Abstract
Milk adulteration comes in numerous forms, and it is prohibited due to its determined impact on health. One hundred and fifty cow's raw milk samples were obtained from dairy shops and farmers' houses (75each) in New Valley Governorate, Egypt. The samples were physically and chemically analyzed using an Automatic Milk Analyzer to determine the added water to milk, the density of milk, freezing point, fat content, solid nonfat, total solid and moisture content. Additionally, the samples were tested using general and specific tests for the detection of preservatives and inhibitory substances in addition to the addition of some commercial additives. The obtained results indicate that the samples were adulterated by mixing with water, partial fat removal, addition of inhibitory substances and different preservatives in varying percentages. Dairy shop milk samples showed greater adulteration levels than those of farmers' houses. Overall, it was inferred that the milk marketed in New Valley governorate was processed and handled under inadequate quality control protocols.
