What do tuna fish eat? Tuna is omnivorous and feeds mostly on small fish.
How can I preserve leftover tuna? A small piece of advice for all types of tinned tuna is that, if the product is not consumed all at once, it should be left in the tin if possible. Add some fresh olive oil until the fish is completely covered, wrap it in cling film and put it in the fridge. It should then be eaten preferably within 2 or 3 days.
How is the tuna cooked? Before being tinned, the tuna is steam cooked and then hand processed, just like in the old days, to guarantee meticulous cleaning and maximum quality levels.
I’ve heard people speaking about the tuna fish ageing process. What exactly is this? The final phase of tuna processing is ageing, in the course of which the finished product is left to lie for a period ranging from a fortnight to several months, according to formats. It allows the oil to penetrate into the fibres of the fish, thereby making it more tender and tasty.
How long does tuna keep in the tin? The date by which the product should be eaten so that its organoleptic features remain intact is always indicated on Rio Mare tins and packets. It is best to consume tuna in olive oil within five years from the date of production, while tuna in brine should be eaten within 3 years. However, as regards health specifications the preservation time of the product in its container is indefinite.
Is there any oil in the ingredients of tuna in brine? No. The tuna is preserved in brine (water and sea salt) with a possible addition of natural flavours or aromatic plants.
What are the tins made of? The tin may be made of tin plate, i.e. high quality steel covered in pure tin which makes the container robust and impenetrable and guarantees against rusting. Another material used, for example in the new Rio Mare Insalatissime trays, is aluminium which, besides being suitable for contact with food, is also light and easy to open.
What is Omega 3 and is it to be found in tuna? OMEGA 3 are fatty acids which may prevent cardiovascular and coronary diseases, to say nothing of the fact that they play a fundamental role in the cerebral development of humans and may also have a preventive effect as regards many other disturbances. If we eat more fish or dietetically similar products, our Omega 3 intake will be boosted. The main sources of OMEGA 3 fatty acids are in fact fish (salmon, herring, mackerel, sardines, tuna) and fish oil.
Is tuna indicated for small children? Absolutely. Tuna has a high biological value and its proteins contain all the amino acids needed for feeding children, including babies.
How come tuna keeps for so long? Does it contain preservatives? No, tuna does not contain preservatives. Preservation is guaranteed by means of thermal treatment at 121° C on the sealed tin, which destroys any remaining micro-organisms that may still be present.
