Abstract
Antioxidant compositions for protecting food and cosmetic products from oxidation are isolated from olives by grinding olives to obtain ground olive material which then is dried and then the dried material is pressed which provides for recovering and obtaining, from the pressing, a lipid composition separate from a pressed olive cake, the lipid composition containing lipid-soluble and water-soluble antioxidants. Additionally, further treatment of the cake material by combining a medium chain triglyceride, glycol, or a C.sub.2 -C.sub.6 alkyleneglycol with the cake material and then pressing under a pressure of at least 40 bar provides for recovering and obtaining water-soluble antioxidants from the cake material.
