Resumo(s)
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.
