Fish Products with an Extended Shelf Life

These products with an extended shelf life can normally be kept indefinitely (in practice about 5 years). Special can materials have to be chosen when the fish is canned with corrosive ingredients such as tomato or mustard sauce, vinegar or lemon juice. The can is usually made of a lacquer-coated tinplate or inert aluminum. 

Products with extended shelf lives are in their own juice or in added oil, or in some sauce or cream (e. g. sardine pilchards, Sardina pilchardus, packed in olive or soya oil, tomato mustard, or lemon juice). Also available are fish paste, meat balls or Frikadellen (Germany), i. e. flesh of white fish made into rissoles using flour, eggs and spices, which are then roasted, deep fried and used ready-to-serve, as hors d oeuvres, and fish salad. The latter products are canned or packed in glass jars, and may be packed under controlled atmosphere.
