Abstract
Sweetened condensed milks contain all the constituents of milk in small bulk with the added advantage of prolonged keeping qualities. However, the sugar content is not a replacement for shortage in sanitary measures adopted during manufacturing and handling of the product. Additionally, the presence of heavy metals constitutes another hazard related to such product.
Since the data of heavy metals in canned sweetened condensed milks is scanty, the present study focused on quantification of the levels of some heavy metals (Pb, Al, Cd, Sn) in commercial canned sweetened condensed milk products sold in Egypt. Furthermore, the levels of aforementioned heavy metals in commercial canned sweetened condensed milk products were estimated during storage period.
Regarding lead, the statistical analysis indicated that the Pb concentration in examined condensed milk samples was ranged from 0.665 to 0.735 ppm with a mean value of 0.7004 ± 0.0174 ppm. Additionally, 15 (100%) of sweetened condensed milk samples were contaminated with Pb above the recommended permissible limit (0.02 ppm). The obtained results lied above the permissible limit recommended by Egyptian Standards (2010) .
The Cd concentration in examined condensed milk samples ranged from 0.192 to 0.231 ppm with a mean value of 0.2120 ± 0.0099 ppm. The obtained results lied above the permissible limit recommended by Egyptian Standard (1993) and Egyptian standard (2001). On the other hand, 15 (100%) of sweetened condensed milk.
