Designing nutritionally improved waffles containing glycerol monostearate based oleogel and aquafaba.
Article in Journal of the science of food and agriculture, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPlant-based diets are considered healthier and more sustainable, while solutions are sought to replace saturated fats in foods products. Aquafaba (AF) from chickpea cans was foamed to formulate waffles. AF was concentrated at three dry matter contents. Gluten-free oat flour and an oleogel (OG) containing 50 g kg
resultsFourier transform infrared analysis revealed protein specific peaks that are responsible for the foaming properties of AF. Concentrated AF had a gel-like behaviour (G' > G''), caused by the denaturation of proteins. AF21 was significantly stronger (G' = 89.22 ± 3.17 Pa) compared to AF14 (G' = 3.81 ± 0.3 Pa). Dough samples with AF7 and OG had a significantly higher hardness at the same whipping time compared to their oil counterparts (e.g. 10.78 ± 0.16 N for sample 6 versus 4.81 ± 0.34 N for 8). Waffles' springiness was low due to the gluten-free oat flour. A positive correlation (r = 0.743) was found between protein and hardness. One formulation was chosen for the sensory evaluation based on the principal component analysis. Principal component (PC) 1 accounted for 60.2% of the variance and PC 2 explained 24.4%. All samples had low hedonic scores and the most preferred sample was the control with wheat flour.
conclusionThis study demonstrates that AF concentration and the usage of OG influence the characteristics of waffles. © 2026 The Author(s). Journal of the Science of Food and Agriculture published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.
