Molecularly imprinted polymers (MIPs) have gained significant traction in food contaminant analysis owing to their tailorable binding sites and functionalities. Nevertheless, the analysis performance of MIPs fabricated via conventional imprinting methods has been hindered by heterogeneous binding cavities. Herein, we first present a template-derivatization-based oriented surface imprinting strategy to construct paper-based metal organic framework (MOF)-imprinted chips with highly ordered MIPs (FP@B-MOF@MIP) for enhanced sulfadiazine (SDZ) analysis. Cis-dihydroxy-derived SDZ (SDZ-CD) as the dummy template endowed imprinting cavities with high orientation via boronate-affinity oriented recognition. FP@B-MOF@MIP achieved good absorption capacity (76.30 mg g−1) and selectivity with the imprinting factor of 5.6 for SDZ. A colorimetric sensor based on FP@B-MOF@MIP was further successfully constructed for the visual determination of trace SDZ in food samples with a low detection limit of 0.0048 mg L−1. This work provides a flexible strategy to improve the performance of MIPs for monitoring trace contaminants in foodstuffs.

Facing the urgent need for sustainable and functional food packaging, developing high-performance materials from natural polymers is crucial. Herein, we propose a green strategy inspired by crustacean exoskeletons to construct lignin–metal polyphenol networks (L-MPNs) via proton-based ionic liquid pretreatment and metal-ion coordination. This forms a stable 3D network utilizing lignin's phenolic hydroxyl groups, which significantly enhances antioxidant activity, achieves >99% UV shielding, and exhibits 92.5% DPPH radical scavenging capacity. Applied to paper packaging, Ferric-ion-coordinated lignin-metal polyphenol networks (FL-MPNs, 100 g/m2) impart excellent barrier and antioxidant properties alongside maintained mechanical strength, cutting water vapor transmission by ∼40%. In freshness tests, they reduced mass loss to 3.52% and pH change to 0.17, effectively inhibiting food deterioration. Thus, FL-MPNs advance lignin valorization for next-generation sustainable smart packaging to ensure safer, more stable food preservation.

This study identified three novel multi-target antidiabetic peptides (GFPAGFVFG, YPQPLL, FGFVTF) from Qingke protein hydrolysates. Sequential enzymatic hydrolysis, purification, LC-MS/MS, and molecular docking revealed their strong binding to α-amylase, α-glucosidase, and DPP-IV via hydrophobic and hydrogen-bond interactions. In vitro assays showed potent concurrent inhibition of all three enzymes, with IC₅₀ values of 0.15–1.14, 0.16–0.69, and 0.02–0.75 mg/mL, respectively. Notably, the peptides exhibited a synergistic multi-enzyme inhibitory profile, collectively targeting carbohydrate digestion and incretin degradation pathways—a mechanistic advantage over single-target drugs such as acarbose (α-glucosidase inhibitor) or sitagliptin (DPP-IV inhibitor). Inhibition kinetics further revealed distinct modes of action (competitive, non-competitive, and mixed-type), supporting their potential as multi-target therapeutic candidates. These findings highlight highland barley as a sustainable source of bioactive peptides with synergistic potential for the management of postprandial hyperglycemia and type 2 diabetes.

3-Methyl-2,4-nonanedione (MND) is an impact oxidation marker of red wines, whose formation mechanisms in wines have received little attention until now. We first studied press wines (PW) containing large amounts of this β-diketone (∼120 ng/L) according to the vintage and the press type, thus suggesting a high level of precursors. The ethyl esters of two fatty acids belonging to the furan fatty acid (FFA) family were identified for the first time: DiMeF(9,5) and DiMeF(11,5). We developed a method for quantifying these compounds by GC-TOF-MS after ethylation. DiMeF(9,5) was detected at trace level whereas the highest DiMeF(11,5) levels reached 50 μg/L in PW. The oxidation of the latter at this concentration explains for the first time the higher MND levels detected in PW. In addition, the first identification of this FFA in Cabernet Sauvignon grapes by GCxGC TOF MS suggests that these new compounds in wines have a varietal origin.

Unlike wheat and rice, which are predominantly consumed as refined grains, rye (Secale cereale L.) is mostly consumed as whole grain, making it an ideal vehicle of dietary fiber and phytochemicals. This study profiled arabinoxylans (AX), alkylresorcinols (AR) and phenolic acids in 180 genetically diverse rye accessions from 32 countries. Total AX ranged 70.1–133.0 mg/g, water-extractable AX 6.2–12.7 mg/g, total AR 718.7–2322.2 μg/g and ferulic acid 476.5–1778.1 μg/g on a dry matter basis. Developed cultivars matched or exceeded landraces for total AX (+8%) and ferulic acid (+19%), indicating that modern breeding has not compromised nutritional quality. Correlations were positive among bioactive classes but negative with thousand kernel weight. Elite accessions such as Caribou combined high levels of all three components, offering immediate options for high-fiber, antioxidant-rich product formulation. Overall, these findings broaden the biochemical landscape of rye and identify specific germplasm for functional food innovation.

