A study focusing on the distinct fine structure of starch in mealy and waxy potatoes.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
In this research, we examined the fine structure of starch in three mealy and three waxy potato varieties to understand their impact on potato texture. This research revealed significant variations in starch granule morphology, particle size, crystalline structure, molecular structure, and pasting properties between the different textures. Mealy potato starch granules appeared as rounded ovoid with inconsistent particle sizes (ranging from 35.9 to 41.8 μm), whereas waxy potato starch granules exhibited sharp polygonal shapes with consistent larger sizes (42.1-49.7 μm). While both types displayed a B-type crystalline morphology, the relative crystallinity of mealy potato starch (31.28%, 38.00% and 29.07%) is higher than that of waxy potato starch (27.38% 26.68% and 26.12%) as determined by X-ray diffraction. Additionally, the mealy potato starches had lower amylopectin content, degree of branching, short-chain amylopectin content, and molecular weight, but higher trough viscosity, final viscosity, and setback value than waxy potato starches. These differences in fine structure contributed significantly to the variations in texture between mealy and waxy potato starches, highlighting potential implications for breeding programs aimed at improving specific textural attributes for targeted application in the food industry.
