Opis:
The main aim of the study was to determine selected characteristics of extruded snacks supplemented with Dracocephalum moldavica L. seeds added to the recipe in amounts ranging from 5 to 20% of the basic raw material composition. The effect of the screw speed on the selected corn-based snacks characteristics has also been been studied. A single-screw extruder was employed to obtain the snacks in the form of readyto- eat extrudates. Several properties were evaluated, among them: the expansion ratio, the water absorption and solubility indices as well as pasting properties, depending on the level of the additive and the screw speeds applied. Extruded snacks supplemented with Dracocephalum moldavica L. seeds exhibited an enhanced nutritional value compared with corn snacks due to the high content of fibre, protein and ash. The addition of the seeds decreased the expansion ratio significantly. The water absorption index of the snacks decreased as the level of seed addition in the processed blends was raised, while the water solubility index was significantly affected by the variable screw speed during the processing of the supplemented snacks. The recommended level of Dracocephalum moldavica seeds in corn-based snacks should not exceed 15% due to the high nutritional value as well as the high expansion and efficient treatment intensity of the components resulting in the ready-to-eat characteristic of the supplemented snacks.

Opis:
The extrusion-cooking technique may be used to convert the common bean into functional food products. There is still insufficient information on the properties of extruded beans. The aim of this work was to investigate the effect of extrusioncooking conditions on the pasting properties of two cultivars of the common bean (Aura and Toska) available on the Polish market. The bean was extruded using a twin-screw extruder at variable screws speeds and different amounts of water were added directly to the barrel. The pasting properties of the obtained extrudates were measured using a Micro Visco-Amylo-Graph. The extruded beans revealed more stable viscosity characteristics than the unprocessed ones. The addition of increased amounts of water to the processed material raised the peak viscosity of both extruded bean varieties. A higher screws speed during bean processing resulted in a higher peak viscosity only in the case of the Aura cultivar. However, the decreasing value of the cold paste viscosity was observed at higher speeds. This may indicate the negative effect of the extruder’s screws speed on the gel formation ability of the extruded bean. The results showed that the extrusion-cooking process reduced the retrogradation tendency of bean paste due to starch degradation occurring during processing.