Concerns about synthetic food dyes being associated with adverse health effects have increased interest in safer, natural alternatives, which provide vivid color and beneficial bioactive properties. This study explores the beetroot waste valorization by extracting bioactive pigments using 15 edible, ready-to-use Natural Deep Eutectic Solvents (NADES). The five best-performing extracts–showing highest total phenolic content, betalain yield and antioxidant capacity–were obtained with betaine/xylitol/1,3-propanediol, betaine/fructose, fructose/glucose/glycerol, fructose/xylitol/glycerol, and choline chloride/citric acid NADES systems, and applied as natural colorants in cookies. Choline chloride/citric acid NADES extract exhibited the strongest anti-diabetic (98 ± 1%), anti-obesity (53 ± 3%), and antimicrobial activity against four foodborne pathogens, enzymatic browning inhibition (98 ± 2%), and produced the most intense coloration in the cookie model system. It showed dose-dependent cytotoxicity, whereas remaining extracts were non-toxic. Тhese findings demonstrate the feasibility of valorizing beetroot by-products into sustainable, health-promoting food colorants aligned with circular-economy and clean-label strategies.

Wheat flour and its derivatives are staple foods worldwide, making their quality and safety essential for the food industry and consumers. Conventional analytical methods are often slow, costly, and destructive. In recent years, infrared spectroscopy, particularly near-infrared (NIR) and mid-infrared (MIR), has emerged as a rapid, cost-effective, and non-destructive alternative for wheat flour assessment. This review summarizes recent advances in applying these techniques to determine quality parameters, monitor functional properties, detect adulterants, verify authenticity, and evaluate contamination risks. The integration of spectroscopy with chemometric methods and machine learning has improved predictive accuracy and robustness, supporting real-time and in situ analysis. In addition, the use of calibration models, wavelength selection strategies, and deep learning approaches has further enhanced analytical performance. Overall, NIR and MIR spectroscopy stand out as key tools to optimize quality control and safety in wheat flour, contributing to fast, reliable, and sustainable analytical systems for the food industry.

Porous wheat starch (PWS) holds promise as a functional ingredient, but its application is often limited by its poor physicochemical stability. This study employed sodium hypochlorite oxidation and sodium trimetaphosphate cross-linking to enhance the structural and functional properties of PWS. Results revealed that the A-type crystal structure of modified PWS was preserved at the long-range level, and the formation of carbonyl (CO, 1640 cm−1) and phosphate diester bonds (C-O-P-O-C, 887 cm−1) confirmed the occurrence of oxidation and crosslinking reactions. The dual-modified PWS exhibited substantial improvements in thermal stability, shear resistance, and viscoelastic properties and remarkably enhanced adsorption capacities for water (109.83% ± 3.11%), oil (120.34% ± 3.40%), and proanthocyanidin (6.43 ± 0.19 mg/g)—substantially outperforming single-modified starch. These findings reveal a strong synergistic mechanism for engineering high-performance starch derivatives and establish dual-modified PWS as a promising bioactive compound carrier and versatile food industry functional ingredient.

Fraudulent substitution of sturgeon caviar with lower-value roe or non-sturgeon eggs poses risks to consumer protection and sturgeon conservation. In this study, a dual-mode loop-mediated isothermal amplification (LAMP) assay was developed for rapid and on-site authentication of sturgeon (Acipenseridae)-derived components in caviar. This assay integrates SYTO-9 real-time fluorescence and hydroxynaphthol blue colorimetry within a closed-tube system. Primers targeting a conserved region of the Acipenser and Huso cytochrome b gene generated a 190-bp amplicon, enabling detection of sturgeon genomic DNA down to 0.1 pg at 64 °C within 10 min, accompanied by a visible sky-blue color change and fluorescence signal. High analytical specificity was demonstrated with no amplification observed from 14 non-Acipenseridae fish samples. Validation using 17 commercial caviar products showed complete agreement with sequencing-based species identification. The simplicity, speed, and closed-tube format of this assay reduce equipment needs and contamination risks, supporting its suitability for regulatory, commercial, and conservation applications.

Dibutyl phthalate (DBP) contamination severely endangers human health and ecosystems. For sensitive and convenient detection of DBP, a colorimetric-photothermal dual-response lateral flow immunoassay (LFIA) based on hollow Bi2S3 submicron star-shaped particles (Bi2S3 HSSPs) was developed. The positively charged Bi2S3 HSSPs synthesized via a one-pot hydrothermal method enable efficient labeling with antibodies. After assembling the test strips, featuring excellent stability, dispersibility, and appropriate particle size, Bi2S3 HSSPs are suitable for chromatographic process and exhibit strong colorimetric signals. Notably, the unique hollow structure and star-like surface endow superior photothermal conversion, providing sensitive temperature responses. The limit of detection (LOD) for DBP is 1.52 ng/mL, with a detection range of 1.56–300 ng/mL and recoveries ranging from 94.2 % to 114.2 %. The Bi2S3 HSSPs as signal labels performed excellently in labeling, chromatography, colorimetry, and photothermal response, and providing a inspirational reference for the selection of labeling materials and improvement of DBP rapid immunoassay.
