Summary:

At one-month intervals during the four-month storage (20 ± 2 °C) changes in the organoleptic properties (scoring evaluation of shape, surface, colour, consistency, odour, taste and profiling of tastiness) and aw values of amaranth-based snacks and crackers were investigated. The changes observed during storage in the surface, colour and consistency of snacks (score 0.1-0.3 out of 5) and in the odour of crackers (score 0.2-0.3 out of 4) were insignificant. The taste harmonized in both samples having as a result higher scores with regard to the starting values. Although the aw values of products during storage varied to some extent (from 0.15 to 0.34), they did not influence the important sensory parameters (snacks crispness, crackers crunchiness).
