A process for extraction of phytochemicals from vegetation liquor derived from oil-bearing fruit including: contacting the vegetation liquor with a material that preferentially adsorbs or absorbs oleaginous parts filtering the vegetation liquor to yield an oleaginous retentate and a colloidal aqueous solution and filtering the colloidal aqueous solution obtained from the vegetation liquor, with a hollow fibre filter, wherein the hollow fibre filter is configured to remove molecules above 10000 Daltons in molecular weight and allows molecules 10000 Daltons or less to pass through as aqueous permeate wherein the aqueous permeate comprises phytochemical.
