Chitosan-PVA composite films incorporated with roselle anthocyanins: Colorimetric smart sensor for real-time monitoring of meat and seafood freshness.

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
Ensuring freshness in perishable foods like meat and seafood is vital for food safety. This study developed a biodegradable colorimetric film from chitosan-polyvinyl alcohol (Cs/PVA) infused with roselle anthocyanin extract (CPAR) to monitor spoilage. Among variants, CPAR-5 (5 mL extract) showed the highest pH sensitivity (ΔE = 44.69, S% = 42%) and rapid response to ammonia vapor. Characterization via UV-Vis, FTIR, and FESEM confirmed effective pigment integration and film structure. Applied to chicken, shrimp, and tilapia, CPAR-5 visually tracked spoilage in real time under ambient and cold storage, correlating with critical pH thresholds (≥6.8 for chicken, ≥7.4 for shrimp, ≥7.0 for fish). A visual card reader was developed for semi-quantitative freshness evaluation, demonstrating that CPAR-5 is a highly sensitive, robust, user-friendly, and environmentally sustainable smart indicator with strong potential for practical food safety monitoring and reduce food waste.
