The enzymes are released when cells are broken or crushed; using a sharp knife slices through the onion rather than crushing and thus, fewer enzymes are released. Regardless of whether you employ different tactics too, use a sharp knife in every onion-cutting situation. It'll go that much quicker! This reduces the amount of the acid enzyme released into the air and has zero effect on taste. This was found to be the most effective way to reduce tears by the television program Food Detectives. The fridge can do it, too; just make sure not to keep them next to apples or potatoes, or leave them in there for too long (20 minutes should do it) -- they can cause odors if you do. Whistling makes a significant airflow, specifically away from your face, which keeps the onion mist away from your eyes. Just pick a catchy tune that you won't want to stop whistling and you can cut as many onions as you need. Many people report that chewing, especially bread, helps avoid tears when cutting onions. Chew very slowly, letting the bread hang out of your mouth a little. Your mouth will water, which will be a little uncomfortable, but your eyes won't! Others say to chew gum. When an onion is cut, a chemical is released into the air. It irritates the lachrymal glands, causing them to excrete tears. Chewing gum while cutting onions prevents tears by forcing you to breathe through your mouth.Chewing gum before, during or after cutting onions promotes production of saliva. Saliva absorbs the vapors emitted by cut onions, preventing them from condensing on the eye and causing tears. It is best to start chewing gum before starting to cut onions, and to remember to breathe through the mouth while cutting the onion.
