“…Feeding studies on ammoniated cottonseed meals (Vohra et al, 1975;Waldroup et al, 1976) indicate that ammoniated cottonseed meals can safely be fed to laying hens and broilers. The meal fed these birds was ammoniated under the harshest conditions of heat and pressure (115 °C, 45-50 psig).…”

Cultured and spiked peanut and cottonseed meals, high in aflatoxin, were ammoniated under laboratory conditions paralleling those employed for the model ammoniation of pure aflatoxin Bb as well as under conditions used in commercial detoxification with ammonia. In the model reaction, 10% aflatoxin B: remained after ammoniation, and 10% was converted to aflatoxin Dv In all ammoniation studies conducted on spiked and cultured peanut and cottonseed meals, an average of 0.36% aflatoxin B: was converted to aflatoxin Db and an average of 0.37% of the Bx remained unreacted.

“…Only the treatment with volatile bases such as methylamine and ammonia has reached some practical importance in animal nutrition ; Brekke et al, 1978Brekke et al, , 1979Koltun et al, 1974). Acute toxicity of the treated products appear to be greatly diminished by these procedures (Boulton et al, 1979;Friot et al, 1975; Hughes et al, 1979; Manabe et al, 1977;McKinney et al, 1973;Southern and Clawson, 1980; ; Waldroup et al, 1976).…”

3H]Aflatoxin B1 (AF ' B,) was ammoniated at 100 OC and the isolated aflatoxin D1 (AFD,) characterized by 'H NMR and mass spectrometry. AFDl was found to be 130-fold less mutagenic than AFB, in the Ames test. In vivo covalent binding to rat liver DNA expressed in the units of a covalent binding index (CBI, a quantitative indicator for genotoxicity) of [14C]AFDl was below the detection limit of 71 and at least 280-times lower than for AFB1, although AFD, still has the 8,9a double bond. After ammoniation of [14C]AFB1-spiked corn grits for 34 days (18.8% H20/2.02% NH3, 25 "C), 14C distribution and CBI were measured: 7% of the radioactivity was CH2C12 extractable but 14% was extractable when acidified prior to extraction. The H 2 0 phase contained 42% 14C with a CBI of 1000 but only 31% 14C with a CBI of below the detection limit of 145 when acidified prior to extraction. The extracted corn had still a radioactivity of 33% (38% respectively) with a CBI of <126. More than 85% of the H20 fraction pass a dialpis membrane with an exclusion limit of 14 OOO dalt~ns. The results indicate that ammoniation reduces the genotoxicity of AFB,-containing corn at least 20 times. Besides unreacted AFBl the aqueous phase contained about 7% of a still toxic AFBl hydrolysis product, which can rebuild AFBl after acidification.Numerous attempts have been made to detoxify by chemical means natural goods contaminated with aflatoxins (Codifer et al.
