Single screw extrusion processing of soy white flakes based catla feed.

摘要: An initial investigation into the inclusion of soy white flakes (SWF) and high protein distillers dried grains (HP-DDG) in catla (Catla catla) diet, belonging to family Cyprinidae, was conducted using a single screw extruder. Three isocaloric (302 kcal/100 g) ingredient blends containing graded levels SWF combination with HP-DDG other required ingredients were formulated contain net content 31.5% (wet basis). Extrusion processing then performed three each content, moisture temperature gradient keeping constant speed die diameter. Effects these variables on extrudate physical properties including: color, pellet durability index, bulk density, water absorption solubility unit density expansion ratio extensively analyzed. Increasing level resulted increase index but decrease ratio. The interaction effect significant for All extrudates showed relatively produced less expanded more compact textured extrudates.
