“…For instance, AsA, an antioxidant, can maintain the postharvest firmness of fruit ( Sogvar, Koushesh Saba & Emamifar, 2016 ). In a previous study, 100 mM of GSH decreased the firmness of strawberry fruit, which was not significantly different from the control ( Ge et al, 2019 ). This might be due to low metabolic activities and reduced respiration rates caused by GSH coating; thus, the pH remained unchanged.…”

“…GSH provides a barrier by creating a semipermeable layer on the fruit surface to reduce transpiration losses. In tomatoes ( Zhou et al, 2022b ) and strawberries ( Ge et al, 2019 ), GSH acts as a barrier against water loss to reduce weight loss. The present study results confirmed that the treatment with 5 mM GSH could significantly prevent weight loss in mangoes.…”

“…Glutathione (GSH), a potent antioxidant, is an essential component of the ascorbate-glutathione (AsA-GSH) pathway of plant cells that scavenges ROS and protects the plant against oxidative damage ( Hasanuzzaman, Hossain & Fujita, 2011 ; Nahar et al, 2015 ). The application of GSH to strawberry fruit could increase its endogenous antioxidant content and antioxidant capacity ( Ge et al, 2019 ). In tomato seedlings, GSH treatment could induce antioxidant generation and activate the AsA-GSH cycle to alleviate oxidative damage and improve the salt stress response ( Zhou et al, 2017 ).…”

Background Mango fruit is prone to decay after harvest and premature senescence, which significantly lowers its quality and commercial value. Methods The mango fruit (Mangifera indica L.cv. Guixiang) was treated with 0 (control), 2, 5, and 8 mM of reduced glutathione (GSH) after harvest. The fruit was stored at 25 ± 1 °C for 12 days to observe the changes in the antioxidant capacity and postharvest quality. Results Compared with the control, the 5 mM GSH treatment significantly decreased the weight loss by 44.0% and 24.4%, total soluble solids content by 25.1% and 4.5%, and soluble sugar content by 19.0% and 27.0%. Conversely, the 5 mM GSH treatment increased the firmness by 25.9% and 30.7% on days 4 and 8, respectively, and the titratable acidity content by 115.1% on day 8. Additionally, the 5 mM GSH treatment decreased the malondialdehyde and hydrogen peroxide contents and improved the antioxidant capacity of mango fruit by increasing the superoxide dismutase and peroxidase activities and upregulating the expression of the encoding genes. Meanwhile, the higher levels of monodehydroascorbate reductase, dehydroascorbate reductase, and glutathione reductase enzyme activities and gene expressions accelerated the AsA-GSH cycle, thereby increasing the accumulation of AsA and GSH and maintaining the redox balance. Conclusions Overall, the experimental results suggest that 5 mM GSH maintains high antioxidant capacity and postharvest quality of mangoes and can use as an effective preservation technique for postharvest mangoes.
