Six varieties of proso millet (<i>Panicum miliaceum</i> L.) and two commercially available millets were investigated in the present study. In order to explore the nutritional potential, major nutrient composition, mineral composition, antioxidant capacity, total phenols content (related to the antioxidant capacity) and dietary fibre content were determined. The effects of decortication on these components were examined. In addition, protein profile of the varieties and amylose/amylopectin ratio of the starch were examined. The range of the values measured for major nutrient composition corresponds with data of other millet species published in earlier studies. Remarkable differences were found among the protein contents of the varieties (11.58–14.80%). Although the concentration of minerals was low in the varieties examined, in comparison with other cereals wholegrain millet seems to be nutritionally valuable because of their high dietary fibre content. Decortication had no effect on the protein and fat content of millets, however, it significantly decreased the content of crude fibre, dietary fibre, minerals, total phenols content and antioxidant capacity. Consequently the applicability of millets as functional food decreases. Decortication had no effect on the amylose/amylopectin ratio of millet. No varietal differences were found in terms of protein characteristics.
