How long can the onion be preserved
Onions can be not bad for months.
Onion is more resistant to vegetables, but if it is stored improperly, it will also cause bad, dry shrinkage. The fresh period of onion ripening is the period with the highest nutritional value. In the course of storage, the onion nutrients will gradually decrease, and if the onions have begun to sprout or become soft in some places, they cannot be eaten anymore. Therefore, we must pay attention to the method of onion storage.
1, hanging. In small quantities, the well-dried onion pods can be hung under the eaves or in the back of the greenhouse, as long as ventilation, drying, and rain are absent.
2, billet. Mix the well-dried onion head with fine sand and mud, dry it in a dry and ventilated place, and watch out for rain and moisture.
3. Fresh ready-to-eat onions are best stored in an open container and should be kept away from moisture. Once the onion is cut, even if it is wrapped in plastic wrap and stored in the refrigerator, its nutrients will be quickly lost due to oxidation. Therefore, it is best to eat as much onions as you can, and try to avoid storing after cutting.
Onion cutting without tears
1) As we all know, onions are also old and the smell is heavier, so if you don't want tears when cutting onion, fresh onions are best;
2) The knife should be ground faster. After peeling the onion, it releases a pungent odor. The longer it takes, the heavier the smell. So the faster the knife is, the better it will be, and the shorter the onion release time will be.
3) Appropriate methods, especially when cutting onions with onion, the appropriate cuts can also shorten the onion time;
4) In addition, the salt on the hands of the onion, or the onion in the cold water bubbles can slow the release of the odor.
