Abstract
Fragrant sesame oil is very popular among consumers for its unique and rich flavor and pure color. At present, the phenomenon of fragrant sesame oil adulteration increasingly grows serious, and it is urgent to establish a rapid detection method which can be applied to the on-site determination of fragant sesame oil. Three methods are compared in this paper, including the color reaction of sulfuric acid, sucrose hydrochloric acid and furfural. The first method does not require any special reagents and equipment, and fragrant sesame oil content can be determined quickly and accurately. However, the sensitivity is not high. Because of the color instability or improper operation, the color reaction is not accurate in the second method. The last method is highly operable and has a high accuracy. And its color reaction is quite accurate, but not precise enough. Comparing the three methods, the most suitable one can be selected according to the market demand.关键词
