On the other hand, to satisfy the ongoing demand of the worldwide Argan oil market, other more sophisticated Argan oil extracting methods were adopted (read: imposed).
These might be more efficient and less time-consuming than the traditional one in terms of production and Argan oil bottling quantities.
Nonetheless, the chemical extraction tops both the traditional and the mechanical ones!
Anyway, I wouldn´t necessarily call these Argan oil extraction methods “advanced” (especially the 100% mechanical ones!) as the quality and potential of the Argan oil they produce can in no way compete with the traditional one.
Yes I know, the cosmetics industry is promoting the opposite and some invented fallacies to oil their marketing wheels!
The basic processing of most of the methods using mechanical presses consists in powdering the Argan kernels before pressing their dough directly, skipping the mixing-with-water step they judge as superfluous and needless! (semi-mechanical excluded)
The Argan kernels used in this method are often un-roasted to gain more Argan oil, but they loose quality in comparison to the extraction with roasted ones.
The extracting time is much faster: only a couple hours are needed to extract 1 litre of Argan oil using the mechanical method.
