“…Meanwhile, physical processing technology was also introduced into the research field. Chitosan/thyme oil coating combined with UV-C (short wave ultraviolet irradiation) treatment was adopted to inhibit the activity of polygalacturonase, pectin methylesterase, cellulose and β-glucosidase by controlling the expression intensity of related enzyme genes and reducing the loss of polysaccharides in the blueberry cell wall, thus maintaining the integrity of blueberry cell wall tissue structure and inhibiting the postharvest softening and senescence of blueberries [8].…”

The postharvest softening and corresponding quality deterioration of blueberry fruits are crucial factors that hinder long-distance sales and long-term storage. Cold plasma (CP) is an effective technology to solve this, but the specific mechanism of delaying fruit softening remains to be revealed. Here, this study found that CP significantly improved blueberry hardness. Physiological analysis showed that CP regulated the dynamic balance of reactive oxygen species (ROS) to maintain hardness by increasing antioxidant content and antioxidant enzyme activity, resulting in a 12.1% decrease in the H2O2 content. Transcriptome analysis revealed that CP inhibited the expression of cell wall degradation-related genes such as the pectin hydrolase gene and cellulase gene, but up-regulated the genes of the ROS-scavenging system. In addition, the resistance genes in the MAPK signaling pathway were also activated by CP in response to fruit ripening and softening and exhibited positive response characteristics. These results indicate that CP can effectively regulate the physiological characteristics of blueberries at a genetic level and delay the softening process, which is of great significance to the storage of blueberries.

During postharvest storage, the metabolism of cell wall components greatly affects the quality of fruits and vegetables. Utilizing 1‐methylcyclopropene (1‐MCP) as an ethylene receptor inhibitor and modified atmosphere (MA) separately or in combination (1‐MCP+MA) were investigated for their impact on Zizania latifolia quality during postharvest storage. The treatments effectively controlled firmness increase, color degradation, and reductions in soluble protein, reducing sugar, total phenol, and ascorbic acid content, with the combined 1‐MCP+MA showing the most significant effect. These treatments also moderately changed soluble pectin, protopectin, cellulose, and hemicellulose content, preserving the activities of essential enzymes and the expression of enzyme genes. The combined treatment particularly demonstrated superior preservation capabilities, holding promise for reducing postharvest losses and maintain the storage quality of edible produce, offering insights for efficient postharvest storage and freshness maintenance of fruits and vegetables.
