Myth No. 12 (cont'd)

• Literature indicates essentially no differences in calcium levels for both raw and pasteurized cow and goat's milk.
• Lopez et al. JDS 68:1878-1886
• Generally understood that calcium is present in milk at about 1200mg/l.
• Only 34% of the calcium in milk is soluble; 66% of it is present in colloidal form – bound either to phosphate or citrate.
• Perhaps author is referring to a shift in the equilibrium between soluble and colloidal phases which will occur with temperature changes
• Often, temperature-induced changes in the equilibrium are reversible.
• The majority of calcium in milk is already in the colloidal as opposed to soluble phase.
