Daidai Flower Essential Oil as a Multifunctional Natural Agent: Chemical Profile, Antimicrobial Activity, Preliminary Insecticidal Potential, and Improved Microbiological Quality of Fresh Arugula During Refrigerated Storage.
Article in Journal of food science, 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
This study evaluates the potential of daidai flower essential oil (DFEO) (Citrus aurantium var. daidai) as a natural preservative for fresh leafy vegetables. The chemical composition of DFEO was determined by gas chromatography coupled with mass spectrometry (GC-MS), revealing a neroli-type profile dominated by linalool (42.8%), limonene (19.9%), and linalyl acetate (15.3%). The tested batch of DFEO exhibited broad-spectrum antimicrobial activity, with Gram-positive bacteria showing the highest susceptibility. In situ experiments in model food systems confirmed concentration-dependent antimicrobial effects, with inhibition values reaching up to 89.47%. The application of DFEO in combination with vacuum packaging significantly improved the microbiological quality of fresh arugula during refrigerated storage (4°C, 14 days), reducing coliform bacteria by 1.26 log CFU/g compared with untreated controls. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis of culture-dependent bacterial isolates revealed a dominance of Pseudomonas spp., which are key contributors to spoilage of leafy vegetables. Although DFEO also demonstrated insecticidal activity against stored-product pests, its primary relevance lies in its antimicrobial efficacy in food systems. These findings demonstrate that DFEO has potential as a natural preservative for fresh produce, particularly when combined with vacuum packaging, contributing to improved microbiological quality of minimally processed vegetables during refrigerated storage.
