Effect of Moisture, Extrusion Temperature and Screw Speed on Residence Time, Specific Mechanical Energy and Psychochemical Properties of Bean Four and Soy Protein Aquaculture Feeds -

Abstract

The aim of this study was to evaluate the effect of moisture supply, temperature and screw speed on specific mechanical energy and functional properties of extruded feed for aquaculture bean flour and soy protein. Fishmeal was replaced by different concentrations of bean flour or soy protein. Subsequently, the diets were extruded and residence time, specific mechanical energy, absorption rate and solubility in water were analyzed. Temperature and screw speed had a significant effect (P
