Why do they add algin to frozen food ?

I know they call it "binder", but why do we need binders?
I was in understanding that when purchasing frozen krill
or artemia I am buying krill+water only, no additives...
Are they any adverse effects of adding large amounts of
algin and other binders to our tanks ?

I don't know, but I've been rinsing frozen foods for a while now. I defrost
it in some RODI and the water has a strong orange or brown tint, depending
on the food. I pour that into a medium density fish net and rinse with a
glass or two of RODI. Then I invert the net and pour more RODI over it and
back into the glass. The water ends up being clear with large floating food
particles.

Since now I was in the understanding this brown tint are
ruptured cells which are destroyed in the freezing process.

And since I considered this to be beneficial for my filter feeder
animals I have not rinsed thawed food before feeding...

Now, after reading about binders like algin I have second thoughts.
But algin is derived from algae, so it sounds "safe" - go figure! ;-)
