    Author(s): S. Syed Raffic Ali*, K. Ambasankar and S. Nandakumar

    The present study was conducted to study the effect of varying levels of moisture content on extrusion properties of CIBA developed Asian seabass (Lates calcarifer) feed. The effect of addition of moisture was studied at 10%, 15%, 20%, 25%, and 30%. The trial was carried out in a pilot scale twin screw extruder (M/S. Jinan saibainuo Technology, China) with a capacity to produce 250 kg per hour. All the machinery parameters and feed processing factors were kept constant but for the moisture content. All the six feed mix were subjected for extrusion and the trial was repeated thrice. The results of the extrusion trials revealed that there was no extrusion of the feed mix containing moisture up to 15% and the extrusion process has just started at 20% moisture level. Feed mix containing 25% and 30% moisture showed efficient extrusion resulting in good expansi.. View More»
