Parámetros de Calidad y Metodologías para Determinar las Propiedades Físicas de Alimentos Extruidos para Peces

Abstract: ResumenEl presente trabajo relaciona los métodos tradicionales usados para analizar la calidad física de un alimento extruido para peces, como dureza, durabilidad, estabilidad en agua, velocidad de hundimiento, densidad aparente, capacidad de absorción-pérdida de aceite y porosidad como métodos para en el control de su producción a nivel industrial. Las propiedades físicas de los pellets son relevantes para la toma de decisiones relacionadas con las condiciones de procesamiento, transporte, almacenamiento, apr… Show more

“…Feed consumption differed slightly between diets, suggesting the higher palatability of fishmeal-based diets. As shown in the current study, and previous studies, shrimp fed extruded pellets had higher final body weights and significantly higher body lengths despite lower feed intake, attributed to better water stability and nutrient retention in extruded pellets (Hoyos et al, 2017;Jescovitch et al, 2018;Soares et al, 2021). The slow feeding behaviour of shrimp can result in increased nutrient leaching and loss prior to ingestion, a crucial consideration when substituting fishmeal with alternative components like soybean, which may require the supplementation of essential crystalline amino acids (CAAs), such as lysine (Simon et al, 2021).…”

“…In our study, the control diet was the more stable, whereas the experimental diets were more unstable. The relationship between stability and nutrient leeching has been discussed elsewhere (Fagbenro and Jauncey 1995), as well as the influence of experimental ingredients in the stability of fish diets (Hoyos et al 2017). This degree of disintegration is surely one of the reasons for the higher unaccounted nitrogen for the experimental diets (FM and VM) in comparison with the control diet, which was more compact.…”

“…The degradation rate was determined using the method described by [12]. Therefore, 2 g of the pellet was placed inside a 150 ml Pyrex beaker containing 100 ml of distilled water with a magnetic stirrer.…”
