| Summary: | Bread is one of the main symbols of the culinary heritage of Galicia (NW Spain). This study evaluates the nutritional quality of Galician breads made from local wheat varieties, ‘Caaveiro’ and ‘Callobre’, under organic and conventional farming systems. Breads were prepared using 100% local wheat flour and a mixture of 25% local flour with 75% commercial flour, in accordance with the Protected Geographical Indication (PGI) ‘Pan Galego’. Nutritional composition was assessed using official AOAC procedures and validated enzymatic assays, including macronutrients, fiber, starch fractions, sugars and minerals. The results reveal that 100% local wheat breads showed significantly higher levels of protein, carbohydrates and minerals, which are beneficial for human health. Specifically, ‘Caaveiro’ breads were richer in protein, while ‘Callobre’ breads exhibited higher carbohydrate and mineral content. Although the cultivation system had a minor effect, it was still relevant when combined with the proportion of local flour. The study highlights the potential of local wheat varieties to enhance the nutritional value of Galician bread. |
