Effect of the concentration of agar, alginate and carrageenan on the stability, toughness and nutrient leaching in artificial diets for abalone

In order to evaluate the effect of different binders on the quality of artificial diets for abalone in terms of stability, nutrient leaching and toughness, three phycocolloids (agar, alginate and carrageenan) were used at different concentrations (0.5%, 1.0%, 1.5%, 2.0% and 2.5%), mixed with fish me...

Both stability and pellet toughness were influenced more by the protein source than by the type and concentration of the binder, as diets containing abalone viscera silage lost 20% dry matter, compared to the 10% lost in diets containing fish meal. However, nutrient leaching was not affected by the phycocolloid concentration. This result coincides with previous reports that leaching speed does not depend on stability. In general, all the binders used were effective at low concentrations (0.5%); therefore, the use of phycocolloids at low concentrations is recommended. Attention should also be given to the ingredients used, as these may have a greater influence on stability and toughness than the binders themselves. Para evaluar el efecto de tres ficocoloides (agar, alginato y carragenano) sobre la calidad de alimentos balanceados para abulón en términos de estabilidad, lavado de nutrientes y dureza, se prepararon alimentos balanceados con cada uno de los enlazantes a diferentes concentraciones (0.5%, 1.0%, 1.5%, 2.0% y 2.5%) y con dos fuentes diferentes de proteína: harina de pescado o ensilaje de vísceras de abulón. Los resultados muestran que tanto la estabilidad como la dureza se vieron influenciadas por el tipo de fuente proteica más que por el tipo y concentración del enlazante, ya que los alimentos balanceados con vísceras de abulón perdieron más del 20% de la materia seca, en comparación con los preparados con harina de pescado, que presentaron menos del 10%. Sin embargo, el lavado de nutrientes no se vio afectado por la concentración de los ficocoloides, resultado que coincide con lo reportado anteriormente de que la velocidad de lavado es independiente de la estabilidad. En general, cualquiera de los ficocoloides utilizados funcionó con buenas características a concentraciones bajas (0.5%); por esto, se concluye que los ficocoloides deben ser empleados en bajas concentraciones. Se recomienda poner atención al tipo de ingredientes utilizados, ya que éstos pueden tener una mayor influencia sobre la estabilidad y dureza que los mismos enlazantes.
