Postbiotics in Food Systems: Components, Production Methods, Food Applications, Functional Properties, and Technological Challenges.
Review in Food science & nutrition, 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
The functional food industry has increasingly focused on postbiotics due to challenges associated with maintaining probiotic viability and safety concerns in immunocompromised individuals. Postbiotics are defined as inanimate microbial cells and/or their metabolites that do not require viability but retain health promoting properties and technological stability. This stability has positioned postbiotics as promising alternative ingredients for food engineering applications where processing robustness is critical. This review provides a comprehensive, engineering-oriented evaluation of postbiotics as next-generation functional food ingredients. Current definitions and classification schemes are first summarized, followed by an assessment of how innovative thermal and non-thermal production methods can be integrated into food processing systems. Analytical and advanced characterization techniques used for the qualitative and quantitative assessment of postbiotics in food matrices are then examined, alongside a comparison of the technological advantages and safety profiles of postbiotics relative to probiotics. Applications across different food matrices are reviewed and summarized in detailed tables, and commercially available postbiotic products are compiled together with their key specifications. Major challenges limiting broader industrial adoption are also addressed, including interactions with food components, the absence of standardized inactivation protocols, regulatory uncertainties, and the lack of harmonized industrial-scale production methods. By consolidating these dimensions, this review identifies key research gaps, particularly the need for standardized inactivation and characterization protocols that can support regulatory alignment and evidence-based health claims and outlines future directions to improve process efficiency and support the development of safe, sustainable postbiotic-based foods.
