How to make original argan oil without adulteration

Abstract

Argan oil is widely known as an edible, cosmetic, and pharmacologically active oil. It is also particularly expensive. Therefore argan oil adulteration with low price vegetable oils is frequent, making accurate, easy to use, and fast techniques to detect argan oil adulteration necessary. In this review, we present the advantages and disadvantages of a range of methods developed to detect argan oil adulteration. Though chromatography or infrared spectroscopy present the advantage of being efficient, easy to use and accurate, these techniques are time-consuming, expensive, and require somehow complexe sample preparation. At the present time, fluorescence spectroscopy appears to be the most efficient technique.
