Dear Carlos;
I concur there is no Official Method for determining phosphates in seafood.
In our laboratory, we test for total phosphates and then water extractable
ortho-phosphates in the unknown sample and then we run the same two tests on
a sample of the seafood we believe in unadulterated. If the ratio between the
unknown sample's total and water extractable ortho-phosphates is much lower
than for the unknown, we believe this is indicative of adulteration.
Of course, phosphate compounds in seafood are legal if declared in labeling.
Many phosphates compounds can be added to seafood including: sodium phosphate
and sodium tri-polyphosphate and these will be detected as ortho-phosphates.
I hope this helps.
