odorization
Infusing with fragrance
Odorization is the process of adding a distinctive smell to something naturally odorless, especially for safety purposes.
Natural gas is odorless, so utility companies add a sulfur compound that smells like rotten eggs, allowing people to detect leaks: Federal regulations require odorization of all gas pipelines serving residential areas.
