Corn	0.04 ± 0.02	9.46 ± 0.56	0.12 ± 0.01
Wheat	0.03 ± 0.00	14.87 ± 5.11	0.11 ± 0.05
Corn endosperm	0.41 ± 0.11	5.49 ± 1.54	0.17 ± 0.04
Corn germ	6.82 ± 1.14	33.03 ± 3.49	48.21 ± 7.29

Means within rows followed by the same letter are not significantly different at .
Mean aflatoxin B₁ is expressed in milligrams per kilogram ().
An average of 10% corn oil was added to defatted substrates.
