Acid
Pickling is often done with vinegar, which is diluted acetic acid, making whatever is pickled acidic.
I would assume pickled onions. Perhaps pickled in acetic acid. Vinegar.
Sulphuric acid or H2SO4
I don't know what critic acid is.
Sulfenic acids don't exist in raw onions; they appear as degradation products of alliin only after cutting onions.
No. There is no research that says that cutting onions is good for your eyes. Cutting onions releases thiopropanol sulfoxide which, when it hits your eyes, creates a small amount of sulfuric acid. This is why your eyes burn and you cry when you cut onions.
Onions have a high acid content and this makes them strong in flavor and makes you cry when cutting them.
Heating acids degrades them which reduces the amount of acid content when it breaks the acids down. So by cooking onions you are in essence reducing the acidic content, but you are also concentrating other flavors. On a side note, if you are referring to reducing the eye irritation when cutting or bruising onions then that is a little different. Onions contain sulfuric compounds that produce sulfuric acid when they waft in the air and make contact with the water in your eye. The sulfuric acid burns your eye and your tear ducts release tears to try and wash it out or dilute it enough to stop the burning sensation.
it is true that if you chew gum while cutting onions you will not cry
Acid
Plain Silverskin Onions: silverskin onions, water, spirit vinegar, acetic acid, flavorings, preservatives
When You Cut Onions The Invisible Oil You Can't See Goes In Your Eyes And It Burns Your Eyes Alot And That's Why It Makes You Cry But You Don't Really Crie Like Sobbing,Your Eyes Are Just Burned And It Waters.
The onions arent an alkali or an acid,but the thing they're soaked in- vinegar makes them pickled. Vinegar is an acid.
