Transformation of Agro-Industrial By-Products into High-Value Animal-Derived Foods: Bioactive Compounds, Microbiome-Mediated Biotransformation, Metabolomic Traceability and Circular Valorization.
Review in Molecules (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
Agro-industrial by-products are increasingly considered as feed resources for circular animal production, but their value should not be interpreted only as a low-cost replacement of conventional ingredients. This scoping review critically examines how by-products from grape, olive, tomato, citrus, cereal, brewery, oilseed and vegetable processing chains may contribute to the development of high-value animal-derived foods. Particular attention is given to bioactive compounds, polyphenols, carotenoids, tocopherols, fermentable fibres and residual lipids, as well as to microbiome-mediated biotransformation, host metabolic pathways, compound transfer, product-quality modulation, feed safety and circular valorization. Available evidence indicates that selected by-products can influence milk, cheese, meat, eggs and fish products by modifying fatty acid profile, oxidative stability, antioxidant-related traits, pigmentation, volatile compounds, shelf-life and, in some cases, the transfer of specific metabolites to edible products. However, these responses depend on by-product source, processing method, inclusion level, active dose, animal species, basal diet and analytical endpoints. Chemical richness alone is therefore insufficient to support functional claims. Stronger evidence requires studies that connect matrix characterization, processing stability, microbial and host-mediated transformation, biological intermediates and final product quality within the same experimental design. Precision circular feeding should therefore combine local availability, safety, active-dose definition, metabolomic and lipidomic traceability, and product-level validation to support reproducible improvements in high-value animal-derived foods.
