“…Metabolomics is a powerful strategy for effectively identifying and quantifying metabolites within cells or tissues [16,17], providing an impartial approach for investigating correlations among interconnected metabolites via multiple pathways [18]. In recent years, metabolomics has been used to investigate the metabolic mechanisms underlying peach ripening and senescence [19]. The most commonly employed analytical techniques are liquid chromatography (LC)-tandem mass spectrometry (MS/MS) and nuclear magnetic resonance (NMR).…”

Peach fruit softening is the result of a series of complex physiological and biochemical reactions that influence shelf life and consumer acceptance; however, the precise mechanisms underlying softening remain unclear. We conducted a metabolomic study of the flesh and peel of the honey peach (Prunus persica L.) to identify critical metabolites before and after fruit softening. Compared to the pre-softening profiles, 155 peel metabolites and 91 flesh metabolites exhibited significant changes after softening (|log2(FC)| > 1; p < 0.05). These metabolites were mainly associated with carbohydrate metabolism, respiratory chain and energy metabolism (citrate cycle, pantothenate and CoA biosynthesis, nicotinate and nicotinamide metabolism, and pentose and glucuronate interconversions), reactive oxygen species (ROS) metabolism, amino acid metabolism, and pyrimidine metabolism. During peach fruit softening, energy supply, carbohydrate and amino acid metabolism, oxidative damage, and plant hormone metabolism were enhanced, whereas amino acid biosynthesis and cell growth declined. These findings contribute to our understanding of the complex mechanisms of postharvest fruit softening, and may assist breeding programs in improving peach fruit quality during storage.
