The objective of the study was to determine the chemical composition, the physical properties, and the cooking quality of commercially available whole grain pasta of wheat, spelt, and rye. In the tested assortments of pasta, there were determined the contents of protein, ash, total dietary fibre including soluble and insoluble fractions, and acid detergent fibre including cellulose and lignin. The water solubility index (WSI) and water absorption index (WAI) were also analyzed. The minimal cooking time for pasta was determined, as were the cooking losses of dry matter and the coefficient of weight increase after cooking. The whole-wheat pasta was characterized by the highest content of protein. The content of protein was about 16 % d.m. in two of four assortments of the whole-wheat pasta. The lowest protein content, ranging from 6.6 to 7.3 % d.m., was reported in the rye pasta. The ash content in the whole grain pasta was different and depended on the kind and type of flour used to produce pasta. The wheat wholemeal (graham) wheat pasta was characterized by the highest content of ash amounting to 2.3 % d.m. The content of total dietary fibre in the products tested highly varied in a range from 4.73 % d.m. (whole-spelt pasta) to 22.6 % d.m. (wholemeal wheat (graham) pasta). In the whole-wheat and whole-rye pasta, the insoluble fraction of the dietary fibre prevailed, while the soluble fraction of dietary fraction prevailed in the whole-spelt pasta. The whole-rye pasta was characterized by the highest values of cooking losses of dry matter exceeding 10%. The absolute majority of pasta assortments tested should not be classified as wholemeal or whole grain products.
