The Effects of Die Temperature and Screw Speed on Extruded Pulse Flours and Their Application in Bread Production.
Article in Food science & nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Extrusion is an innovative technology for improving the techno-functional and nutritional properties of pulse flours. This study aimed to optimize extrusion conditions for broad bean and mung bean flours and to assess their potential in bread making. Die temperature (135°C-165°C) and screw speed (200-300 rpm) were optimized using response surface methodology, with water absorption index (WAI), phytic acid (PA), and insoluble dietary fiber (ISDF) as response variables. Optimal conditions were found to be a 165°C die temperature and a 200 rpm screw speed for both pulses. Die temperature and screw speed had a significant effect on WAI, PA, and ISDF values. Flours obtained under optimum conditions showed the following changes: in mung bean, WAI increased by 50%, whereas PA and ISDF decreased by 59.5% and 30.9%, respectively; in faba bean, WAI increased by 33.69%, whereas PA and ISDF decreased by 45.27% and 29.68%, respectively. Extrusion disrupted starch crystallinity and changed protein-carbohydrate structures as observed by XRD, FTIR, and DSC analyses. Incorporation of pulse flours affected the rheological properties of the bread dough, causing a decrease in viscous and elastic responses. In bread making trials, wheat flour was substituted with pulse flours at 12.5% and 25%. Both substitution levels reduced bread volume and increased crumb hardness. In conclusion, it is shown that extrusion is an effective method for modifying the functional properties of pulse flours, and the use of optimized extrusion as a tool to develop novel functional pulse-based ingredients.
