This perspective aims to establish an integrated framework for understanding postharvest physiology and guiding sustainable quality preservation strategies. Deterioration is driven by complex molecular and physiological transformations, including ripening, senescence, and oxidative stress. Understanding these mechanisms is paramount for developing effective loss and waste reduction strategies. Metabolomics provides a systems level view of these changes, enabling the large scale profiling of small molecules and the identification of valuable biomarkers for quality loss, chilling injury, and senescence. Shifts in primary metabolites (sugars, organic acids) and the accumulation of \u2018off aroma\u2019 volatiles (ethanol, acetaldehyde) are critical indicators of decline. Also, preharvest factors (e.g. regulated deficit irrigation, signalling molecule application) fundamentally influence postharvest metabolic states by enhancing antioxidant capacity and delaying senescence. Molecular regulation, orchestrated by hormonal signalling (ethylene, abscisic acid) and transcription factors, underpins these shifts. Interventions focus on sustained redox homeostasis, often achieved through the exogenous application of ecofriendly signalling molecules like salicylic acid to upregulate enzymatic and non-enzymatic antioxidant systems. Integrating multi-omics technologies (metabolomics, transcriptomics) facilitates the identification of molecular targets for these interventions and supports predictive modelling for optimising storage conditions. Translating these integrated insights into sustainable, biomarker based, farm to fork strategies is essential for enhancing food security and mitigating global greenhouse gas emissions associated with food loss.<\/jats:p>","DOI":"10.3389\/fpls.2026.1763497","type":"journal-article","created":{"date-parts":[[2026,2,6]],"date-time":"2026-02-06T06:55:54Z","timestamp":1770360954000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["A systems level framework for postharvest physiology and quality preservation"],"prefix":"10.3389","volume":"17","author":[{"given":"Mar\u00eda E.","family":"Garc\u00eda-Pastor","sequence":"first","affiliation":[{"name":"Department of Applied Biology, Institute for Agri-Food and Agro-Environmental Research and Innovation (CIAGRO), University Miguel Hern\u00e1ndez","place":["Alicante, Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia","family":"Falag\u00e1n","sequence":"additional","affiliation":[{"name":"Plant Science Laboratory, Cranfield University","place":["Cranfield, United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/j.postharvbio.2025.113610","article-title":"Induction of fresh produce defense response: Mechanism, challenges, and future directions","volume":"227","author":"Chowdhary","year":"2025","journal-title":"Postharvest Biol.
