Onions: A Versatile Ingredient with Surprising Benefits
Onions are a staple ingredient in many dishes. Comprised of 89% water, 9% carbs, and 1.7% fiber, with small amounts of protein and fat, they also contain quercetin, a flavonoid compound and antioxidant. Quercetin has anti-inflammatory properties, aids the body’s production of vitamin E, and protects against various cancers and cardiovascular issues.
Despite their common use in daily life, not many are aware of these special properties of onions:
1. Repels insects and soothes insect bites
While it may be unpleasant to rub an onion on your skin due to its strong odor, doing so can effectively repel insects. Onions can also alleviate pain and swelling from insect bites.
2. Cleans rusty knives
If you have rusty knives at home, chop an onion and rub it on the blade. Onions contain sulfanilic, which reacts with rust, breaking down its structure and restoring the knife’s shine.
3. Cleans metal surfaces
Mix equal parts onion juice and water, then dip a soft cloth into the mixture and gently rub it on the metal surface. Finally, rinse with warm water, and your metal will be sparkling again.
4. Deodorizes strong odors
Despite its pungent smell, onions can effectively neutralize strong odors in the kitchen. Simply place an onion near the stove while cooking, and say goodbye to lingering grease smells.
5. Removes burnt rice smell
If you accidentally burn your rice, place some sliced onion in the pot while it’s still hot and cover it. The burnt smell will disappear, leaving your rice edible.
6. Prevents mold
Adding two onion stalks to your soy sauce or vinegar will keep them from molding, allowing you to keep them for a more extended period.
7. Cleans copper items
Cut an onion, dip it in salt, and then use it to scrub your copper items. This will effectively clean and shine them.
8. Eliminates paint fumes
For newly painted homes, the paint fumes can be overwhelming. Placing an onion nearby will absorb these fumes, leaving your home smelling fresh.
9. Cleans and shines glass
Cut an onion in half and rub it on your glass surfaces, then wipe with a clean cloth. Your windows and mirrors will be left sparkling clean.
