    Evaluación de la preferencia sensorial en consumidores de paté de trucha ahumada elaborado con diferente composición lipídica.
    (Universidad Nacional de Entre Ríos, 2024-08-21) Prario, María Inés; Asiain, Arturo; Waldman, Paula; Cecchi, Federico Alcides; Córdoba, N.; Landolfo, T.
    Siguiendo la metodología de Hualde et.al. (2010), se llevó a cabo un ahumado en caliente de un kilo de trucha arcoíris. Posteriormente, los descartes fueron triturados hasta obtener una consistencia de picadillo base. A partir de allí, se prepararon dos formulaciones de paté ahumado. La primera, denominada Formulación A, contenía 12,3% de manteca, 8,6% de harina de trigo, 18,4% de crema de leche y 18,4% de leche entera y 42,3% de pasta de pescado mientras que la Formulación B, se sustituyó el contenido total de manteca por una combinación de aceite vegetal y harina, manteniendo el resto de los ingredientes en las mismas proporciones que la Formulación A.

    Evaluación del potencial de efluentes de sistemas ras para su utilización como abono orgánico en la horticultura
    (Universidad de Buenos Aires (Facultad de Ciencias Veterinarias), 2024-08) Zanazzi, Aldo Nahuel; Cecchi, Federico Alcides; Tomaselli, Brian; Cuestas, Natalia R.; Mumare, Farid; Callejón di Lena, Antonella; Rodriguez, Yamila E.
    Los objetivos de este trabajo fueron, en primer lugar, determinar la concentración de nutrientes esenciales para las plantas y el contenido de metales pesados de los efluentes tratados, y posteriormente, evaluar su efectividad como abono orgánico en el cultivo de lechuga Lactuca sativa.

    Converting agricultural and fisheries waste into high-value products: Utilization of pea meal and shrimp protein hydrolysate as feed components for Nile Tilapia (Oreochromis niloticus)
    (Iranian Society of Ichthyology, 2025-02-25) Liebana, Clara; Rodriguez, Yamila Eliana; Fernández-Gimenez, Analía Verónica; Cecchi, Federico Alcides; Pereira, Nair de los Ángeles
    This study aims to characterize pea meal and shrimp protein hydrolysate as alternative protein ingredients, replacing soybean meal (SBM) in tilapia feed. The presence of protease inhibitors and the in vitro digestion were evaluated for both raw and extruded pea meals, while the characteristics of shrimp protein hydrolysate were also studied. The nutritional quality of alternative ingredients was assessed to formulate a diet that meets tilapia juveniles’ requirements, and its preliminary effects on growth were evaluated. Extrusion significantly reduced the inhibitory effect of pea meal on tilapia proteases (from 5.4 to 1.9%). In vitro, protein digestion of extruded pea meal (7.8±1.35%) did not differ from the control treatment with fish meal (11.8±1.94%). Additionally, shrimp protein hydrolysate presented 41.6±2.91% of DPPH radical scavenging activity. Tilapia fed a diet including 25% extruded pea meal and 10% shrimp protein hydrolysate, replacing soybean meal, presented comparable growth indicators to those exposed to the control diet. All the results in this study demonstrate that it is possible to include these ingredients derived from industrial waste in tilapia diets, improving the quality of the feed without affecting its performance.
