Jan:
I have read this professional exchange with great interest.
We have initiated testing on round fish preserved in ice produced with YPS
salt to detect compounds formed during storage, transport, and processing.
Your full story about the condition of these fish would help my people
greatly in our work and would contribute to designing technologies to prevent
this from happening in the future.
If fluids have penetrated into your refrigerated system I would recommend a
water solution containing 1% sodium citrate be scrubbed onto the surface of
your unit. Allow this to stand overnight. The following morning wash all of
the surfaces with a 5% water solution of baking soda. Then wash off the
residues with clean hot water.
Another useful blend would be to make a 1% water solution of equal parts of
citric and ascorbic acid and apply this to the unit. Allow the solution to
penetrate overnight and then react it with the baking soda as described above.
Good luck,
Marion Dewitty
