In the present paper, the measurement results were presented of some physical and culinary properties of extrusion-cooked instant pasta enriched with pea (Pisum sativum) added as pea flour (in the amount of 10 to 40 % of the wheat flour mass, according to the recipe used). The pasta mixture, its moisture content being 30 %, was extrusion-cooked at a temperature of 80 – 95 °C, in a single screw extrusion-cooker with a modified plasticizing and cooling section. The following parameters of the pasta products were determined: expansion ratio, water absorption, time of preparing pasta for eating, component losses during the hydration, texture and organoleptic features of pasta prior to and after it has been prepared for consumption. The expansion ratio of the products decreased along with the increase in the pea flour amount added to the pasta dough. The pasta products with pea added showed a higher water absorption level than the wheat pasta. The quantity of components passing into water during the hydration increased along with the increase in the pea flour added to the pasta dough. The time of hydration was from 4 to 8 minutes, and the pasta products obtained did not require to be cooked. The addition of pea caused the hardness of extrusioncooked pasta to decrease, both before and after they were prepared for eating. However, when too much pea flour was added (above 30 %) to pasta products, the sensory quality of the extrusion-cooked and enriched pasta decreased.
