Gellan Gum Modification and Structural Regulation for Food Applications: Delivery Systems and Digestive Behavior.
Review in Foods (Basel, Switzerland), 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
Gellan gum (GG) is an anionic microbial polysaccharide widely used in foods because of its efficient gelation, thermal stability, and ion-responsive structuring. However, the contrasting limitations of high- and low-acyl GG, together with their sensitivity to molecular weight, ions, pH, thermal history, and food-matrix composition, restrict their performance in complex products. This review distinguishes four intervention levels of GG modification and structural regulation: covalent modification, chain-architecture regulation, supramolecular regulation, and food-matrix composite structuring. These modifications and structural regulations alter chain properties, helix association, junction-zone formation, interfacial organization, and phase connectivity, thereby affecting gelation, texture, water retention, emulsion stability, processability, and release behavior. Food applications are evaluated through their structure-function relationships across diverse food systems. Particular attention is given to gastrointestinal disassembly, nutrient digestion, bioactive release, and colonic fermentation. Current evidence strongly supports the role of GG structural regulation in food texture and physical stability, whereas evidence for digestive modulation and physiological effects remains limited and is largely based on formulation-specific in vitro studies. Overall, this review provides a structure-guided framework for application-specific selection of GG intervention strategies.
