Vacuum packed tuna and swordfish
« on: August 11, 2016, 04:24:59 am »
Has anyone seen what is written on the sticker of the vacuum packed tuna and swordfish fillets as the are delivered to the fishmongers? I saw it and it's written (from memory):
Contents: Tuna (or swordfish), salt, glutamate, E300, E350.
Cause and effect are distant in time and space in complex systems, while at the same time there’s a tendency to look for causes near the events sought to be explained. Time delays in feedback in systems result in the condition where the long-run response of a system to an action is often different from its short-run response. — Ronald J. Ziegler

E300 is labeled in the US as ascorbic acid, and it is used to prevent food from oxidizing. E350 is some other acid, probably used for the same purpose.

Here in the US, a lot of cut fish are delivered wet packed, meaning that the cut surfaces of the fillets have been coated with sodium tripolyphosphate. The reasoning is that they are "fresh" this way. STPP is a salt that keeps things moist, even to the point of adding water weight. That's another good reason to buy the whole fish and a use your own knife.

A salt that keeps things moist?

Does that come from the same place as the water that keeps things dry?

Salts are hydrophilic. I'm not sure why you have a problem with that. Sometimes, table salt is sold with anti-caking agents added to prevent the salt from attracting moisture out of the air.

Salts can be used as laxatives, too, based on the same principle: drinking a salt solution with attract water into the colon, up to the point of diarrhea.

I wasnt saying i have a problem with it, just making an observation.

It was a commentary on my observation that for a salt to keep things moist it mut highly artificial and likely extremely toxic

I sometimes buy tuna steaks from TraderJoes.  The label does not list any additives. And tuna is brownish in color meaning it did not get carbon monoxide treatment like tuna used for sushi.

I try not to get any meat thats sealed. Im not sure of the bad affects other than the toxins in the plastic rubbing on the meat but it always tastes really different to me so I suspect the airtight seal in plastic contributes to some weird bacterial growth.
