“…Similar results have been observed in pomegranate fruit, where CI was accompanied by higher EL and MDA levels, higher ROS accumulation, and higher activity of the membrane‐degrading enzymes PLD and LOX . Liu et al . also showed that melatonin treatment delayed strawberry senescence and lowered MDA accumulation.…”

BACKGROUND Sapota is a popular tropical fruit characterized by a very short postharvest life. Low‐temperature storage prolongs postharvest life of sapota fruit, but chilling injury symptoms can develop if the storage temperature is less than 14 °C. There have been no reports on the effects of postharvest melatonin application on the development of chilling injury in sapota fruit during cold storage. The objective of this study was to investigate the effects of different concentrations of postharvest melatonin application (0, 30, 60 and 90 μmol L−1) during cold storage (8 °C) for up to 30 days with an additional 1‐day shelf life at ambient temperature. RESULTS All melatonin treatments reduced chilling injury symptoms, reduced electrolyte leakage, malondialdehyde (MDA) content, H2O2 and superoxide anion (O2−), and increased proline content and the activity of superoxide dismutase (SOD), catalase (CAT) and γ‐aminobutyric acid (GABA), and reduced the activities of phospholipase D (PLD) and lipoxygenase (LOX) compared to the control. CONCLUSION Postharvest melatonin treatment could be a useful strategy for reducing chilling injury during cold storage and transport of sapota fruit. The results indicate that melatonin reduces chilling injury of sapota fruit through maintaining membrane integrity, SOD and CAT activities, and reducing PLD and LOX activities. © 2019 Society of Chemical Industry

“…Our results for antioxidant capacity were in the range of data reported in the literature by both DPPH and ABTS methodologies for many strawberry cultivars . Similar tendencies for antioxidant capacity have been reported in untreated fruit from other strawberry cultivars . Changes in DPPH were highly correlated with those of total anthocyanin and total phenolic content (Pearsonʼs correlation coefficient: r = 0.941 and 0.890, respectively, in strawberries treated with 9 g L −1 POS).…”

“…Our results suggest that the observed firmness retention as an effect of 9 g L −1 POS treatment was not related to coating formation on the strawberry surface. Recently, there have been reports of postharvest treatments with no surface coatings that significantly decreased the weight loss of treated strawberry fruit, including alginate oligosaccharides, melatonin, methyl jasmonate, and vaporized ethyl pyruvate …”

Postharvest application of pectic‐oligosaccharides on quality attributes, activities of defense‐related enzymes, and anthocyanin accumulation in strawberry

et al. 2020

BACKGROUND The postharvest application of pectic‐oligosaccharides (POS) as an elicitor to improve the postharvest shelf‐life and nutritional quality by stimulating natural defense mechanisms in strawberries was studied. Strawberries (cv. Festival) were treated with POS (at 0, 2, 5, and 9 g L−1) and evaluated for firmness, weight loss, color, soluble solids, titratable acidity (TA), total phenolic and anthocyanin content, antioxidant capacity, decay, and some defense‐related enzyme activity during storage at 2 ± 0.5 °C for 14 days. RESULTS Treatment with POS significantly delayed (P < 0.05) strawberry decay, and reduced the water loss and softening of fruit during storage. Strawberries treated with POS showed a significant increase in total phenolic and anthocyanin content, and antioxidant capacity when compared with controls. Interestingly, POS induced higher activity of phenylalanine ammonia‐lyase (PAL), chitinase, and β‐1,3‐glucanase in strawberries. Compared to the control, the activity of enzymes was markedly increased in fruit treated with all tested POS concentrations, particularly chitinase, and β‐1,3‐glucanase activities, but 5 and 9 g L−1 POS were the most effective treatments for maintaining the quality attributes and improving anthocyanin accumulation and antioxidant capacity of strawberries. CONCLUSION These findings suggest that POS treatment could potentially be applied to maintain quality attributes, reduce decay, and further enrich the anthocyanin content and antioxidant capacity of strawberries during postharvest storage. The results also suggest that the positive effects of POS on strawberries could be associated with the rapid accumulation of chitinase and β‐1,3‐glucanase activities, and the increase of PAL enzyme activity leading to the synthesis and accumulation of anthocyanins. © 2019 Society of Chemical Industry

“…In this study, among all the treatments, AC1.2 (the combination of 100 mg L −1 AsA and 1.2 mmol L −1 ceramide) was effective in delaying the color change, keeping SSC and reducing weight‐loss and decay index of strawberries during storage, exhibited the positive roles of the combination of AsA and ceramide on preserving the quality of strawberries. Similar results were obtained in strawberry fruit treated with melatonin . Compared with the treatment with AsA or ceramide alone, the combination of AsA and ceramide greatly increased the activities of antioxidant enzymes in strawberries, but inhibited the increase in the contents of ROS, MDA, and proline.…”

Synergistic effects of ascorbic acid and plant‐derived ceramide to enhance storability and boost antioxidant systems of postharvest strawberries

et al. 2019

BACKGROUND Excessive reactive oxygen species (ROS) may attack biological macromolecules and induce oxidative stress. The inhibition by ascorbic acid (AsA) on oxidative damage has been reported in fruits, while the barrier effect of ceramide has also been proven. However, there are few reports about the effects of ceramide–AsA interactions to enhance storability and boost antioxidant systems in fruits during storage. This study was conducted to study the synergistic effects of AsA in combination with ceramide on the quality of postharvest strawberry (Fragaria anannasa cv. Tianbao). RESULTS Treatment with 100 mg L−1 AsA plus 1.2 mmol L−1 ceramide significantly delayed the rot of strawberries, reduced the water loss and the contents of ROS, malonaldehyde (MDA), and proline, however, increased the contents of total flavonoids, total phenols, and anthocyanins compared with other treatments. Also, treatment with 100 mg L−1 AsA plus 1.2 mmol L−1 ceramide significantly increased the activities of peroxidase (POD) and superoxide dismutase (SOD) but inhibited the activity of polyphenol oxidase (PPO). CONCLUSION It is suggested that treatment with 100 mg L−1 AsA plus 1.2 mmol L−1 ceramide could significantly reduce the oxidative damage and maintain the storage quality of strawberries during storage by enhancing the antioxidant systems. © 2019 Society of Chemical Industry
