In daily life, the pecans that people buy home are inevitably mixed with a few imperfect individuals. Their appearance appears dark brown or even black.
For this small number of pecans, there must be people who don't know what to do, and it is inevitable that they will be a little entangled: they want to eat them, but they are worried about what if they have gone bad and carry Aspergillus flavus or other toxinsI want to throw them away, but I see that the meat is white and not bad, and if I misjudge, won't it be wasted?
Speaking of which, I can responsibly tell you that although the kernels of some pecans are "not perfect", it does not mean that they are inedible.
As long as the flesh of the pecans is white, or slightly yellowish, such as ivory, as long as you can be sure that it looks moldy and does not smell bad. Well, it means that they do not breed fungi, and they do not carry aflatoxin. Therefore, such pecan nuts are completely edible.
At this time, some people will definitely ask, "Since it is a pecan that has not deteriorated, how can the surface color turn brown or black?"”
The reason is that pecans have such a characteristic that if they are exposed to air for a long time, the outer color of the kernel will be deepened by the oxidation of the air, and it will become brown or black.
Of course, not all pecans that change color are safe and non-toxic, so be careful to distinguish them.
The first situation: some of the preemptively ripe pecans are in a dry environment, exposed to the air for a long time, and are simply oxidized by the air, but they are not attacked by fungi, so they are safe and non-toxic.
The second situation: after harvesting, improper storage, in a humid environment, as a result, not only is the appearance of the appearance deepened by air oxidation, but at the same time, the mold invades, so that the appearance of the appearance of a fluffy substance, and the meat is not white, but obviously dark yellow, and the color quality is not pure. Such pecans are likely to contain harmful substances such as aflatoxin and cannot be eaten.
Conclusions】 Safe and healthy, toxic pecans without aflatoxin have the following three characteristics
1.There is no mildew on the outside;
2.The flesh is white or ivory;
3.Smells no musty.
