Sodium caseinate (143 g.) (Alanate 155, New Zealand Milk Products) was dissolved in 1500 ml. hot water; this solution was then cooled to room temperature and mixed with the citric acid solution. A slurry of 1110 g. of calcium hydroxide in 1870 ml water was added quickly with stirring to the citric acid-sodium caseinate solution. Within two minutes of mixing, the temperature of the mixture increased from 70° F. to 150° F. A coarse caseinate-coated calcium citrate suspension was obtained that was continually stirred for about 45 minutes. During this period, the temperature dropped to 100° F. The suspension was homogenized for 10 minutes using a Ross laboratory homogenizer followed by one pass through the Dyno-Mill as in Example 2. The homogenization step facilitated the even pumping of the suspension through the Micromill.
