Abstract

The effect of some milk processes on the distribution of  Fe, Zn, Cd and Pb elements in the resultant products had been investigated. The levels of these elements in raw milk and the obtained products were estimated in ppm. The distribution in respect of these  elements during the separation of  buffalo's raw whole milk  into cream and skim milk were 9.88 and 90.12% for Fe, 7.37 and 92.38%  for  Zn, 5.88 and 94.10%  for Cd and 6.99 and 93.01% for Pb, respectively. The churning process of the above cream into butter and butter milk showed reducing the values of  these  elements in the resultant butter. It contained 27.10, 16.31, 30.80 and 15.00 % of the cream initial content of Fe, Zn, Cd and Pb, respectively. The major values of the foregoing elements were remainder in butter milk with percentages  of  72.89, 83.63, 91.70 and 85.00% of Fe, Zn, Cd and Pb, respectively. The percentage levels of  Fe, Zn, Cd and Pb in the acid curds obtained after direct acidification of the forgoing skim milk as compared with the initial levels were 69.89, 36.11, 60.36 and 78.61%,  respectively. The drainage whey contained 63.89, 30.20, 64.94 and 58.75 % of these elements in the same respect.
