The effect of ultrafiltration‐diafiltration (UF‐DF) on removal of aflatoxin M 1 (AFM 1 ) from raw whole, homogenized and acidified milk was studied. Milk was artificially augmented with concentrations of AFM 1 varying from 0.5 to 3.5 μg/L. The removal of AFM 1 was influenced (p<0.05) by the initial concentration and the homogenization process. Homogenization and acidification decreased the removal of AFM, from milk. The UF‐DF process did not result in concentrates within permissible residual levels at any concentration studied. However, reconstituted retentates had residual levels of AFM 1 < 0.5 μg/L resulting from milk originally containing up to 2 μg/L.
