ABSTRACT:
The present invention relates to processes for the treatment of liquors derived from oil-bearing fruit, for example from oil palm fruit, and to products therefrom. Typically a process involves removal of undissolved solids, oleaginous parts, colloids and higher weight molecules from the vegetation liquor to give an aqueous fraction containing phytochemicals, for example, flavonoids, phenolic acids and hydroxy acids. Subsequently, pH adjustment and solvent extraction upon said aqueous fraction realise an extract rich in hydroxy acids or phenolic acids or flavonoids or any combination thereof Applications of the substances subject of this invention are to be found in drinks, edible products, tonics, health supplements, antioxidant additives, cosmetics, soaps, shampoos, detergents, drugs or medicinal products.
