Cornish pasties are said to be crimped on one side and have a chunky filling
A bid has been started to obtain European protection for the term "Cornish pasty".
South West MEP Graham Watson is meeting a European Union commissioner in Strasbourg as part of efforts to ensure the product gains EU protected status.
If granted, it would mean only pasties made in the county to a certain style could be officially called Cornish.
Other items from the county already on the protected list include Cornish clotted cream and the Cornish sardine.
Pasty makers in the county won the backing of the Department for Food and Rural Affairs (Defra) to take their case for Protected Food Name (PFN) status to the EU in 2008.
The bid states Cornish pasties would have to be made in the county, have a distinctive "D" shape, be crimped on one side - never on top - and have a chunky filling.
No other food would be able to use the name of a protected product and approval would give the humble "oggy" the same status as Roquefort cheese, French Champagne, Jersey royal potatoes and Newcastle brown ale.
Cornish clotted cream producers won similar status in 1998.
The Cornish sardine was granted its European status last December.
