“…Jia et al [42] indicated that softening of jujube fruit could be delayed by delaying the degradation of protopectin. In addition, a study also found that slowing down the decomposition of original pectin in 'Kyoho' grape maintained its firmness and slowed down the increase in soluble pectin content [43]. A similar conclusion was found when red raspberries were treated with calcium chloride [44].…”

Cold plasma (CP) is a green and efficient preservation technology, but its effect on preventing the postharvest softening of fruits and vegetables is still unclear, and the effects of different CP intensities on the postharvest softening of winter jujubes (Ziziphus jujuba Mill. cv. Dongzao) have been little studied. In this study, we investigated the effects of different CP intensities (0 kV, 40 kV, and 80 kV) on the postharvest storage quality of winter jujubes and the activities of key enzymes related to softening during storage. The results showed that compared with the control group, the contents of firmness, total soluble solids (TSS), titratable acidity (TA), and vitamin C (VC) in the CP treatment group were higher and the respiratory intensity and weight loss rate were lower. In addition, CP treatment can also inhibit the degradation of protopectin and cellulose and the accumulation of soluble pectin. Moreover, CP treatment inhibited the activities of polygalacturonase (PG), pectin methyl esterase (PME), 3α-L-arabinoside (α-L-Af), 4β-galactosidase (β-gal), cellulase (Cx), and β-glucosidase (β-Glu). This shows that CP treatment has a positive effect on the preservation of winter jujubes, and the preservation effect of the 80 kV treatment was better than that of the 40 kV treatment. This provides a certain basis for cold plasma treatment in the preservation of winter jujubes.

SummaryGrape is widely consumed all over the world for its rich nutritious and health‐promoting effects. While grape berries are prone to quality deterioration after harvest. This study aimed to investigate the effect of eugenol treatment on the quality of grape berries based on the transcriptome. Harvested grape berries were treated with eugenol, and then collected for nutrient component determination and transcriptomics analyses. As a results, treatment with eugenol enhanced the berries firmness, increased the contents of soluble sugars, organic acids and phenolic compounds, improved the antioxidant capacity, and altered gene expression levels of related pathways. Transcriptome analysis revealed 699 differentially expressed genes by 100 mmol L−1 eugenol‐treated berries. Among these DEGs, the transcriptional levels involved in the cell wall, sugar and acid metabolism, phenylpropane metabolism, antioxidant enzymes, and WRKY, MYB family transcription factors were significantly regulated. This study will help to promote the application of eugenol for quality improvements in grape berries.

“…This suggests a lower content of hypotaurine and γ-aminobutyric acid in packaged apples, both of which have been reported to alleviate excess reactive oxygen species and activate antioxidant enzymes. Therefore, the above findings also indicate that fresh-cut apples under multilayer nanopackaging are less susceptible to oxidative stress and cellular damage. − This effect is particularly evident in the (CMC/SA) 19 @GO 5 packaging, which is characterized by excellent oxygen barrier properties.…”

Considering the ecological and environmental issues caused by petroleum-based plastics for packaging fresh-cut fruits and vegetables (FFVs), there is an urgent need to develop sustainable and ecofriendly active packaging. Therefore, marine-derived biodegradable carboxymethyl chitosan (CMC) and sodium alginate (SA) were used to construct a layer-by-layer assembly system. Then, graphene oxide (GO) was introduced into the SA layer to produce (CMC/SA) n @GO x composite films. The impacts of the GO content (x) and assembly layers (n) were investigated on the internal interactions, microstructure, and packaging properties of the multilayer films. The rise of x and n leads to the increase of the microregion size and interface thickness in the films, and the introduction of GO into the SA layer enhanced its attraction to the CMC layer. With variations in both x and n, the (CMC/SA)19@GO5 film exhibited the greatest mechanical and barrier properties, along with enhanced UV-shielding capacity. Based on the above result, three different (CMC/SA) n @GO x films were selected for fresh-cut apple packaging, with transcriptomics used to investigate preservation mechanisms. The results showed that the (CMC/SA)19@GO5 packaging performed with the best physiological quality due to its high barrier properties, resulting in lower weight loss, reduced browning, and improved hardness. This was attributed to enhanced antioxidant capacity and resistance to wounding stress as well as delayed cell wall degradation and terpenoid biosynthesis, extending the shelf life of fresh-cut apples. In conclusion, this study demonstrated the potential of green packaging based on marine biopolymers for FFV preservation.
