Scientists around the world are interested in edible insects as a source of valuable nutrients. Among the most often described are crickets, which represent a source of significant amounts of protein, lipids, vitamins, and minerals. This article reports results of a study into the effect of starch-to-cricket powder (CP) addition on the free amino acid profile as well as potential odorants in gluten-free (GF) bread. A significant 2.6-fold increase was observed in the content of essential amino acids in the CP-enriched GF bread. Moreover, the CP addition resulted in the formation of many volatile compounds, such as pyrazines, furans, and sulfur-containing compounds, which exhibit strong aroma-enhancing properties. The attractiveness of the CP-enriched bread was confirmed by the results of the sensory analysis, showing a significant improvement in its flavor when compared to the traditional GF bread without CP. GF bread enriched with CP was characterized by caramel, roasty, and cooked potatoes notes. On the basis of the obtained results, it was concluded that the use of CP not only improves the nutritional value but also aroma of GF bread.
