Microbiological, nutritional and sensory evaluation of long-time stored amaranth biscuits produced from irradiation-treated amaranth grain.
The paper presents some results achieved by the evaluation of microbiological (total bacterial count, coliform bacteria, aerobic sporeforming bacteria, yeasts and moulds), nutritional (lysine) and sensory (shape, surface, colour consistency, taste, odour, the profiling of tastiness) quality and of the aw values of amaranth-based biscuits produced from the amaranth grain irradiated by various ionizing radiation doses (1.5, 3 and 5 kGy, source 60Co) and stored for the period of 12 months at the laboratory temperature (20-25 degrees C). The irradiation dose providing the biscuits maximum hygienic, nutritional and sensory quality maintained up to the end of the one-year storage was 5 kGy.
