soybeans were stored overnight at room temperature (25 C) to
evaporate the solvent. Analysis of the contaminated samples was
carried out before treatments for AFs degradation to calculate the
initial concentration of AFs in the samples.
2.4. Effect of organic acids during soaking process on the reduction of
AFs
Each sample contaminated by AFs was submerged in the same
volume of solutions such as distilled water (control), 1.0 N citric
acid, 1.0 N lactic acid, 1.0 N succinic acid, and 1.0 N tartaric acid
for 6 h and 18 h at room temperature (3.0 mL per g of contaminated
soybean). The steep liquor was removed, and then the treated
samples were washed with running water three times to neutralize
them. The washed samples were then dried at room temperature
(25 C) in a fume hood for 72 h.
