Abstract

The research work was aimed to evaluate the microbiological quality of dried mixes of dairy products highly consumed by the public in Egypt. To verify the quality and safety of these products, 90 random samples of whipped cream; chocolate pudding powder and sauce (all in powder form and main component is milk powder either full or skimmed milk powder and other components differ in each product) were collected from different manufactures. These products examined for total bacterial count (average counts were 8.72x104; 9.29x104 and 1.29x105 cfu/gin examined samples of cream, chocolate pudding and sauce respectively).While, total thermophillic count were detected in examine samples of whipped cream and chocolate and failed to be counted in sauce samples. In addition, the total coliforms counts and total yeasts and molds counts were recorded. Also, the examination of these products for contamination by some pathogenic microorganisms were done and revealed that E. coli O157:H7 and coagulase positive S. aurous could not be isolated from all examined samples. While listeria monocytogenes could be isolated from chocolate pudding in percentage of 26.7 %. The microbial population detected in terms of numbers and types of microorganisms reflect the poor hygienic standard of production which constituting a public health hazard.
