Traditional Foods as a Way to Preserve the Genetic Diversity of the Grapevine (Vitis spp.) in Tunisia

Tunisia has a long tradition of viticulture, and the grapevine is used for a variety of traditional foods. The country has traditional plant-based dishes, which may have different compositions and names depending on the region of origin. Unfortunately, over the years, traditional preparations are no longer as popular as they used to be, due to both changing lifestyles and the introduction of new crops and foods. For example, the use of grapevine in traditional dishes has declined as traditions have been lost and habits have changed in favor of new, ready-to-eat foods. The close link between grapevine, culture and territory requires an appropriate evaluation and characterization of traditional foods in order to enhance and extend their use, ensure their sustainability and preserve the varieties used to produce them. This review analyzes the use of local grapevine varieties in different traditional dishes as a means to preserve an invaluable natural and cultural resource and heritage.
