Evaluación del concentrado de pectina de cítrico como aglutinante en el alimento para camarón.

Abstract

Con el objetivo de evaluar el efecto aglutinante del concentrado de pectina de cítrico (CPC) en el alimento para camarón, se desarrolló un diseño experimental completamente aleatorizado con cuatro tratamientos y tres réplicas por cada uno, en condiciones controladas. Las dietas se elaboraron con 0; 2; 5 y 7 % de CPC. Las pruebas de estabilidad del alimento se realizaron introduciendo 1 g de cada alimento, en bolsas de 0,1 mm de luz de malla previamente pesada y se colocaron en agua de mar (35 ups y 27 ºC), durante 1; 12 y 24 h. Al final de cada intervalo de tiempo, los alimentos se secaron y pesaron para calcular peso seco, pérdida de materia seca y absorción de agua. Con el empleo del CPC, los alimentos alcanzaron una estabilidad superior al 80 % después de 24 h de inmersión en agua, superior a la lograda cuando no se incluyó el aglutinante. Al correlacionar la pérdida de materia seca de las dietas con los tiempos de exposición al agua, se alcanzaron coeficientes significativos de R2 = 0,944 2; R2 = 0,972 5; R2 = 0,911 8 y R2 = 0,851 4 respectivamente. El porcentaje de absorción de agua del alimento varió en dependencia del tiempo de inmersión y fue similar entre tratamientos transcurridas 12 h. A las 24 h, la dieta que incluyó 0 y 2 % de aglutinante, alcanzó valores de absorción significativamente mayores (p < 0,05) que el resto de las fórmulas. In order to evaluate the binding effect of citrus pectin concentrate (CPC) in crustacean food, a completely randomized experimental design was developed, with four treatments and three replicates each, under controlled conditions. Diets were prepared with 0; 2; 5 and 7 % of CPC. Food stability tests were carried out in seawater (35 ups and 27 º C), where remained for intervals of 1; 12 and 24 h. At the end of each period, dry weight, dry matter loss and water absorption was calculated. Food stability achieved with CPC, was over 80 % after 24 h immersion in sea water, superior to that achieved when binder was not included. Significant correlation coefficient were achieved between loss dry matter of diets and water exposure times, R2 = 0,944 2; R2 = 0,972 5; R2 = 0,911 8 y R2 = 0,851 4 respectively. The percentage of food water absorption varied depending on the immersion time and was similar between treatments within 12 h. At 24 h, diets without CPC and with 2 % binder, reached significantly higher water absorption (p < 0,05) than other. Published Citrus pectin concentrate Binding Water stability
