Chemical composition and detection of Aflatoxin M1 in camels and cows milk in Sudan

ABSTRACT

A hundred samples of milk from camels and cows were analysed for chemical composition and M₁ contamination. The results indicated that camel milk from traditional nomadic systems revealed significantly (P$\le$0.05) higher values for protein, fat, lactose, solids-not-fat and density than that obtained from camel and cows kept in semi-intensive systems. Aflatoxin (AF) M₁ was found in 33% of the milk samples with the highest occurrence (82.4%) in cow milk (35.3% ranged between 0.05 and 0.1 µ/kg and 47.1% ranged between 0.1 and 0.15 µ/kg) compared to milk samples from camel in semi-intensive systems (15.6% ranged between 0.05 and 0.1 µg/kg). All samples of milk from traditional nomadic systems revealed the absence of AFM₁. These results revealed increasing of AF with increased fat content in milk, a decrease with decreasing other milk components, while the density of milk showed no relation.
