Abstract : The economic importance of Shea tree fruits has been rising and achieving a great success in African, American, European markets. In Europe, Shea butter is used mainly (95%) by the chocolate industry. The quantities exported to Japan, the United States or Switzerland would be mainly used for cosmetic or pharmacological (FAOSTAT, 2007). The traceability of fruits is only documentary. In case of doubt or fraud, no standardized analysis makes it possible to trace back the origin of the fruit. The aim of this study is to use a new tool of tracing the products (PCR-DGGE) as a molecular technique to analyse in a unique step all the yeasts present on the fruit to create the linkage between yeast communities and the geographical origin.(Résumé d'auteur)
