In the present paper a chemical and sensory evaluation of oils produce
d by four of the most common cultivars of Istria (Leccino, Buga, Carbo
nera and Bianchera) has been performed. Besides the most commonly used
chemical analyses (acidity, peroxide value, U.V. absorption, fatty ac
ids, sterol and aliphatic alcohol content), the oil quality was also e
valuated by panel test supported by the determination of phenolic and
flavour compounds.
