Title: HIGH PROTEIN, HIGH FAT EXTRUDED SINKING AQUATIC FEED
Abstract:
A method of producing extrudates such as high protein, high fat sinking aquatic feeds is provided wherein a high protein starting material is initially preconditioned and passed through an extruder (14); in the extruder barrel (36) a zone of reduced pressure is created upstream of the die (40) for densifying the final extrudate. Fat may be added to the starting mixture at any desired point in the process, and/or may be added as a surface coating to the final extrudate. Preferably, the method further involves measuring a density value of the extrudate such as bulk density, and adjusting the magnitude of the reduced pressure conditions in the barrel in response to such measurement.
