The answer is that onions are moldy and inedible. Never mind onions, even other vegetables and fruits will be thrown away once they are moldy. Because once the food is moldy, microbial fungi will quickly spread into the vegetables. Although our naked eyes can't find moldy substances in time, it doesn't mean that the rot doesn't go deep into the cabbage. Moreover, after the appearance of the onion is moldy, the rotten part will produce mycotoxin, which will be poisoned after eating, so the onion can't be eaten when it is moldy and cut.

Onions are nutritious, but they should be purchased reasonably.

Onion is an imported vegetable. Because of its comprehensive nutritional value, it is known as the "vegetable queen", which is worthy of its name. Because there are more nutrients in onions than you can count, and the daily consumption rate is high, you should pay attention to the following points before buying onions:

1. Choose dried onions.

Because the onion with moldy skin can't be eaten, it should be noted that the drier the skin, the tighter the package, which means the higher the freshness. The layered, dry-skinned onions have a complete texture after being cut, and orange and purple onions are also the freshest.

2. Onions should be kept reasonably.

Usually buy too many onions, you can't eat them all at once, so you should learn to store them reasonably. Onions should be stored in a dry and ventilated place at home, avoiding damp and hot places in the kitchen, otherwise it will easily lead to mildew, and be careful not to put them in the refrigerator, because there is too much water in the refrigerator, which will also lead to onion rot without ventilation.

Fresh ingredients and perfect cooking can make our family enjoy delicious onion dishes. In fact, it's not just onions, all the ingredients in our family should be stored reasonably. Because moldy and rotten food must not be eaten, the bacteria produced by rotten food can easily lead to food poisoning. I would like to remind everyone that if the ingredients are found to be spoiled, they should be cleaned up and thrown away in time, and never take risks.
