“Olive” Olea europaea (Oleaceae) oil is obtained by mechanical grinding, whipping and centrifugation of the fruit of the olive tree, for the denomination of extra virgin oil it is necessary that the acidity is less than or equal to 0.8% expressed in oleic acid and a score less than or equal to 6.5 points, preserving the original polyphenolic compounds, which confer the great quality of taste and aroma. In this context, the present study aims to determine the stability of the sensory quality of extra virgin olive oil variety Farga and Frantoio with Farga in the period from March to October, according to the unidirectional analysis of variance there is no difference Statistical significance in the chemical results of acidity and peroxide index in the extra virgin olive oil of the Frantoio with Farga variety, unlike the extra virgin olive oil of the Farga variety that presented different values ​​at the beginning and end of the evaluation period. It was determined that there is a significant correlation between the peroxide index and the sensory results, therefore, the authors consider that the extra virgin olive oil of the Frantoio with Farga variety presents greater stability than the extra virgin olive oil of the Farga variety.

Keywords : Farga; Frantoio; Extra virgin olive oil; acidity; peroxide index.
