Onions, as a common and popular ingredient, not only add a unique taste and flavor to dishes, but also have many nutritional benefits.
When buying onions, we need to pay attention to some details, don't be greedy for cheap, and buy high-quality onions reasonably.
Here are three types of onions that should not be bought:
1.Soft onions.
When we touch an onion, if it feels soft and has no firmness, then it is likely that this onion has rotted.
Normal fresh onions should be hard and hard.
Therefore, when choosing an onion, first touch it with your hands to see if it is soft or hard.
If it's soft, never buy it.
2.Onions with wounds and injuries on the surface should also not be purchased.
If there are visible scars or scars on the surface of the onion, then at least the outer layers of the onion are inedible.
Onions that begin to rot on the inside can produce harmful bacteria that can cause food poisoning.
In addition, buying too many onions with wounds or injuries can also lead to waste.
3.Onions with a strange smell are also not suitable for purchase.
A normal onion should have a spicy taste, and if it smells rotten, it must be broken inside.
If you have already purchased an off-flavored onion, you should immediately refrigerate it and consume it as soon as possible.
For your next purchase, you should choose fresh, fresh-smelling onions.
Choosing the right onion is not only about the freshness of the ingredients, but also about our health.
Therefore, it is recommended that you pay attention to the above three points when buying onions, and avoid buying onions that are soft, wounded or damaged, and have a strange smell.
