Due to favourable protein/starch ratio, rice/buckwheat flour mixtures were used as ingredient for gluten-free cookies preparation. Although characterised with different particle size distribution than the wheat flour.
micrographs presented the structure was consisted presumably of small densely packed rice starch granules incorporated in interrupted protein. The starch granules were intact in spite the thermal treatment due to insufficient amount of added water in all of the used cookie formulations.
In order to determine the influence of gluten-free cookie formulation on macroscopic level, sensory analysis and colour measurements were performed. Namely, the top and bottom surface colour of baked cookie is very important parameter in initial acceptability of tested product by consumers
According to sensory analysis, presented in Table 6, wheat flour cookies expressed the lowest scores for sensory attributes such as shape, upper and bottom surface appearance, rupture and chewiness
