Pollock, processed and frozen in Alaska, were thawed and mechanically filleted using a modified LaPine filleting machine. A Yanagiya flesh separator was used to prepare minced flesh from the fillet trimmings. In addition to standard hand‐packed fillet blocks, blocks were also prepared from randomly packed chopped fillets and chopped fillets mixed with varying amounts of minced flesh. The quality of the blocks was monitored during subsequent frozen storage by sensory and chemical tests. The results indicate that pollock is suitable for reprocessing. The quality of blocks prepared from chopped fillets was similar to that of conventional fillet blocks. Although minced flesh was less stable, an acceptable, but somewhat lower quality product could be made from a combination of fillets and 20% minced flesh.
