To establish a method for the detection of sesame oil, three color reactions, Villavecchia, Baudouim and Soltsien method, responsible for the coloration of sesamol were collaboratively examined.
These three reactions have long been used as methods for the detection of sesame oil, but the sensitivity and color stability of each of these reactions are studied for the first time in the present research.
The Villavecchia method, using hydrochloric acid and furfural as color reagents, was found to be the best among three methods with respect to the sensitivity and stability of coloration.The detection limits for refined and unrefined sesame oil were 1% and 0.5% respectively.
