ABSTRACT
The acidic composition of extracted 1995-1996 olive oils have been studied according to the main varietes existing in Tunisia. Our results show that different oils have the same acidic composition. However, oils extracted from northern varietes are more rich in oleic acids [mean 66,72% VS, 52,43% in the south], but less rich in palmitic acid [11,93% VS 19,85% in the south]. The ratio saturated fatty acids/insaturated fatty acids increases from north to south [0,175 VS 0,291] leading to blood oils in the latter region

Triglycerides composition of Tunisien olive oils from 1995-1996 [oleicol campaign] was studied according their main varietes Our results show that triglycerides of the studied olive oil had portion numbers [equivalent carbon numbers = ECN] ranging from 42 to 50. In addition, triglyceride composition was closely clinked to the acidic composition, trilinolein [LLL] was higher than the european norm [less than 0.5%]. The difference between theoritical and practical ECN42 did not exceed 0.3%. These results are in agreement with the C.O.l. norms
