“…24 Organic acids are considered the main substrates of the biogenesis of aromatic compounds, respiration and gluconeogenesis processes, and caused a decline in TA concentration. 9,27,33 The higher TA observed in hexanal-treated fruit as compared to control fruit might be due to the action of hexanal, which inhibits PLD activity and slows membrane phospholipid catabolism. Furthermore, the increase in TSS regardless of the treatment could be mainly a consequence of the breakdown of polysaccharides into soluble solids in the form of sugars, including fructose, sucrose and glucose.…”

“…It was reported that hexanal formulation as a postharvest spray showed no significant effects on flavonoid concentration in mango fruit stored at ambient and cold storage conditions. 27 CI occurred in persimmon fruit when it was stored below 8 °C and then transferred to ambient conditions, characterized by softening of the flesh, browning of the peel and a water-soaked appearance in the peel, rendering the fruit unmarketable. In the present study, exogenous hexanal application alleviated and delayed the CI symptoms of persimmon fruit, as indicated by the lower CI index and delayed color alteration (Table 4).…”

“…19 It is naturally emitted in the plant due to the disruption of tissues through lipid peroxidation-mediated pathways by the action of lipoxygenase and hydroperoxide lyase enzymes. 17 In recent years, the GRAS compound hexanal has been used effectively as a postharvest treatment for increasing shelf life, improving quality and reducing fruit loss of many climacteric and non-climacteric horticultural products such as guava, 20 banana, 21 tomato, 22,23 capsicum, 24,25 mango, [26][27][28] 29 sweet cherry, 30 carnation 31 and rose. 32 Also, its excellent performance as a preharvest treatment has been reported in several fruit and vegetable species in terms of suppressing ripening and senescence as well as maintaining quality in guava, 33 mango, [34][35][36] tomato, 37 nectarine 38 and apple.…”

BACKGROUNDPersimmon (Diospyros kaki L.) fruit is characterized by rapid metabolic changes following ripening, and softening occurs due to the gradual breakdown of the cell membrane by direct catabolic cascades of phospholipase D enzyme on the phospholipid bilayer. Cell membrane weakening is also enhanced by the generation of reactive oxygen species during stress conditions such as cold storage and postharvest handling. This research evaluated the postharvest hexanal dipping application on persimmon fruit storage quality.RESULTSThe response of ‘MKÜ Harbiye’ persimmon fruit to exogenous hexanal at different concentrations (0.04% and 0.08%, named as HEX‐I and HEX‐II, respectively) on quality parameters, chilling injury (CI), microbial growth, antioxidant compounds and free radical scavenging capacity (FRSC) during storage at 0 °C and 80–90 ± 5% relative humidity for 120 days were evaluated. Both hexanal treatments retained quality and delayed senescence, as indicated by greener peel (lower a* and L* values), higher firmness, total phenol concentration, FRSC and titratable acidity, but lower weight loss, electrical conductivity, rate of CO2, ethylene production, decay and microbial growth than the control. Total soluble solids were lower in treated fruit than the control up to 100 days, and were much lower in HEX‐I treatment as compared to HEX‐II treatment. HEX‐I treatment exhibited lower CI than the other treatments during storage.CONCLUSIONHexanal at 0.04% could be used to increase the storage period of ‘MKÜ Harbiye’ persimmon fruit up to 120 days at 0 °C and 80–90 ± 5% relative humidity by retaining quality and delaying senescence. © 2023 Society of Chemical Industry.

Blueberries are vulnerable to chilling injury (CI). This can lead to limited longevity when they are subjected to cold storage conditions. This study investigated the effectiveness of a preharvest spray containing 0.02% hexanal in reducing CI and improving the postharvest storage quality of ‘Star’ and ‘Biloxi’ blueberries. The blueberries were stored for a period of 5 weeks at 2 °C and in 90% relative humidity (RH). The findings revealed that the preharvest hexanal spraying of both cultivars delayed senescence by mitigating CI, as evidenced by the bolstering of the antioxidant defense system through increased superoxide dismutase (SOD), ascorbate peroxidase (APX), peroxidase (POD), catalase (CAT), and phenylalanine ammonia lyase (PAL) enzyme activity. The treated fruit also maintained elevated levels of total phenol content (TPC), total flavonoids (TFC), and vitamin C, demonstrating enhanced free radical scavenging capacity (FRSC), while exhibiting reduced polyphenoloxidase (PPO) activity, and reduced malondialdehyde (MDA), and H2O2 content in comparison with the control group. The preharvest hexanal treatment also suppressed fruit softening by maintaining greater firmness and higher membrane stability index (MSI) scores, inhibiting the activity of polygalacturonase (PG), pectinmethylesterase (PME), xylanase, and α‐amylase, and reducing microbial counts (MC) and incidence of decay (DI) in comparison with the control. Preharvest hexanal treatment also improved the overall storage quality by reducing weight loss, total soluble solids (TSS), pH, and the TSS/acid ratio, while increasing titratable acidity (TA) in comparison with the control during cold storage. The findings suggest that hexanal, as a preharvest application, delays senescence effectively and preserves overall quality by enhancing cold tolerance through antioxidant defense mechanisms in blueberry storage under cold conditions. © 2024 The Author(s).
