Hello all,
I'm working in a seafood processing industry and we are figuring out how to conduct validation on the process "soaking the prawns in sodium metabisulphite solution". FYI, the general process goes like this:
Receiving (CCP1) > Washing > Sizing > Weighing > Soaking in sodium metabisulphite solution (CCP2) > Weighing> Arranging > Freezing > Glazing > Metal Detection (CCP3) > Packing > Cold Storage
We have two concentrations for sodium metabisulphite solution (5% w/v and 1.5% w/v), and the soaking time is ten minutes. The concentration of sulphur dioxide should not be more than 150 ppm in edible part of prawns.
Is there any way to do the validation on this step (CCP2) or any idea on this? Or it actually is not necessary to be a CCP?
Thanks in advance.
