    • Abstract:
      Seeds from Cichorium intybus L harvested at Olavarría (Buenos Aires, Argentine) were defatted with petroleum ether (60°-80°) and the raw oil obtained with a yield of 13.3% dry basis. The crude oil was examined in their physicochemical characteristics had refractive index of 1.4576 (at 25°), iodine value of 124.3, saponification index of 191,4, unsaponifiable matter of 5.3 % and free fatty acid content of 6.0 (mg KOH/g). Gas chromatographic analysis of the oil revealed high levels of linoleic acid (59.8%), nearly 21% of saturated acids. The residual seed meal contained 16.9% of crude protein, with a low value of available lysine (1.37g/16 g N). Total and phytic acid phosphorous, calcium, ash, crude fiber, sugar, polysaccharides (non presence of starch) and residual lipids contents are reported. ; Semillas de Cichorium intybus L (Achicoria) cosechadas en Olavarría (prov. de Buenos Aires, Argentina) se agotaron con éter de petróleo (60°-80°), obteniendo el aceite crudo con un rendimiento del 13,3% (base seca). El aceite crudo se examinó en sus características fisicoquímicas (índice de refracción: 1.4576 (a 25°), índice de iodo: 124.3, índice de saponificación: 191.4, insaponificable: 5.3%, índice de acidez: 6.0 (mgKOH/g) y composición acídica. El análisis por cromatografía gaseosa de los esteres metílicos reveló un alto porcentaje de ácido linoleico (59,8%), alrededor de un 21% de ácidos saturados. La harina residual de extracción presentó un 16.9% b.s. de proteína cruda, con un bajo contenido en lisina disponible de 1,37 g/16 g N. Se informan valores de fósforo total y de ácido fítico, cenizas, calcio, fibra cruda, hidratos de carbono y lípidos residuales.
