Special Issue Information

Dear Colleagues,

Recent academic research on "Postharvest storage and preservation of fruits and vegetables" covers a number of important topics and related areas.

Improvements in storage technologies and methods: Researchers are exploring a variety of innovative storage technologies and methods, including controlled atmosphere storage, temperature management, packaging technology, ethylene removal, and chemical treatments, to extend the storage life of fruits and vegetables.

Reduction of quality and nutrient losses: Research focuses on reducing the weight loss, spoilage, and nutrient loss of fruits and vegetables during storage and transportation, through appropriate storage conditions and handling methods.

Understanding of biological and physiological mechanisms: Scientists are studying the biological and physiological mechanisms of fruits and vegetables during storage, including respiration rate, ethylene production, and sensing, cell wall breakdown, enzyme activity, etc., to reveal their impact on storage life and quality.

Application of new technologies: Emerging technologies such as non-destructive testing, genetic improvement, and gene editing are being applied to improve the storage and preservation effects of fruits and vegetables, and to reduce the impact on the environment.

Research on post-storage treatment technology: Researchers are also paying attention to the development of post-storage treatment technology, such as post-storage treatment in a controlled atmosphere, chemical treatment, heat treatment, and ultraviolet treatment, to further extend the storage life of the product and maintain its quality.

These research topics cover a wide range from basic science to applied technology, helping to improve the later storage and preservation of fruits and vegetables and ensuring the safety and sustainability of the food supply.

Grapes are susceptible to mold and decay during postharvest storage, and developing new technologies to extend their storage period has important application value. Photodynamic technology (PDT) in concurrence with carbon dots (CDs) proposes an innovative and eco-friendly preservation strategy. We examined the effects of carbon dots combined with photodynamic treatment on postharvest senescence and antioxidant system of table grape. The compounding of photodynamic technology with a 0.06 g L−1 CDs solution could possibly extend the postharvest storage period of grape berries. Through this strategy, we achieved a decreased rate of fruit rotting and weight loss alongside the delayed deterioration of fruit firmness, soluble solids, and titratable acid. As paired with photodynamic technology, CDs considerably decreased the postharvest storage loss of phenols, flavonoids, and reducing sugars as compared to the control group. Concurrently, it remarkably postponed the build-up of hydrogen peroxide (H2O2), superoxide anion (O2∙−), and malondialdehyde (MDA); elevated the levels of reduced ascorbic acid (AsA) and reduced glutathione (GSH); lowered the levels of dehydroascorbic acid (DHA) and oxidized glutathione (GSSG); raised the ratios of AsA/DHA and GSSH/GSSG; encouraged the activities of superoxide dismutase (SOD) and phenylalanine ammonia-lyase (PAL); and inhibited the activities of polyphenol oxidase (PPO) and lipoxygenase (LOX). Furthermore, it enhanced the iron reduction antioxidant capacity (FRAP) and DPPH radical scavenging capacity of grape berries. CDs combined with photodynamic treatment could efficiently lessen postharvest senescence and decay of grape berry while extending the storage time. Full article
