Abstract

RUIZ, Candy; DIAZ, Camilo; ANAYA, José  and  ROJAS, Rosario. Proximate analysis, antinutrients, fatty acids and amino acids profiles of seeds and cakes from 2 species of sacha inchi: Plukenetia volubilis and Plukenetia huayllabambana. Rev. Soc. Quím. Perú [online]. 2013, vol.79, n.1, pp.29-36. ISSN 1810-634X.

We determined the proximate composition, amino acid profile, fatty acid profile and antinutrients contents (saponins and tannins) of seed and cakes (residues after oil extraction) of Plukenetia huayllabambana and Plukenetia volubilis. The seeds of P. huayllabambana, from the province of Mendoza Rodríguez, has higher oil content (54.3 versus 49.0%), while those from the province of San Martín (P. volubilis) showed higher protein content (29.6 versus 24.5%). Furthermore, protein content of P. volubilis´cake is greater than the one of P. huayllabambana (59 and 46%, respectively). The essential amino acid content of the seeds of both Plukenetia species is adequate, as recommended by the FAO/WHO, except for the amino acids lysine and leucine. In cakes, as well as seeds, the concentration of linoleic acid (omega-6) was larger in P. volubilis, while linolenic acid (omega-3) was found in greater proportion in P. huayllabambana.

Keywords : Aminoacids; fatty acids; Inka peanut; Plukenetia huayllabambana; Plukenetia volubilis.
