The aim of this study was to determine the effects of different proportions of defatted blackcurrant seeds on the nonstarch polysaccharide, sugar, starch and vitamin C content and the basic physical properties of cereal extrudates. The analyzed extrudates were based on cornmeal, which was partly replaced with blackcurrant seeds in proportions of 10, 30 and 50%. It was observed that the addition of seeds caused elevation in fiber and hemicelluloses compared with the control; the beta-glucan content in all analyzed samples was negligible. The vitamin C content in extrudates with seeds was several times higher, but the amount of starch decreased and the level of sugar increased in comparison with control. Extrudates with seeds added were characterized by higher water-binding capacity and solubility in comparison with a control (with the exception of that with 50% seeds). It was shown that the addition of seeds increased the density and reduced the expansion of extrudates.
