Nutrient Content of Puffed Proso Millet (Panicum miliaceum L.) and Amaranth (Amaranthus cruentus L.) Grains

Puffed grains of the varieties of proso millet (Penicum miliaceum L.) and amaranth (Amaranthus cruentus L.) were evaluated as a source of nutritional compounds. The process of grain puffing was performed in prototype equipment of the Szarlat company. The analysed mean values for puffed grains were starch (proso millet 72.58%, amaranth 55.53%), fat (proso millet 8.43%, amaranth 8.99%), proteins (proso millet 13.89%, amaranth 14.04%), amino acids (proso millet 48.30 g/kg, amaranth 54.03 g/kg), crude fibre (proso millet 4.29%, amaranth 4.47%), and its fractions, as well as the total polyphenol content (proso millet 0.98%, amaranth 0.19%). Based on the results, puffed proso millet grains had the highest amounts of phenolic compounds and starch, and the lowest amount of crude dietary fibre and fat. Furthermore, both products were the sources of micro- and macrocomponents, primarily potassium, calcium, magnesium, and phosphorus.
