Resumen :
El fruto de tomate (Solanum lycopersicum L.) es un fruto perecedero que posee un almacenamiento limitado debido a que es susceptible a daños por frío cuando se conserva en condiciones de refrigeración, las cuales se emplean para retrasar la maduración. Por esta razón, en este estudio se probaron di... Ver más
The tomato fruit (Solanum lycopersicum L.) is a perishable fruit with limited storage capacity due to its susceptibility to chilling injury when stored under refrigeration conditions, which are commonly used to delay ripening. For this reason, in this study, different concentrations (10, 50, and 100 mg L⁻¹) of chlorogenic acid (CGA) were tested to evaluate its effectiveness in maintaining fruit quality characteristics and mitigating symptoms of chilling injury in tomatoes. Our results showed that CGA treatments effectively delayed weight loss and maintained fruit firmness, with the best results observed at a dose of 50 mg L⁻¹. In general, higher concentrations did not lead to significant improvements in quality. Additionally, CGA-treated tomatoes exhibited reduced malondialdehyde (MDA) content and electrolyte leakage (EL), indicating improved membrane integrity and reduced oxidative damage. CGA treatments maintained a higher total phenolic content during storage, with significant levels of individual polyphenols such as rutin, neochlorogenic acid, and p-coumaric acid, suggesting enhanced antioxidant capacity and better preservation of fruit quality. This is the first time that CGA's potential to reduce the impact of chilling injury has been evaluated in any fruit species, and its impact on tomato ripening demonstrates its ability to preserve fruit quality during cold storage, thereby extending its shelf life. Notably, we highlight its natural origin and effectiveness as a postharvest treatment.
