Abstract
The invention relates to a method for using the natural biophenols, tyrosol and hydroxytyrosol, contained in the industrial by-products that result from the crushing and processing of olives, whether from three-phase or two-phase presses, and the husks and cakes thereof. The method produces a mixture of the two biophenols with a purity of more than 90% and yields of between 0.1 and 1.5% depending on the product and the processed raw material. The invention essentially comprises the selective extraction and fractionation of the resulting mixtures using solvents.
