The initial product selected as the object of study (selected
as the functional unit within the life cycle assessment) is a 2-
kg tray of pasteurized tuna with tomato. This is a common
product currently commercialized at a national level and is
a typical dish in Spanish cuisine, where elaborated fish dishes
are widespread and tuna is one of the most popular fish in
Spain. The cooked tuna with tomato dish has been selected
to carry out this pilot eco-design because it presents one of
the highest complexity levels in the food sector, due to the
fact that it has a high number of raw materials of different international
origins and many life cycle stages. It is also
a multi-process product.
