Do beans test positive for diphenylamine?

Diphenylamine is a chemical that is used as an antioxidant for rubber and as an intermediate in the production of other chemicals. As a result, it can be found in some foods such as beans. When tested for diphenylamine, beans may produce a positive result due to the presence of this chemical. However, the concentration of diphenylamine found in beans is typically too low to pose a health risk.
