“…Based on our existing research results, but more needs to be done to determine different indicators, such as antioxidant activity, total phenolics content, ascorbic acid, etc. (Khaliq et al, 2020), is needed to further analyze the possible mechanisms of maintaining quality changes in fruit treated with pullulan. Calcium chloride is known to influence the structural stability of the fruit tissue as well as enzyme activity and can significantly affect sugar metabolism with complex process.…”

In this study, the effects of postharvest treatment with 1% pullulan, 2% calcium chloride, and 1% chitosan on the physiological and biochemical properties, enzymatic activities and the differentially expressed genes (DEGs) with sucrose metabolism of Annona squamosa L. fruits stored at 15 ± 1°C for 12 days were investigated. Exogenous substances treatment retained a higher level of firmness, surface color, total soluble solids, organic acids, and tvolatile flavor substances compared to the control fruit. Exogenous substances treatments, particularly calcium chloride, enhanced sucrose phosphate synthase activity, whereas it inhibited acid invertase (AI) and neutral invertase (NI) activities. These changes in enzyme activities together resulted in a significantly higher sucrose content and lower glucose and fructose contents. The number (1550 genes), proportion (6.46%), and expression levels of DEGs in the calcium chloride‐treated fruit, which was enriched in the starch and sucrose metabolism pathways, were all significantly higher than in chitosan treatment. The findings indicated that exogenous calcium chloride might alter sucrose metabolism during fruit ripening by regulating the enzymatic activities and metabolism pathway. This will provide a theoretical basis for further research on the regulation of sugar metabolism by exogenous substances treatment to solve the problem of quality degradation in the storage of A. squamosa. Novelty impact statement This study indicated that the application of chitosan, pullulan, or calcium chloride, especially calcium chloride treatment, can effectively maintain the quality of Annona squamosa fruit during storage. It was found that exogenous calcium chloride might alter sucrose metabolism during fruit ripening by regulating the enzymatic activities and metabolism pathway. The results provided a theoretical basis for exploring the mechanism of exogenous substances for maintaining the postharvest quality and enhancing the shelf life of A. squamosa fruit in further research.

“…Retarded colour change of peel and higher TA and TSS contents of pulp were shown in the ripening process of NO-treated banana fruits [ 46 ]. SNP treatment retained higher levels of TA and ASA in postharvest apples [ 47 ]. NO could protect kiwifruits against oxidative damage by maintaining contents of vitamins C and E during cold storage [ 48 ].…”

“…SNP could markedly suppress the mycelial growth and spore germination of Colletotrichum gloeosporioides , resulting in delayed senescence in postharvest mango fruits [ 14 ]. NO treatment was a promising approach to improve resistance against fungal pathogens and maintain the quality of custard apples after harvest [ 47 ]. The resistance of pitaya fruit against anthracnose was also effectively enhanced by NO [ 54 ].…”

Nitric oxide (NO) acts as a gaseous signalling molecule and is considered to be a key regulator in the postharvest storage of fruits. Postharvest senescence is one of the most serious threats affecting the usage and economic value of fruits. Most recent studies have found that exogenous NO application can effectively improve the quality and prolong the shelf life of fruit postharvest by inhibiting postharvest diseases and alleviating chilling injury. Understanding the roles of NO is essential to elucidating how NO activates the appropriate set of responses to postharvest senescence. Here, we concluded that exogenous NO treatment alleviated senescence in postharvest fruit and attributed this to the following factors: (1) ethylene biosynthesis, (2) the antioxidant system, (3) polyamine metabolism and γ-aminobutyric acid (GABA) shunting, (4) cell wall metabolism, (5) sugar metabolism, (6) energy metabolism, (7) the CRT/DRE-binding factor (CBF) pathway and (8) S-nitrosylation. Moreover, crosstalk between NO and hydrogen sulfide (H2S), hydrogen peroxide (H2O2), oxalic acid (OA), arginine (Arg), GATA or plant hormone abscisic acid (ABA), melatonin (MT), and methyl jasmonate (MeJA), along with the regulation of key genes, were found to be very important in responses to postharvest senescence. In this study, we focus on the recent knowledge concerning the alleviative effect of NO on postharvest senescence, covering ethylene biosynthesis, the antioxidant system and related gene and protein expression.

“…Reactive oxygen species (ROS) can cause oxidative stress in the fruit, resulting in decreased sensory quality, leading to off flavors [3,6]. In order to maintain the quality and high contents of antioxidants and bioactive compounds, postharvest chemical treatments are commonly used by the fresh produce industry [6,7]. Treatments such as nitric oxide, 1-Methylcyclopropene and salicylic acid are some of the commonly used chemicals for preserving the antioxidants and overall quality of various horticultural produce [6][7][8].…”

The Effect of Gaseous Ozone and Moringa Leaf–Carboxymethyl Cellulose Edible Coating on Antioxidant Activity and Biochemical Properties of ‘Keitt’ Mango Fruit

This study evaluated the effect of edible coating and gaseous ozone on the antioxidant activities and biochemical properties of mango fruit. Mango fruit (cv. Keitt) were coated with moringa leaf extract and carboxymethyl cellulose (EC) before exposure to ozone (0.25 ppm). Gaseous ozone (O3) was administered intermittently for 24 or 36 h, and the control fruit were untreated. The fruit were stored at 10 °C for twenty-one days, then ripened at ambient temperature for seven days. The parameters measured were ascorbic acid, lipid peroxidation, phenolic content, total sugars, and antioxidant capacity (FRAP and DPPH). At the end of storage, the EC + O3 (36 h) had high phenolic content: 175.02 µg GEA/g DM compared to 151.87 µg GEA/g DM and 138.98 µg GEA/g DM for the O3 (24 h) and untreated fruit, respectively. Moreover, the combination of the EC and O3 (36 h) had a higher effect (p < 0.05) on preserving the antioxidant capacity of the mangoes. The EC + O3 (24 h) and EC significantly delayed fruit softening and maintained membrane integrity. Furthermore, the fruit treated with the EC reduced the accumulation of reducing (7.61 mg/mL) and total sugars (8.81 mg/mL) compared to the control treatment, which had a concentration of 12.74 mg/mL and 13.78 mg/mL, respectively. These findings demonstrate that EC combined with gaseous O3 enhanced the antioxidants of mango fruit during storage.
