Liquid chromatography/mass spectrometry (LC/MS) profile of AFB₁ degradation. (A) +ESI TIC scan of AFB₁ standard substance; (B) +ESI TIC scan of untreated group; (C) +ESI TIC scan of S. thermophilus fermentation group. Peanut meal was fermented by S. thermophilus for 3 days at 37 °C; (D) +ESI TIC scan of Z. rouxii fermentation group. Peanut meal was fermented by Z. rouxii for 3 days in 28 °C. AFB₁ of all groups was adequately dissolved and extracted by methanol.
