Special Issue Information

Dear Colleagues,

The first and second editions of this Special Issue were incredibly successful. (https://www.mdpi.com/journal/foods/special_issues/IA8UA14903; https://www.mdpi.com/journal/foods/special_issues/VFLS3GX0U1). We would like to express our gratitude to everyone who contributed to these Special Issues for their participation and support.

Fresh fruit and vegetables are a dietary source of vitamins, minerals, and dietary fiber, but, due to their short postharvest life, a large portion of the produce is lost. It is therefore necessary to investigate the biological changes underlying ripening and senescence and find ways to control the perishability of fresh fruit and vegetables, thereby increasing their shelf life. The basic science of the ripening and senescence of these foods has progressed rapidly in recent years, largely due to a series of breakthrough discoveries that have uncovered some of the key factors and signaling pathways by which ripening- and senescence-associated genes have been set into motion. On the other hand, advanced postharvest technologies, including chemical treatment, physical methods, and biotechnology, have been widely applied to minimize postharvest loss and maintain commercial quality. The aim of this Special Issue is to gather pioneering research on the biological mechanisms of, and preservation technology for, fresh fruit and vegetables. All aspects of postharvest research throughout the supply chain will be considered, such as technologies, underpinning mechanisms, and quality evaluation.

Postharvest Hupingzao jujubes are prone to softening and reddening during storage. To investigate the influence of glycine betaine on the fruit quality of cold-stored jujubes, the jujubes were immersed in a 15 mmol L−1 glycine betaine solution for 10 min, then stored at 0 ± 1 °C for 100 days. The relevant physical and chemical quality indicators were determined every 20 days. The results indicated that glycine betaine treatment effectively maintained fruit firmness, reduced weight loss, slowed down the respiration rate, and lessened the redness of the fruit peel. Compared with the control group, the malondialdehyde and H2O2 contents in glycine betaine-treated fruit decreased by 26.65% and 9.04%, respectively. In addition, glycine betaine treatment elevated the contents of non-enzymatic antioxidants, including ascorbic acid, total flavonoids, total phenols, and proanthocyanidins. Meanwhile, the activities of superoxide dismutase, peroxidase, catalase, and ascorbate peroxidase in the jujube fruit were enhanced after glycine betaine treatment. In conclusion, glycine betaine treatment preserved the quality of the jujube fruits by enhancing the antioxidant metabolism. The results establish a scientific basis for the potential application of glycine betaine in postharvest fruit preservation, providing a strategy to mitigate storage-related quality deterioration.
