The main issue associated with chilling post-mortem prior to gutting is ensuring chill rates are optimal for shelf life and quality and the efficiency of the gutting process with the aim to pack gutted fish as close to 0 C as possible. Many existing processes actually deliver fish too cold to gutting which causes a type of "false rigor" leading to gutting machine miscuts, gut and kidney residue, and increased fish bypassing to manual lines.
Post-gut chilling is not often used but is very efficient and the few process lines that have adopted this approach have seen large benefits. Simply add a small screwchiller for example after the gutting line and get a rapid drop in temperature due to the body cavity being open. Read more ...
