Quality assurance of functional food products using physical field-assisted freezing.
Review in Frontiers in 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 quality of functional food products depends on the content of biologically active compounds throughout their shelf life. Freezing provides a significant increase in the shelf life of food products. At the same time, conventional food preservation by freezing appears to diminish the content of functional ingredients due to food structure damage and oxidation. This leads to significant losses of biologically active substances and a reduction in the product's biological activity. Depending on the type of biologically active substance these losses can reach 80%. Enhancing functional ingredients stability is suggested to be achieved using field-assisted freezing techniques. Electromagnetic field-assisted freezing improves retention of L-ascorbic acid in comparison with conventional methods, while ultrasound-assisted freezing improves total phenol retention by 15%, minimizes drip loss, and reduces lipid oxidation. Reported effects vary substantially with processing settings, and evidence for functional food products is still sparse, calling for ingredient- and matrix-specific studies.
