composition of tocopherols in sesame seed oil: an indicative of adulteration
Article Quality & Performance Metrics
Abstract
The objective of this research was to verify how the composition of tocopherols can help to reveal adulteration in samples of sesame seed oils commercialized in Brazil. Five samples have been analyzed. One sample presented the composition of fatty acids, tocopherols and desmethylsterols of authentic sesame oil. Another one presented only non complying parameters. Three other samples showed the fatty acid composition of pure sesame oil, but the tocopherol and desmethylsterol profiles did not comply with those for sesame seed oil. The results indicate that samples could be adulterated by other vegetable oils like soybean, lauric and corn oils.
Este trabajo examina la importancia de los tocoferoles en la detección de la adulteración del aceite de sésamo comercializado en Brasil. Se analizaron cinco muestras a las que se le determinaron su composición en ácidos grasos, esteroles y tocoferoles. Una de las muestras se reveló puro aceite de semilla de sésamo; en otra, todos los parámetros estaban en desacuerdo. En las demás, el perfil de ácidos grasos caracterizaba el aceite de sésamo, sin embargo los tocoferoles y esteroles permanecieron en desacuerdo. Los resultados indican adulteración con otros aceites vegetales como soja, aceites láuricos y maíz.
