Minerals composition (Ca, Na, Pb and Sn) of Sudanese white soft cheese

Minerals composition (Ca, Na, Pb and Sn) of Sudanese white soft cheese purchased from White Nile state had been investigate, the cheese samples were packed in to 5 different packaging techniques, metal tin (lined with polyethylene bags and non-lined), plastic container (lined with polyethylene and non-lined) and petroleum gallon as a control. The Calcium and Sodium content decreased significantly (P ≤ 0.05) throughout the storage period from 9.5 and 11.13 ppm at the beginning of the storage period to 7.0 and 2.47 ppm at the end of the storage (180 days) respectively, where there were no significant differences between samples kept in lined and non-lined metal tin packages. The significantly higher level of Lead (0.05 ppm) was observed in samples stored in metal gallons sealed by soldering at 60 days storage whereas the significantly (P ≤ 0.05), lowest value 0.026 ppm of Pb content was observed in samples stored in plastic container at 120 days storage. The Tin content in all samples was under the detected level.
