Binding of Aflatoxin M₁ to Different Protein Fractions in Ovine and Caprine Milk

Distribution of aflatoxin M₁ (AFM₁) between the retentate and permeate fraction of goat and ewe milk is plotted as a function of the AFM₁ concentration in the original milk.

The distribution of aflatoxin M₁ (AFM₁) between the protein fractions separated by ultracentrifugation from ewe milk is given as a function of the AFM₁ concentration in the original milk.

The distribution of aflatoxin M₁ (AFM₁) between the 2 fractions separated by acidic or enzymatic (rennet) curding is given as a function of the AFM₁ concentration in the original milk.

Typical sensor responses for milk samples containing increasing amount of aflatoxin M₁, and for curd, whey, and by-products obtained by enzymatic or acidic curding of ewe and goat milk.

Principal component (PC) analysis score plots for ewe and goat milk products. In both panels, samples are identified as follows: acidic curd (○); rennet curd (•); acidic ricotta (□); rennet ricotta (■); acidic scotta (▾); and rennet scotta (▴). For each datapoint, values identify the aflatoxin M₁ content in the original milk (ng/kg).
