Phosphates are very common in commercial products like Hot Dogs, Cold Cuts(Ham, Turkey, Bologna)and with Shellfish. It helps bind ground meat proteins and fat for emulsification and retains moisture in the sausage or meat. But Phosphates can be misused as well. A Deli I worked in carried 35% water added Ham. The stuff must of had the USDA limit of Phosphate in it to retain that amount of water. It was cheap and the small print on the sign said " water added" but few realized what they were paying for. Probably the biggest abuse of Phosphate is with shelfish. Soak 31-40 count Shimp, $5.99/lb, in water and Phosphate and they swell up to 21-25 shrimp, $7.99/lb, until they are cooked and shrink back to their true size. Pretty good scam! Scallops too. You usually see these as Big Scallops swimming in a bowl of milky water. They are safe to eat and tasty but your are paying for water. These Scallops can be sauteed or grilled but will never sear golden brown and the breading blows off if you deep fry them. Pay the extra for Dry Scallops that have no added Phosphate...JJ
