Fabrication of collagen fiber films incorporated with different sourced hydrocolloids and the application in chilled meat preservation: a comparative study.
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
backgroundCollagen fibers are commonly used as raw materials for artificial collagen casings/films. Due to the inevitable disruption and reorganization during the processing, the re-prepared films have poorer performances, especially in mechanical properties. This study aims to explore the effects of different sourced hydrocolloids on the film-forming properties of collagen fibers, and also to evaluate the application effects on chilled meat preservation.
resultsDifferent hydrocolloids had various abilities to reduce the viscosity and modulus of collagen fiber dispersions. They improved the mechanical properties of the collagen fiber films, with two proteins (gelatin and soy protein isolate) showing more significant performance in dry tensile strength, while two polysaccharides (chitosan and corn starch) performed better in wet tensile strength. Chitosan and corn starch reduced the swelling ratio of the composite films, relating to their better wet mechanical properties. Different hydrocolloids also enhanced the thermodynamic stability of the films, with gelatin having the most significant effect. The addition of hydrocolloids did not significantly affect the structural integrity of collagen and they promoted the unfolding of collagen fiber bundles to a certain extent. Different hydrocolloids improved the preservation effect of composite films on chilled meat, with two polysaccharide substances having a more significant impact.
conclusionThis study analyzed the effects and mechanisms of different sourced hydrocolloids in the fabrication of collagen fiber film. They improved the performances of films to varying degrees and enhanced the preservation effect of chilled meat. This research could provide insights for the use of hydrocolloids in collagen fiber film systems. © 2026 Society of Chemical Industry.
