Abstract: The aim of this study was to characterise gluten-free breads formulated with alternative flours through technological and sensory (ultra flash profiling, hedonic tests) properties, and to correlate both methodologies for holistically understanding how these variables affect the consumer preference and product quality. Gluten-free breads formulated by replacing 20% with brown rice, lupine, millet, quinoa, sorghum, teff, buckwheat, rice bran and carob flours were evaluated. The dough hydration and fermentation times were optimised. The formulations presented differences in centesimal composition, specific volume, texture and colour. Significant correlations were established between fermentation time, specific volume, centesimal composition, texture (hardness, gumminess), alveolar structure (porosity, uniformity, cell density), colour (L*), sensory descriptors and overall acceptability. The ultra flash profiling test confirmed different sensory profiles, showing that some descriptors have a high impact in overall acceptability. Multiple factor analysis contributed to understand the interrelationships between technological and sensory properties, identifying the relevant technological parameters that affect the consumer preferences and the final product quality.
