1. The Role of Sulfur Compounds

 

The main reason why onions cause tears is the presence of sulfur compounds. When you cut an onion, enzymes break down these compounds, releasing a volatile gas called syn-Propanethial-S-oxide. This gas irritates the eyes, leading to tear production. However, different onions contain varying amounts of sulfur compounds, which affects how much they make you cry.

 

2. Which Onions Are More Tear-Inducing?

 

Not all onions are equally potent in causing tears. Here are some common types of onions and their effects:

 

  • Yellow Onions – These contain high levels of sulfur compounds, making them the most likely to cause eye irritation.

 

  • Red Onions – Similar to yellow onions, they also have a strong concentration of sulfur compounds.

 

  • White Onions – These have slightly lower sulfur content and may cause fewer tears.

 

  • Sweet Onions (Vidalia, Walla Walla, etc.) – These have a much lower sulfur concentration, making them less likely to make you cry.

3. How to Reduce Eye Irritation When Cutting Onions

 

If you want to minimize tears while cutting onions, try these tips:

 

  • Chill the onion in the refrigerator for 30 minutes before cutting.

 

  • Use a sharp knife to reduce the amount of cell damage and limit the release of sulfur compounds.

 

  • Cut onions under running water or use a fan to disperse the gas away from your eyes.

 

  • Wear protective eyewear such as goggles to prevent eye irritation.
