Abstract

Cow milk, carabao milk, and goat milk were analyzed for Ca and Mg by the EDTA titration method using calcein as indicator and by the (AOAC)) ashing method. The effect of pre-treatment (deproteination with TCA) on the EDTA titration was also studied. The results showed that there is no significant difference between the two methods. The extra step of deproteination is not necessary an EDTA titration. The EDTA method, then, which is equally reliable and less tine consuming than the AOAC method, may be adopted for the analysis of Ca and Mg in cow, carabao and goat milk.
