Sesame Oil is identified by which test?

• A. Serger test
• B. Halphen test
• C. Baudoin test
• D. Saponification cloud test

Answer: (C)

Baudouin test hinges on sesame oil containing distinctive phenolic lignans such as sesamol and sesamolin. When these compounds react with the Baudouin reagent, they form a colored complex, giving a positive result that is characteristic of sesame oil. Other common edible oils lack these constituents in meaningful amounts, so they don’t produce the same color change. This makes the Baudouin test a useful quick check to identify sesame oil and detect adulteration with other oils.
