Understanding Why Onion Smell Lingers

Onion smell is a common problem when cutting onions on your chopping board. Even after washing, the pungent odor may linger on the surface. Understanding why this happens helps to find a solution. The science behind onion smell on cutting boards involves chemicals called amino acid sulfoxides.

When onions are cut, they release an enzyme that converts these compounds to a gas called syn-propanethial-s-oxide. This gas easily penetrates porous materials like wood, which results in the persistent onion smell. While washing the board with hot water and soap can reduce the odor, it’s not always enough.

Alternative cleaning methods such as vinegar or lemon juice, or using plastic cutting boards that can be easily washed, may help to eliminate the smell.
