| Abstract | The sacha inchi oil (Plukenetia volubilis L.), seed originally from Peru, recently grown in equatorial lands, possesses omega-3, omega-6, omega-9 at levels 51,94%, 34,37% and 7,97%. Sacha inchi oil was characterized and compared to canola oil (Brassica napus and B. rapa), an oily seed also planted recently in Ecuador containing omega-3, omega-6, and omega-9 at levels of 12,76%, 17,26% y 63,42%. It was determined which is the best method of oil extraction in these seeds, physicochemical analysis was carried out for the extracted oil and its nutritional composition was established through a fatty acids profile. Three methods of oil extraction were evaluated: mechanical digestion, organic solvent extraction and cold pressing. The utilized experimental design was split plots with six treatments and five variables: acidity percentage, peroxide index, output percentage, omega-3 and omega-9 content. The obtained data from the solution variables were analyzed through ANOVA, tukey test and a student t test. Of all the extraction methods, mechanical digestion and cold pressing provided favorable statistic difference in front of the specification and references. However, from the quality point of view, the best method of oil extraction in both seeds is cold pressing accomplishing the national and international established standards. |
