Argan oil is extracted from the kernels of argan fruits that have been sun-dried for either a few days or up to several weeks. The influence of the fruit drying time on the quantity, quality, and preservation of solvent-extracted argan oil was compared with press-extracted argan oil. Quantitatively, the time necessary for efficient fruit peeling and the amount of extracted oil were determined with regard to the fruit drying time (0 to 28 days). Argan oil quality was studied using, as markers, moisture content, specific extinction, acid index, peroxide index, fatty acid composition, and Rancimat oxidative stability. Oil from fresh fruit presents a high moisture content, high acidity and peroxide values, and short shelf life. Ten to fourteen days of sun-drying is optimum to obtain high quality argan oil.
