Lowering of ochratoxin A level in milk by yoghurt bacteria and bifidobacteria.

A decrease in the content of ochratoxin A (OA) was observed in milk samples fermented by yoghurt bacteria and bifidobacteria. OA was added to the milk before fermentation at a rate of 0.05-1.5 mg/L. No residues of OA were found in samples containing 0.05 and 0.1 mg/L of OA, fermented by S. Salivarius subsp. thermophilus, L. delbrueckii subsp. bulgaricus and B. bifidum. Yoghurt bacteria (S. salivarius subsp. thermophilus and L. delbrueckii subsp. bulgaricus) were the most effective since no residues were detected even in fermented samples containing originally 0.5 mg/L OA.

Decrease of aflatoxin B1 in yoghurt and acidified milks.

Fermentation of yoghurt and acidified milks containing aflatoxin B1 (AB1) were studied. AB1 added to milk before fermentation at concentrations of 600, 1000 and 1400 micrograms/kg was reduced in yoghurts (pH 4.0) by 97, 91 and 90%, respectively. Coagulation time was approximately the same as in the controls. Streptococci had longer chains than those in the controls. The main decrease of AB1 occurred during the milk fermentation. A decrease of AB1 (conc. 1000 micrograms/kg) in milks acidified with citric, lactic and acetic acids (pH 4.0) was 90, 84 and 73%, respectively.
