abstract: Sensory parameters of gluten-free bread depend on the amount and type of hydrocolloids used as gluten replacers, as this determines interactions between them and starch, which is the main component of dough. The evaluation of gluten-free breads supplemented with various amounts of guar gum, pectin and xanthan, proved that bread with addition of xanthan has higher volume in comparison with pectin-guar standard. Higher amount of xanthan resulted in a decrease of bread hardness on the day of baking and after 72 hours of storage. Bread baked with equal amounts of all hydrocolloids (recipe IV) displayed best quality parameters. The amount of free amylose in crumb extract depended on the extent of starch gelatinisation, influenced by proportions of pectin, guar gum and xanthan in the mixture of hydrocolloids.
