Effects of physical refining process on quality and stability of argan oil (Argania Spinosa (L.) Skeels).

Subquality argan kernels are 30% cheaper than the regular kernels mandatory used to prepare edible argan oil. The use of these argan kernels for the preparation of argan oil intended to be a cosmetic ingredient, after bleaching and deodorization, is therefore particularly economically appealing. The oxidative stability of Argan oil prepared from subquality kernels is unknown.
