Research Progress in the Antibacterial and Antioxidant Effects of Chitosan-Based Hydrogels on Chilled Meat Preservation and Their Mechanisms.
Review in Comprehensive reviews in food science and food safety, 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
Chilled meat possesses a tender texture, desirable flavor, and enhanced safety. However, prolonging the shelf life of chilled meat is a significant challenge under conventional packaging methods. Chitosan-based hydrogels present a viable solution to this issue due to their ease of preparation and possession of antibacterial and antioxidant properties. This paper reviews the preparation of chitosan-based hydrogels from two aspects: methods (solution casting, self-assembly, freeze-thaw cycles, radiation, electrospinning, and three-dimensional printing) and influencing factors (pH, temperature, enzymes, ions, radiation conditions, and cross-linking agents). Second, the applications of chitosan-based hydrogels in chilled meat preservation are summarized and classified (antibacterial applications, antioxidant applications, freshness indicators, and barrier applications). Third, we elucidate the antibacterial (disrupting cellular structure, chelating intracellular components, and inhibiting genetic processes) and antioxidant (inhibiting chain oxidation, stabilizing structure, and maintaining function) mechanisms of chitosan-based hydrogels through multiple pathways and provide strategies to enhance preservation performance. We conclude that the composition (chitosan properties and functional components) and structure (microstructure and cross-linking degree) of chitosan-based hydrogels exert impacts on preservation performance. To better promote the industrial application of chitosan-based hydrogels, it is essential to optimize economic costs, establish standardized regulations, accommodate real-world environments, and integrate advanced technologies. This study offers novel guidance and future perspectives for advancing chitosan-based hydrogels in sustainable food preservation.
