Modern consumers are more concerned about the safety and quality of food they consume. In this way changes are inevitable in the cultivation of raw materials, their processing and marketing. The main aim of this study was to investigate and to compare the quality of the great pumpkin’s 'Justynka F1', 'Karowita' fruit flesh and the blue fleshed potatoe’s 'Blue Congo', 'Vitelotte' tubers. Standard methods were applied to identify the following: dry matter, crude protein, crude fibre and crude ash. It was performed a comparative analysis of the results. Research results showed that the highest quantity of the dry matter have been found in potato cv. 'Vitelotte' (23.7 %). The flesh of cv. 'Karowita' is valuable due high crude protein (11.90 % d. m.) and crude fibre (6.38 % d. m.) content. The fruit flesh of cv. 'Justynka F1' is rich in crude ash – 8.89 % d. m.
