We do not add weight to our shrimp. Look at the ingredients of your shrimp. If it says something besides shrimp, beware.
Coapno Blues ingredient statement reads: Shrimp.
Watch out for salt, which can be used to add water and cover up off flavors. Other ingredients to be wary of include sodium tripoly phosphate, which is used to add water weight. Sodium bicarbonate and sodium chloride also are used instead of phosphate to add moisture.
Natural is better. Copano Blues are naturally delicious.
