Effect Of Different Extrusion Processing Parameters On Physical Properties Of Soy White Flakes And High Protein Distillers Dried Grains-Based Extruded Aquafeeds, Sushil Kumar Singh, Kasiviswanathan Muthukumarappan

Sushil Singh

Nutritionally balanced ingredient blends for catla (Catla catla), belonging to the family Cyprinidae, were extruded using single screw extruder. The extrusion was carried out at five levels of soy white flakes content (21%, 29%, 40%, 52%, and 59% db), five levels of moisture content (15, 19, 25, 31, and 35% db) and five levels of barrel temperature (100, 110, 125, 140, and 150 ºC) using three different die nozzles (having L/D ratios 3.33, 5.83, and 7.25). Blends with net protein content of 32.5% contains soy white flakes, along with high protein distillers dried grains (HP-DDG), corn flour, corn gluten meal, …
