When peeling onions, many people experience the unpleasant side effect of tears streaming down their face. This happens because onions contain a compound called syn-propanethial-S-oxide, which is released when the onion is cut or peeled. This compound irritates the eyes, leading to the production of tears as a protective mechanism. However, there are a few tips and tricks that can help prevent this reaction and keep you from crying while peeling onions. One popular method is to chill the onion in the refrigerator before cutting it. This can help reduce the amount of syn-propanethial-S-oxide released, making it less likely to irritate your eyes. Another trick is to cut the onion under running water or in a bowl of water. The water can help neutralize the compounds released by the onion, reducing the irritation to your eyes. Some people also recommend wearing goggles or sunglasses while cutting onions to protect your eyes from the irritants. Additionally, cutting the onion quickly and using a sharp knife can help minimize the amount of time the irritants have to affect your eyes. Some people also suggest lighting a candle near the cutting board, as the flame can help draw the irritants away from your eyes. Overall, there are several methods you can try to prevent crying while peeling onions. Experiment with different techniques to see which works best for you. And remember, if all else fails, you can always try wearing a pair of onion goggles to keep your eyes safe from irritation.
