If corn does not look black on the outside, can it still be contaminated with mycotoxins?
If normal corn does not look very dark to the senses, is it more or less always contaminated with some level of mycotoxins?
How can mild mycotoxin contamination be detected?
Is there any threshold?
--------------------------------------
It is not easy to see with the naked eye.
--------------------------------------
Mild contamination cannot be seen; even if some moldy corn has been washed and dried, you still cannot tell, though the taste is still acceptable.
Mild contamination is also very hard to avoid, and storage after being put into the silo is also a problem. If stored corn is found to have a problem, it must be dealt with first; how exactly to deal with it depends on each company.
--------------------------------------
--------------------------------------
They are divided into field toxins and storage toxins. There will always be some; it just depends on whether the content is below the limit set by national regulations, or whether it can reach a dose that poisons animals. Experimental studies have shown that low doses of mycotoxins can even promote animal growth.
--------------------------------------
What methods do you all use to test for mycotoxins?
Could you introduce them?
--------------------------------------
Looking forward to an answer.

Mild contamination is very hard to see. In practice, if there are two or more contaminated grains in a hundred grains of rice, it is already contaminated. Your blackening could also be dried corn from Northeast China.
--------------------------------------
Dried corn contains quite a lot of scorched kernels, so the color does not look very bright,
