Popular food products can be used in regional branding. Names and trademarks of 56 Russian producers of sunflower oil which is nationally high-demanded culinary oil are analyzed to find indications of regions. The regional affinity is classified and scored. It is found that about a half of the considered producers indicate region of location in their names and/or trademarks. Often regions are considered directly although some producers mention them in unclear or allegoric ways. Many region-concerned producers concentrate in the Altai Rostov and Krasnodar regions. These findings indicates on the urgency of support of the region-related naming by regional administrations and professional associations.
