The modified technology for processing of canned fish products having the functional food properties has been worked out. The technological modification excludes presalting and precooking operation of fish raw material out of the standard production process. It has been shown, on the basis of experimentally produced canned fish products, that there are technological possibilities to produce various assortments of such functional food with presupposed composition and nutritional value. Canned products produced from Atlantic mackerel (Scomber scombrus) could be recognized as functional food, due to well balanced content of basic nutrients, and especially due to high content (above 3g/100g) of n-3 PUFA.
