The recent Protected Geographical Indication (PGI) of ‘Pan Galego’ (Galician bread) requires that the flour comprise a minimum 25% local wheat cultivars. As a test for compliance with this minimum level, wheat flours were prepared by mixing commercial flours with 0%, 5%, 20%, 25% and 30% ‘Caaveiro’ and 100% ‘Caaveiro’ and 100% commercial flours were used as controls. A second analysis was performed with a second set of wheat flours with 5% and 25% ‘Caaveiro’. These were mixed with two different commercial flours to assess the potential ability of five SSRs to identify the percentage of ‘Caaveiro’, constituting the first reference of the use of SSRs in the traceability of specific autochthonous cultivars in flour blends. ddPCR using the QX200 system platform was used to the targeted proportions across the simulated range with two out of five SSRs, indicating that they can be used in the traceability of ‘Caaveiro’ in mixed flours and breads PB Wiley YR 2022 FD 2022 LK http://hdl.handle.net/10347/29257 UL http://hdl.handle.net/10347/29257 LA eng NO Ramos Cabrer, A.
