Abstract The detection of total antioxidant capacity (TAC) in teas and its vital indicator for monitoring the fermentation degree during black tea processing are great significance intelligent manufacturing industry. Here, highly dispersed manganese species on Co‐MOF with hollow structures (HS‐Mn/Co‐MOF) nanozyme superior oxidase‐like activity is constructed colorimetric ascorbic acid (AA) TAC. Owing to Mn doping unique structures, HS‐Mn/Co‐MOF possesses more surface active oxygen species, negative charges rapid mass transport, thus resulting 20‐times higher catalytic 30‐times reaction rate than that pure Co‐MOF. Thanks remarkable activity, nanozyme‐based sensor exhibits a wide linear range 0.01–120 µ m , along low limit 3 n AA detection. Additionally, determination TAC levels real samples further achieved different types can be effectively distinguished by utilizing nanozyme. Identification prediction quality process using combined machine learning realized first time.

During the transportation and storage of food, foodborne spoilage caused by bacterial biofilm infection is prone to occur, leading issues such as short shelf life, economic loss, sensory quality instability. Therefore, development novel efficient antibacterial agents capable efficiently inhibiting bacteria throughout various stages food processing, transportation, strongly recommended researchers. The emergence nanozymes considered be an effective candidate for in industry. As potent agents, have advantages low cost, high stability, strong broad-spectrum ability, biocompatibility. Herein, we aim summarize classification status nanozymes. Furthermore, general catalytic bacteriostatic mechanism against intracellular bacteria, planktonic activities are highlighted, mainly concerning destruction cell walls and/or membranes, reactive oxygen species regulation, HOBr/Cl generation, damage components, so forth. In particular, review focuses on pivotal role delivery vehicles fields preservation applications. We look forward future prospects, especially field preservation, promote broader applications based antimicrobial

The determination of gallic acid (GA), one the most prevalent antioxidants in various plants, provides information for food nutrition evaluation. A novel colorimetric, fluorescent, and smartphone multi-mode GA sensing platform based on Fe3O4@Co/Ni/Al-layered double hydroxide (LDH) nanospheres was designed this study. core-shell magnetic Fe3O4@Co/Ni/Al-LDH were synthesized through a simple co-precipitation approach. They showed dominate peroxidase-like activities capable oxidizing 3,3′,5,5′-tetramethylbenzidine (TMB) into blue colored oxidation oxTMB. Meanwhile, generated oxTMB could quench fluorescence neutral red via inner filter effect. acted as an inhibitor to prevent TMB restoring red. Under optimized conditions, linear ranges 0.5–120 μmol/L with detection limits 0.137–0.415 μmol/L. Besides, sensor exhibited good selectivity toward over interferents. Moreover, it successfully utilized analyze tea beverages ideal recoveries 92.8–105%, demonstrating reliability stability practical applications. This study provided candidate nanozymes construction biosensors. self-checking function "turn on" fluorescent strategy offered superior anti-interference ability, opens up new foods.

In this study, two types of Cu-MOFs (Cu-TCPP and CuO-TCPP) with a two-dimensional layered porous structure were prepared via in situ polymerization using Cu2+, CuO, TCPP as raw materials. Both exhibited peroxidase-like activity, capable catalyzing the oxidation TMB by H2O2 to form oxTMB, resulting an absorption peak at 652 nm color change from colorless blue. Subsequently, addition AA can reduce oxTMB back TMB, causing system lighten or become colorless. Based on principle, simple rapid colorimetric method for detection was established successfully applied TAC fruits vegetables. The results showed that Cu-TCPP CuO-TCPP had large linear range ascorbic acid 0.01–100 mM (Cu-TCPP) 0.05–100 (CuO-TCPP). This study not only provides novel preparing nanozymes but also offers approach analyzing food.
