Summary: The use of fresh basil is becoming increasingly popular due to its unique aromatic and sensory properties. However, fresh basil has a short shelf life and is highly sensitive to chilling, resulting in leaf browning and loss of aroma. Moderate CO2 atmospheres have shown potential in alleviating chilling injury symptoms, but their effect on flavor volatiles and the impact of chilling temperatures on basil volatile profile are unclear. This study investigated how two basil genotypes responded to low temperatures and atmosphere modification, focusing on the volatile organic compounds responsible for basil aroma and flavor. It was found that chilling injury and loss of aroma volatiles were more severe at 5°C compared to 10°C and 15°C, and storage in 5% CO2 ameliorated chilling injury symptoms in one genotype but not in the other. Both chilling temperatures and controlled atmospheres affected key volatile compounds related to basil aroma and flavor, with temperature having a greater influence on the observed changes in volatile profile.

Summary: In this study, the effects of intermittent stepwise cooling and stepwise warming (ICW) on chilling injury (CI) in mango fruit were investigated. Results showed that ICW exposure maintained normal ripening in mango fruit during refrigeration and shelf storage. ICW inhibited electrolyte leakage rate and production of reactive oxygen species and malondialdehyde. ICW also resulted in higher activities of antioxidant enzymes and more accumulation of phenolics, flavonoids, ascorbic acid, and glutathione. Additionally, the expression of cold-responsive genes was upregulated. These physiological and biochemical changes contributed to enhanced cold tolerance and reduced CI in mango fruit.

Summary: This study found that the use of controlled atmosphere (CA) treatment can alleviate chilling injury (CI) of peach fruit during cold storage, improving sensory quality. CA treatment increased the content of volatile esters and lactones in peach fruit during extended cold storage, which were positively correlated with consumer acceptability. Furthermore, CA treatment also led to higher sucrose content and degree of fatty acids unsaturation in peach fruit, providing insights into the mechanism of resistance to cold stress.

Summary: Transcriptome sequencing and HS-SPME-GC-MS analysis were used to study the differentially expressed genes and volatile organic compounds (VOCs) in spicy and non-spicy pepper fruits. The results showed that fatty acid biosynthesis and terpenoid biosynthesis may be the main metabolic pathways for aroma differences between these two types of fruits. The differential expression of genes related to fatty acid biosynthesis and key terpene synthesis genes may contribute to the different aroma. The findings provide references for the development of high-aroma pepper germplasm resources and breeding of new varieties.

Summary: Peaches are highly valued for their juicy flesh, delicious taste, and pleasant aroma. The formation of aroma volatiles in peaches is influenced by factors such as fruit development, genetic background, cultivation management, and post-harvest treatment. Although there have been advancements in understanding the biosynthetic pathways of fruit aroma, the regulatory mechanisms are still not well understood. Recent studies using molecular biology and multi-omics techniques have provided new insights into the molecular functions of peach genes, which can greatly contribute to enhancing fruit flavor and breeding programs.

Summary: This study aimed to compare the discrimination ability and detection limit of visible and short-wave near-infrared hyperspectral imaging features and spectral information on early implicit bruised pears. Physical characteristics were more sensitive than chemical parameters for bruised pears during postharvest storage. The changes in spectral variations at specific wavelengths could explain the bruising changes in pears. Discrimination models based on selected spectral variables could effectively identify bruised pear areas, and the combination of imaging features and spectral variables achieved higher discrimination rates.

Summary: This study found that H2S treatment can delay the senescence process of postharvest pakchoi by regulating antioxidant system, endogenous H2S and NO metabolism. H2S increased the activities of antioxidant enzymes by up-regulating the expression of enzyme genes, reducing the accumulation of harmful substances. Furthermore, H2S increased the content of cysteine and nitrate in pakchoi by regulating the expression of related genes and enzyme activities, thus slowing down the senescence of pakchoi.
