PROCÉDÉ DE PRÉPARATION D'UNE HUILE COMESTIBLE, CARACTÉRISÉE PAR UNE DURÉE DE CONSERVATION PLUS LONGUE, ET HUILE COMESTIBLE POUVANT ÊTRE OBTENUE PAR UN TEL PROCÉDÉ
Method of preparing an edible oil, characterized by an increased shelf-life, and edible oil obtainable by such method is provided. A method of preparing an edible oil, particularly extra virgin olive oil, is described, including the operation of introducing a predetermined number of olives having a polyphenolic content ranging between 1000-3000 mg of polyphenols/kg of olives in a predetermined volume of oil. In a preferred embodiment, the olives are preventively treated with an anti-mould agent, and are dehydrated, preferably by thermal treatment in an oven at a temperature ranging between 80° C. and 160° C., so as to achieve the elimination of a water amount ranging between 1% and 30%, preferably between 7% and 15%, more preferably of about 10%. The method of the invention allows obtaining an edible oil, particularly extra virgin olive oil, having an increased polyphenolic content, thereby an increased shelf-life, while maintaining the organoleptic characteristics unaltered.
