Etude comparee des acides gras des huiles d'olives Tunisiennes

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
