| Abstract: | The effect of ultrafiltration-diafiltration (UF-DF) on removal of aflatoxin M1 (AFM1) from raw whole, homogenized and acidified milk was studied. Milk was artificially augmented with concentrations of AFM1 varying from 0.5 to 3.5 μg/L. The removal of AFM1 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 AFM1 < 0.5 μg/L resulting from milk originally containing up to 2 μg/L. |
