Fatty acids pattern of olive oil under organic farming.

Abstract

Organic farming is considered as a mitigation strat egy to face adverse effect of climate change and Consumers’ increasing their need for safe and quali ty food has motivated this research study. The oliv e oil of the Roman olive trees (Landrace) Olea Europea belong to the Oleaceae family growing under organic farming (in the transition period) conditions in Jordan Ajl un area was extracted by traditional method; warming water to the about 60°C and grounded the seeds make as paste then pour in the warmed water then take the oil layer floated at the surface. The oil was analyzed for fa tty acids pattern and compared with Romans trees ol ive oil grown at Burma Agriculture Station which has organic Certificate according to the Japanese Agriculture Standard (JAS) since 2007. The separation patterns of fatty acids were done by Gas Chromatography (GC). Results showed high levels of unsaturated fatty aci ds, particularly oleic acid (up to 67.49%), linolei c acid (13.31%) and linolenic acid (0.74%) in the oil of R omans trees growing in Ajlun area, while the organi c olive oil from the Romans olive trees growing at Burma Station showed 68.88% of oleic acid, 11.73% of linole ic acid and 0.67% of Linolenic acid. The analysis also showed that the palmatic saturated fatty acid was 12.54% at Burma Station compared to 11.82% in Ajlun area. The medicinal value of unsaturated fatty acids play great role for reducing cholesterol rate that was found i n high level of Romans olive trees (landrace).
