Comparative Characterization of Volatile Flavor Profiles and Key Markers in Early-, Mid-, and Late-Ripening Honey Peach (Prunus persica L. Batsch) Cultivars Using GC-IMS and HS-GC-MS.
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 evaluated the nonvolatile and volatile flavor profiles of six honey peach (Prunus persica L. Batsch) cultivars across early- ('Ri Chuan' and 'Jing Hong'), mid- ('Bai Feng' and 'Xia Hui'), and late-ripening ('Zhong Hu Jing'and'Wan Hu Jing') stages at comparable maturity. Late-ripening cultivars exhibited higher fruit weight, soluble solids content, and total sugars (95.34 vs72.01 mg/g in early cultivars). Although total acidity showed no significant group-level differences, organic acid compositions varied markedly: quinic and citric acids predominated in early cultivars, whereas malic acid was higher in mid- and late-ripening groups. Sucrose was the predominant sugar, while glucose, fructose, and sorbitol drove cultivar variation. GC-IMS and HS-GC-MS identified 51 and 71 volatile organic compounds (VOCs), respectively. Early-ripening cultivars were characterized by green/fatty aldehydes and ketones; mid-ripening cultivars by green-note alcohols and fruity esters; and late-ripening cultivars by terpenoids, lactones, and esters imparting floral, fruity, creamy, and ripe-peach aromas. Integrating VIP values, univariate testing, and odor-activity evaluation identified 12 key differential aroma-active markers (e.g., ethyl isobutyrate, hexyl acetate, nonanal, and γ-decalactone). Overall, peach flavor differentiation is governed by coordinated shifts in sugar-acid and volatile compositions, highlighting the complementary power of dual-platform profiling.
