Abstract

This study was made to apply the extraction method with temperature and vaccum application to internal and external fat of ñandú (Rhea Americana) to obtain a ñandú oil which once refined, has the humidity, acidity, peroxide value, color and fatty acid content similar to the ones required for the international trade of ratities oil. The refine method was the alkali one. The conditions used for the neutralization were NaOH 10% with 0.1% in excess. Then the oil was washed until a soap content lower than 50 ppm because they affect the acidity value. In this way the acidity values obtained were lower than the ones required from the AEA (American Emu Association) for the emu extra refined oil. Supreme 126 earth was used for the whitewash in a concentration of 0.5%. There was found no differences between the internal and the external fat. In the winterization process there were obtained two fractions with different fatty acid contain: the olein fraction was richer in unsaturated fatty acids. The oleic acid content was almost the same in both fractions, while the linoleic acid was higher for the olein fraction. In this study the product was an oil which characteristics and quality parameters are acceptable for the international requeriments for the oils used in cosmetics, and make it easy to trade. Because of this the extraction and refination methods applied are suitable for this use.
