Summary
Scientists at Cornell University discovered how to cut onions without causing tears. The study found that using a sharp knife and cutting slowly can help reduce the release of tear-inducing chemicals. This research also suggests that keeping knives sharp can prevent the spread of bacteria during food preparation.
Key Facts
- Researchers found tear-inducing chemicals in onions are released due to cell pressure when cutting.
- Sharp knives and slow cutting can minimize chemical release, reducing tears.
- The discovery was published in the journal Proceedings of the National Academies of Science.
- Blunt and fast cutting increases the spread of droplets that contain onion chemicals.
- The study showed droplets can eject at speeds up to 89 miles per hour.
- Sharp knives not only reduce tears but also help prevent the spread of bacteria.
- Onion mist can launch pathogens far, highlighting the importance of sharp knives for safety.
