Looking sharp objects, the eyes can still stare but when faced with onions, eye once sobbed rapidly. Why eye can not stand with onions?

Onions are one of the many seasonings used in cooking. But, if someone wants to use it must get ready to cry.

In addition to cooking, garlic is also believed to contain chemicals that function as anti-cholesterol, anti-inflammatory, an antioxidant and can also help overcome the blood pressure.

Why slicing or peeling onions make people cry?

When a person is cut or peel the onion then she broke the cells in the onion that combines each layer. One membrane of onion contain enzymes, while others contain sulfur compounds.
When the onion sliced or peeled, the chemical reaction occurs between the enzyme and also sulfur compounds that produce gas volatile (easily evaporated). This gas will react with the surrounding air becomes sulfuric acid.




Because the nerve endings of the eye is very sensitive, then hit the gas when the eyes become irritated and stimulate watering to protect the eyes. Because it would not be surprised if more and more onions are cut, the tears that come out will be more and more also.

But, if the onion has entered into a skillet or frying pan then one would not stop crying or tears.

"This is because during the cooking process, the enzyme that produces these gases will be destroyed or no longer active so it does not make the eyes become irritated," said Dr. Gerry Russell, professor of food biochemistry from the University of California.

To reduce irritation, so not many tears that come out when confronted with the onion, there are several ways you can do are:
  1. Keeping the distance eyes with onions, increasing distance, the gas that irritates the eyes will be fewer and fewer.
  2. Keeping onions stay cool, this is due to cool the onions can reduce the gas that comes out due to enzyme inactivation.
  3. Using the goggles, the goggles will make the eyes are protected, thereby reducing irritation.
  4. Chewing gum, chewing will make someone breathe through the mouth, thereby reducing the gas exposures to the eye.
  5. Try not to be rubbed his eyes because it will make the eye more irritated and trigger more tears came out.
