	<dc:description xml:lang="en-US">To determine the chemical composition (dry matter, crude protein, ash, neutral detergent fiber, acid detergent fiber, cellulose, lignin and hemicellulose), and physical properties (solubility, water adsorption capacity and volume) of three batches of Plukenetia volubilis L. (Sacha inchi) cake, as well as its mineral profile (Ca, P, Mg, K, Na) and secondary metabolites, a simple classification design was applied and differences were analyzed using ANOVA and Duncan test (p&amp;lt;0.05) with the use of INFOSTAT. Results showed significant differences (p&amp;lt;0.05) in NDF (batch three: 25.82 % vs. batches one and two: 28.11-29.90 %), DM, ADF, and cellulose, which did not vary among all batches. There were no differences (p&amp;gt;0.05) in CP, lignin, hemicellulose, nor in the physical properties. Batch three showed a higher content of macrominerals (except phosphorus) compared to batch two, while batch one showed intermediate values: Ca (0.19 %), P (0.79 %), Mg (0.12 %), K (0.24 %) and Na (0.44 %). Saponins and α-amino groups were identified qualitatively, being abundant in all batches. It is concluded that the chemical composition of Sacha inchi cake varies among batches, except for protein, lignin, and physical properties. Batch three stood out for its lower content of NDF and higher mineral concentration, suggesting its potential preference for nutritional applications.</dc:description>
	<dc:description xml:lang="es-ES">Para determinar la composición química (materia seca, proteína bruta, cenizas, fibra detergente neutro, fibra detergente ácido, celulosa, lignina y hemicelulosa) y propiedades físicas (solubilidad, capacidad de adsorción de agua, volumen) de tres lotes de torta de Plukenetia volubilis L. (Sacha inchi), así como su perfil mineral (Ca, P, Mg, K, Na) y metabolitos secundarios se aplicó un diseño de clasificación simple y se analizaron las diferencias mediante ANOVA y prueba de Duncan (p&amp;lt;0.05) con el uso del INFOSTAT. Los resultados mostraron diferencias significativas (p&amp;lt;0.05) en FDN (lote tres: 25.82 % vs. lotes uno y dos: 28.11-29.90 %), MS, FDA y celulosa, que no variaron entre todos los lotes. No hubo diferencias (p&amp;gt;0.05) en PB, lignina, hemicelulosa ni en las propiedades físicas. El lote tres presentó mayor contenido de macrominerales (excepto fósforo) con respecto al lote dos, mientras que el lote uno mostró valores intermedios: Ca (0.19 %), P (0.79 %), Mg (0.12 %), K (0.24 %) y Na (0.44 %). Se identificaron cualitativamente saponinas y grupos α aminos, abundantes en todos los lotes. Se concluye que la composición química de la torta de Sacha inchi varía entre lotes, excepto en proteína, lignina y propiedades físicas. El lote tres se destacó por su menor contenido de FDN y mayor concentración de minerales, lo que sugiere su potencial preferencia para aplicaciones nutricionales.</dc:description>
