Nine Scottish foodstuffs, including Scotch beef and Arbroath smokies, currently enjoy Protected Food Name (PFN) status.
Producers in Scotland are considering a number of applications for PFN status, for products such as Stornoway black pudding, traditional Ayrshire Dunlop cheese and Scottish wild salmon.
But Mr Lochhead wants more food producers to get in on the act.
He said: "Scotch beef and lamb, Scottish farmed salmon and Arbroath smokies all enjoy the benefit of protected food name status giving customers the guaranteed genuine article.
"There are over 800 protected PFNs registered across the EU, with Italy, France, Spain, Portugal, Greece and Germany accounting for around 90% of all PFNs.
"I would encourage more producers to apply to the scheme, giving Scottish products protection from inferior imitations.
"The sector supports Scottish farmers, fishermen, retailers, producers and suppliers, and I want to see even more being able to take advantage of both domestic and global markets."
Mr Lochhead recently announced that ministers plan to bring together producers who already have PFN status with those who are hoping to secure it.
A food must be produced, processed or prepared in the geographic area from which it originates to gain the special status.
Products which achieve the standard can then benefit from legal protection against imitation throughout the European Union.
Mr Lochhead is visiting the Anuga Food Fair in Cologne, Germany, today to support the exhibitors taking Scottish produce to an international audience.
He will also unveil a new branding to help boost the profile of Scottish food and drink.
