Abstract ：
High performance adsorbents are crucial for improving the efficiency of sample pretreatment and ensuring the accuracy and precision of analytical results. In this study, covalent organic framework COF-SCU1 was modified with metal-organic framework ZIF-8 for efficient extraction of toxic basic dyes in food. The prepared COFSCU1@ZIF-8 exhibited improved dispersibility and more surface negative charges compared to COF-SCU1, thereby showing enhanced adsorption performance for auramine O, rhodamine B, basic orange 21, basic orange 22 and methylene blue. The dispersive solid-phase extraction (D-SPE) for toxic basic dyes based on COFSCU1@ZIF-8 consumed tiny amount of adsorbent and solvent as well as short operation time. An analytical method for the determination of toxic basic dyes was developed based on D-SPE and high-performance liquid chromatography with detection limits of 0.9-1.6 ng mL-1. The developed method was applied to the detection of toxic basic dyes in real food samples with recoveries of 88.20-105.83 %.

Abstract ：
A novel covalent organic framework@metal organic framework composite (SCU1@ZIF-8) was prepared via a layer-by-layer assembly strategy, which was used for dispersive solid-phase extraction (D-SPE) of five illegal alkaline dyes before high-performance liquid chromatography (HPLC) analysis. Surface modification of COF-SCU1 with ZIF-8 would regulate surface potentials of COF-SCU1 and enhance its dispersibility, thereby showing better adsorption performance for illegal alkaline dyes. SCU-1@ZIF-8 based D-SPE consumed tiny amount of adsorbent and solvent as well as short operation time. Under optimized conditions, the linear ranges for detecting the five illegal alkaline dyes were 0.3-400 ng mL-1. The limits of detection (LOD) and quantification (LOQ) of the proposed method for detecting illegal alkaline dyes were in the range of 0.1-1.4 ng mL-1 and 0.3-4.6 ng mL-1, respectively. The proposed method could be applied to analyze trace illegal alkaline dyes in fish sauce, shrimp sauce, red wine and carbonated drinks. © 2024, The Authors. All rights reserved.

Abstract ：
Radio frequency (RF) heating of agri-food, especially low moisture viscous sauces (LMVS), have obvious advantages. However, uneven heating is one main problem of RF heating technology that has to be solved. Due to the unclear heating mechanism and the difficulty to measure the three-dimensional temperature distribution in the heated object, computer-aided analysis method was adopted. Based on the RF heating numerical calculation model after experimental verification and the characteristics of polyetherimide (PEI) assisted RF heating of peanut butter (PB), this study proposed an improved method for an existing pro-tocol. Meanwhile, parameters of the new protocol were optimised by the Multi-objective Global Optimi-sation (MGO) of its surrogate model. Results demonstrated that the best size of PEI block in the new protocol was & phi;100 3 9.5 mm and the positional height was 12 mm. When the pasteurisation temperature Tp was set to 70 & DEG;C and the control temperature Tc was set to 75 & DEG;C, the temperature uniformity evaluation indices, Over-shoot Temperature Control Index (OTCI) and Targeted Penetration Depth (TPD), were 0.920% and 3.975 mm, respectively. Compared with 4.845% and 4.940 mm before improvement, the new protocol achieved significant optimisation and improved the temperature uniformity effectively. This also proved the feasibility of MGO method of surrogate model in relevant studies.

Abstract ：
In this work, novel covalent organic framework modified polyacrylonitrile electrospun nanofibers (denoted: PAN@COF(TFP-p-PDA) nanofibers) was prepared and used as adsorbent of pipette tip solid-phase extraction (PTSPE) for the effective extraction of estrogens in milk followed by high-performance liquid chromatographyfluorescence detector (HPLC-FLD). The PAN@COF(TFP-p-PDA) nanofibers was prepared via a secondary growth method for the first time. The characterization results of PAN@COF(TFP-p-PDA) nanofibers showed that a continuous, dense and uniform COFs layer was grown on the surface of PAN electrospun nanofibers, and PAN@COF(TFP-p-PDA) nanofibers had high Brunauer-Emmett-Teller (BET) specific surface area (303.91 m2 g- 1). Several important parameters of PT-SPE affecting the extraction efficiency were systematically studied, and the optimized conditions were comprised of 8 mg PAN@COF(TFP-p-PDA) nanofibers, pH 7 and 1.5 mL of 15% ammonia-acetonitrile (V:V) as elution solvent. Under optimal conditions, the linear range of the tested estrogen was estimated from 1.13 to 100 ng mL-1 with correlation coefficient larger than 0.997. The limits of detection (LOD) and limit of quantification (LOQ) were calculated as 0.34-0.57 ng mL-1 and 1.13-1.9 ng mL-1, respectively. The practicality of the developed analytical method was verified through determination of estrogens in milk samples, satisfactory recoveries (87.0%-114.8%) were obtained with relative standard deviations (RSDs) smaller than 8.6%.
