Bitterness, natural antioxidants and quality indices of virgin olive oil from different growing areas

Abstract: The purpose of this investigation was to study different in the bitterness (K225), natural antioxidant (total polyphenol, orthodiphenol, α- tocopherol, chlorophenoll and carotenoid ) andquality indices (free fatty acids, peroxide value, spectrophotometric K232 and K270, organoleptic testes, color, oxidative stability) of virgin olive oil from Kornona;ii verity cultivated in different olive growing areas in Egyptnamely Giza, El-Sharkia, and El-Arish were determined. Phenolic compounds were analyzed by HPLC (high performance liquid chromatography).
