This study evaluated the postharvest evolution in terms of quality and functional traits recently introduced mini plum tomato cultivars, differing for fruit pigmentation. The cultivars Santy Naranja (orange fruit) Melange (dark red, green-striped fruit), along with well-established ‘Angelle’ (red were monitored during refrigerated storage (10 °C) 0, 7, 14 days (hereafter S0, S7, S14, respectively) inside closed polylactic acid trays. ‘Melange’ displayed highest fresh weight loss total soluble solids (TSS) (9.28 °Bx), lowest firmness (4.69 N), whereas ‘Santy Naranja’ showed strongest color deviation period. Titratable acidity (TA) was relatively stable ‘Melange’, while experienced decrease between S7 resulting stronger TSS/TA fluctuations. Regarding traits, had polyphenols content (TPC), excelled carotenoid (TCC), ascorbic (AsA), fruits’ antioxidant activity, as revealed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) ferric reducing power (FRAP) assays. With reference to time, O2 concentration headspace, TPC, AsA, DPPH decreased S0 CO2 concentration, TCC, FRAP increased, but these variations mostly cultivar-dependent. provides insights into behavior novel typologies their ability maintain over providing information developing strategies preserve sensory nutraceutical characteristics storage.

ABSTRACT The senescence of leafy vegetables is inherent and general after harvest. DNA methylation affects the process plant leaves. Limited studies have explored impact exogenous inhibitors on postharvest mechanisms their effects transcriptome metabolome during storage. In this study, pak choi was immersed in 100 mg L −1 5‐azacytidine (AZ) (an inhibitor methyltransferase) solutions, indicated that AZ yielded significant acceleration leaf senescence. Compared to control group, AZ‐treated exhibited faster weight loss, higher malondialdehyde content, greater color change, chlorophyllase activity. Transcriptomic widely targeted metabolomic analyses were then performed samples. investigation disclosed chlorophyll degradation genes BraSGR2 BraPPH upregulated by AZ, leading more content. effectively stimulated upregulation senescence‐associated ( BraSAG20 , BraSAG21 BraSRG1 BraSRG2 ), thereby accelerating pace process. demonstrated downregulated flavonoid synthase BraFLS1 BraF3H causing a relative decline levels. study also unveiled diminution carbohydrate content storage, further exacerbated AZ. To encapsulate, our preliminary findings suggest application accelerates stored choi, which helps us understand relationship between demethylation vegetable
