Detoxification of corn [Aflatoxins]

Corn samples contaminated with aflatoxins were ground by a Wiley Mill, using a 40-mesh sieve to make meal. The toxin level was reduced to less than 20 ppb, as detected by minicolumn tests. Detoxification was done by the separate treatments of 3% hydrogen peroxide, 75% methanol, 5% dimethylamine hydr...

description Corn samples contaminated with aflatoxins were ground by a Wiley Mill, using a 40-mesh sieve to make meal. The toxin level was reduced to less than 20 ppb, as detected by minicolumn tests. Detoxification was done by the separate treatments of 3% hydrogen peroxide, 75% methanol, 5% dimethylamine hydrochloride or 3% perchloric acid. Loss in fresh weight by these treatments was 28, 14, 7 and 7%, respectively. Loss in. proteins and lipids due to the detoxification processes did not exceed 0.5 and 0.6%, respectively, when compared with the fresh weight of corn.
