 to 77, 68 and 57%, respectively.Milk with an ethanol stability of
