This study investigated the effects of chlorogenic acid (ChlA) applications on postharvest quality characteristics and biochemical components of sweet cherry (Prunus avium L. cv. ‘0900 Ziraat’) fruit. Fruits were treated with control, 0.5, 1.0, and 1.5 mM ChlA and stored at 4 ± 0.5 °C for 21 days. Storage significantly increased weight loss and decay rate while reducing respiration rate and biochemical quality. At the end of storage, the 1.5 mM ChlA treatment reduced weight loss from 8.32% in the control to 5.20% and decreased decay rate from 9.16% to 4.50%. ChlA applications also slowed changes in soluble solids content (SSC), titratable acidity (TA), and pH, contributing to a more stable chemical composition. The highest vitamin C content at the end of storage was recorded in the 1.5 mM ChlA treatment (11.71 mg 100 g⁻¹), compared with 9.97 mg 100 g⁻¹ in the control. Similarly, chlorogenic acid significantly delayed losses of organic acids and phenolic compounds; for example, quercetin content was maintained at 6.80 mg 100 g⁻¹ in 1.5 mM ChlA-treated fruit compared with 3.78 mg 100 g⁻¹ in the control after 21 days of storage. Principal component analysis (PCA) and correlation analysis revealed strong relationships among quality attributes and biochemical compounds and demonstrated the positive role of ChlA in preserving overall fruit quality. Overall, chlorogenic acid, particularly at 1.5 mM, effectively reduced postharvest quality losses and enhanced biochemical stability during cold storage.

Background: This study aims to investigate the effects of postharvest melatonin (ML) and salicylic acid (SA) applications on fruit quality and biochemical properties in tomatoes. The potential synergistic effects were investigated by applying these compounds to the ‘Depar’ tomato variety grown in Bolu in the 2024 production season. The tomato fruit that were mature and free from physical damage were selected and sterilized according to predetermined criteria. Afterwards, ML and SA solutions (1 mM) were sprayed on each fruit and then the fruit were stored at 5 ± 0.5 °C and 90 ± 5% relative humidity. Pomological and biochemical measurements and analyses were carried out on fruit stored for 24 days in three different periods (8th, 16th and 24th days). Results: With the extension of storage period, the increase in spoilage and ripening symptoms such as weight loss (8.53%), pH increase (5.01) and soluble solids content (SSC) accumulation (4.95%) was observed in tomatoes. In addition, the significant decreases occurred in malic acid, citric acid, tartaric acid, oxalic acid, vitamin C and phenolic compounds. However, SA and ML applications slowed down these negative changes, with the best results generally obtained in the SA + ML combination. This combination significantly limited the decreases in weight loss and chemical contents, delayed the ripening of tomatoes and maintained their nutritional value. Especially in early and middle storage periods (8th and 16th days of the cold storage), SA + ML applications gave the most effective results. However, some protective effects were reduced by the 24th day the cold storage. Conclusion: SA and ML applications are recommended as an effective biopreservation strategy to extend the shelf life of tomatoes, prevent commercial value loss and maintain quality. This study demonstrates the potential of using bioactive compounds to preserve the quality and nutritional values of tomatoes after harvest.
