Abstract

The research study presented in this paper, the first of its kind in Albania, characterizes the fatty acid profile and total phenolic content of some olive varieties, namely, Boçi, Ulli i Kuq, Ulli i bardhe Lezha, Sterbjak and Micka all harvested during crop year 2010-2011. Annual production capacity of the country is 56 000 tons of olive fruits and 7000 tons of olive oil. Fatty acid (FA) profiles to the studied olive cultivars exhibit a great variation in oleic acid, from 66.32 ± 0.14 % (Ulli i Kuq) to 75.13 ± 0.31 % (Sterbjak), values which are within the normal range for such FA. The content of linoleic acid varies from 7.23 ± 0.04 % (Sterbjak) to whereas the content of linolenic acid varies from 0.45 ± 0.01 % (Ulli i Kuq) to 0.96 ± 0.01 % (Sterbjak). All studied olive varieties revealed moderate levels of palmitic acid, which varied between 10.76 ± 0.05 % (Sterbjak) and 13.05 ± 0.02 % (Boçi). From a nutritional point of view, it is worth noticing that the Sterbjak variety has an n-6/n-3 ratio of 7.68, while the Ulli i bardhe Lezha goes to 10.20. The Total Phenolic Content for the studied olive cultivars varied from 63.02 ± 5.63 GA mg/kg olive oil (Ulli i kuq) to 322.05 ± 3.97 GA mg/kg olive oil Ulli i bardhe Lezha such variation reflect differentness among studied olive varieties.
