Fecha de publicación: 31/10/2001 Fuente: WIPO "olive table" For at least one day olive fruits are soaked in vegetable oil, preferably in olive oil, with the effect that polyphenols diffuse into the surrounding oil. The raise of polyphenols in this oil is at least 1 0 ppm. The migrating polyphenols typically are fat soluble polyphenols. Treated oils show an increased stability to oxidation. Their flavour has improved and often receives a higher appreciation than the flavour of the starting oil.
