Development of a water solubility model of extruded feeds by utilizing a starch gelatinization model

This study aimed to estimate the effects of extrusion variables on extruded aquafeed water solubility using a starch gelatinization model. A new equation was derived from classical degree model calculate solubility. After considering data five formulations, average absolute deviation (AAD) 7.97% for extrudate and 2.24% index. In most cases, index increased with an increase in process screw speed temperature but decreased decrease content. On other hand, when moisture content 0.2 0.3 kg/kg, 4.91 5.22% (wt) typical recipe low process. The established way quantitatively elaborate relationship between variables.
