Fluorescent carbon dots (CDs) have been widely studied in biosensing, imaging, information encryption, and optoelectronic devices due to excellent optical properties, such as photostability, tunable luminescence range, and resistance to photobleaching. In recent years, CDs have been explored for use in agriculture. Based on their light harvest and light conversion capacity, as well as their characteristics of easy synthesis and low toxicity, CDs show great potential in improving crop photosynthesis.In addition, CDs can also be used for smart and anticounterfeiting packing, food safety detection, and preservation of crops after harvest. In this study, the application of CDs with excellent optical properties in crops has been summarized, including preharvest processes (photosynthesis and plant imaging), and postharvest processes (crop preservation and food safety).Then the toxicity of CDs to crops is introduced. Finally, the present challenges and future prospects are discussed.

“…The results showed that water in apple slices migrated from vacuoles to cytoplasm with the prolongation of storage time, and high‐density water appeared at the edge of the slices during the late storage period. Similarly, the spatial distribution of water in fresh‐cut cucumber (Fan et al., 2021), fresh‐cut honeydew melon (Jiang et al., 2022), fresh‐cut eggplant (Wu et al., 2021) and fresh‐cut broccoli (Xu et al., 2017) was presented by MR weighted images.…”

Fresh-cut fruits and vegetables are healthy and convenient ready-to-eat foods, and the final quality is related to the raw materials and each step of the cutting unit. It is necessary to integrate suitable intelligent detection technologies into the production chain so as to inspect each operation to ensure high product quality. In this paper, several imaging technologies that can be applied online to the processing of fresh-cut products are reviewed, including: multispectral/hyperspectral imaging (M/HSI), fluorescence imaging (FI), X-ray imaging (XRI), ultrasonic imaging, thermal imaging (TI), magnetic resonance imaging (MRI), terahertz imaging, and microwave imaging (MWI). The principles, advantages, and limitations of these imaging technologies are critically summarized. The potential applications of these technologies in online quality control and detection during the fresh-cut processing are comprehensively discussed, including quality of raw materials, contamination of cutting equipment, foreign bodies mixed in the processing, browning and microorganisms of the cutting surface, quality/shelf-life evaluation, and so on. Finally, the challenges and future application prospects of imaging technology in industrialization are presented.

“…during processing, transportation, and storage, accounts for the vast majority of the global food wastage every year, − which is thus maximally related to major global challenges such as famine and public health emergency, , especially in economically backward countries and regions. , It is therefore that a simple, low-cost, universal, and sustainable preservation technique is urgently needed. Existing preservation techniques for perishable foods mainly include preservative addition, wax coating, irradiation, cold storage, heat treatment, and modified atmosphere packaging (MAP). − Compared with other preservation techniques, MAP has received more attention because of its security, effectiveness, and persistence. , MAP usually works in two basic modes: active and passive. Active MAP mainly depends on initial gas flushing or the introduction of a gas scavenging system within the package to accelerate gas composition modification.…”

To reduce poverty and hunger in economically backward countries and regions, increasing demand for addressing severe worldwide food deterioration and wastage has triggered intensive research efforts toward modified atmosphere packaging (MAP) technology. Herein, we demonstrate that natural lignin can be used as a cheap and green monomer for preparation of hydrogen-bonded covalent organic polymers (HCOPs) with good crystallinity, permanent porosity, and high thermostability. The optimal lignin-based HCOPs (named LT-HCOPs) are synthesized by using tetrafluoroterephthalonitrile as the cross-linker, ethanol/water (7/3, v/v) as the reaction solvent, 120 °C as the reaction temperature, and ammonium persulphate and anhydrous potassium carbonate as catalysts. As-prepared LT-HCOPs can be used as promising "switches" for regulating gas permeability in the passive MAP membranes. The LT-HCOP-based passive MAP membrane, which is prepared by a simple mixing and solvent evaporation process, shows good biocompatibility, antimicrobial and antioxidant activities, improved ultraviolet light barrier property, high CO 2 /O 2 selectivity, and suitable H 2 O permeation and thus is demonstrated to work well in prolonging the shelf life of perishable foods such as strawberries, waxberries, cherries, cherry tomatoes, and mangoes. This work provides a feasible way to use cheap and green natural materials to construct advanced functional materials for practical applications.
