The implementation of innovative packaging solutions in fresh food is playing an increasingly important role in driving the global transformation towards sustainability. Here, we demonstrated a novel GRAS preservative coating driven by intermolecular hydrogen bond self-assembly between food-derived tannic acid (TA) and gelatin (Gel). The reported TA/Gel coatings feature desirable antibacterial and antioxidant effects and good adhesion ability. Furthermore, the TA/Gel coatings demonstrate excellent performance in different packaging scenarios, demonstrating desirable preservation performance as sprayable coatings. For fresh-cut apples at 4 °C preservations, the shelf life was extended to 14 days with good commercial quality (including preferable color, protective hardness, sugar content, and weight). For fresh lettuce and beef stored at room temperature, the bactericidal rate reached more than 99% and the sensory quality are maintained well. More importantly, the green and minimalist synthesis process we proposed was expected to achieve scale-up production. Therefore, this work represents a technological solution that inspires the application of food-derived GRAS components to solve food safety problems, guiding an innovative trend for future food development.

A modified QuEChERS method in combination with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was first developed for the determination of fenbutatin oxide in six types of samples (soil, tobacco, rice, milk, pork liver, and pork). Fenbutatin oxide was extracted with acetonitrile containing 1% formic acid (v/v) and purified by dispersive solid-phase extraction using primary secondary amine (PSA) and quantitatively analyzed by HPLC-MS/MS. In the range of 0.005–1 mg/kg, a good linear relationship exists between the concentration of fenbutatin oxide and the peak area, giving a coefficient of determination (R2) of >0.99. The recoveries of fenbutatin oxide at three spiked levels were 79.04–97.12% with the relative standard deviations (RSDs) of 3.30–10.96%, and the limit of quantification (LOQ) was 0.007 mg/kg. In addition, the developed method is consistent with the reference method (R2 = 0.9896, n = 40). The method is demonstrated to be convenient and reliable for the routine monitoring of fenbutatin oxide in soil and plant- and animal-derived foods.

The development of intelligent indicator film that can detect changes in food quality is a new trend in the food packaging field. The WPNFs-PU-ACN/Gly film was prepared based on whey protein isolate nanofibers (WPNFs). Anthocyanin (ACN) and glycerol (Gly) were used as the color indicator and the plasticizer, respectively, while pullulan (PU) was added to enhance mechanical properties of WPNFs-PU-ACN/Gly edible film. In the study, the addition of ACN improved the hydrophobicity and oxidation resistance of the indicator film; with an increase in pH, the color of the indicator film shifted from dark pink to grey, and its surface was uniform and smooth. Therefore, the WPNFs-PU-ACN/Gly edible film would be suitable for sensing the pH of salmon, which changes with deterioration, as the color change of ACN was completely consistent with fish pH. Furthermore, the color change after being exposed to grey was evaluated in conjunction with hardness, chewiness, and resilience of salmon as an indication. This shows that intelligent indicator film made of WPNFs, PU, ACN, and Gly could contribute to the development of safe food.Keywords:whey protein isolate nanofibers;anthocyanin;edible film;food packaging;food spoilage

Surface-enhanced Raman scattering (SERS) with the advantages of high sensitivity, nondestructive analysis, and a unique fingerprint effect shows great potential in point-of-care testing (POCT). However, SERS faces challenges in rapidly constructing a substrate with high repeatability, homogeneity, and sensitivity, which are the key factors that restrict its practical applications. In this study, we propose a one-step chemical printing strategy for synthesizing a three-dimensional (3D) plasmon-coupled silver nanocoral (AgNC) substrate (only need about 5 min) without any pretreatments and complex instruments. The galvanic replacement between AgNO3 and Cu sheets will provide both Ag0 for the formation of silver nanostructures and Cu2+ for the polymerization of fish sperm DNA (FSDNA). The protection of AgNCs is facilitated by the crosslinked FSDNA, which can improve the stability of the substrate and promote the control of its coral-like morphology. The obtained substrate displays excellent capacity of signal enhancement due to the 3D plasmon coupling both between nanocoral tentacles and between nanocorals and Cu sheets as well. Therefore, the AgNC substrates display high activity (enhancement factor = 1.96 × 108) and uniformity (RSD < 6%). Food colorants have been widely used in various foods to improve their color, but the inevitable toxicity of colorants seriously threatens food safety. Therefore, the proposed AgNC substrates were used to directly quantify three kinds of weak-affinity food colorant molecules including Brilliant Blue, Allura Red, and Sunset Yellow assisted by the capture by cysteamine hydrochloride (CA), showing the detection limits (S/N = 3) of 0.053, 0.087, and 0.089 ppm, respectively. The SERS method has been further applied in the detection of the three kinds of food colorants in both complex food samples and urine with recoveries of 91–119%. The satisfactory detection results suggest that the facile preparation strategy of AgNC substrates will be widely used in SERS-based POCT to promote the development of food safety and on-site healthcare.

To meet the needs of food safety for simple, rapid, and low-cost analytical methods, a portable device based on a point discharge microplasma optical emission spectrometer (μPD-OES) was combined with machine learning to enable on-site food freshness evaluation and detection of adulteration. The device was integrated with two modular injection units (i.e., headspace solid-phase microextraction and headspace purge) for the examination of various samples. Aromas from meat and coffee were first introduced to the portable device. The aroma molecules were excited to specific atomic and molecular fragments at excited states by room temperature and atmospheric pressure microplasma due to their different atoms and molecular structures. Subsequently, different aromatic molecules obtained their own specific molecular and atomic emission spectra. With the help of machine learning, the portable device was successfully applied to the assessment of meat freshness with accuracies of 96.0, 98.7, and 94.7% for beef, pork, and chicken meat, respectively, through optical emission patterns of the aroma at different storage times. Furthermore, the developed procedures can identify beef samples containing different amounts of duck meat with an accuracy of 99.5% and classify two coffee species without errors, demonstrating the great potential of their application in the discrimination of food adulteration. The combination of machine learning and μPD-OES provides a simple, portable, and cost-effective strategy for food aroma analysis, potentially addressing field monitoring of food safety.

To control and on-site evaluate the contamination of organophosphorus pesticides, one direct sensing approach based on spontaneous fluorescence resonance energy transfer (FRET) was developed in this study. The luminescent metal-organic frameworks (LMOFs), a novel achievement of MOFs, could provide adjustable adsorption capacity and fluorescence index to scientific analysis was first employed to evaluate phoxim molecules in vegetables and fruits. Through the π-π recognition and FRET sensing between phoxim molecules and skeleton of Nu-1000 LMOFs probes, an ultra-low detection limit of 1.65 pg/L in the range of 5×10 −7 to 5×10 −3 mg/mL ( R 2 =0.998) was achieved in the presence of phoxim. Such simple and accurate LMOFs- FRET-based sensing strategy could offer valuable reference for developing sensitive FRET sensors and/or on-site evaluation approaches in the areas of food quality control and food safety.

This work described a sensitive and economical HPLC-UV method with FDAA derivatization to simultaneously detect 36 D/ l -amino acids, which provides higher sensitivity and lower cost than other HPLC-based methods. It was validated for linearity range (8–1000 µmol/L), limits of detection (2.68–62.44 pmol/L), limits of quantification (2.93 to 208.13 pmol/L), intraday precision (0.30 % − 5.31 %), interday precision (1.96 % − 8.04 %) and accuracy (86.53 % − 121.46 %). This method was then applied in the determination of D/L- amino acids abundance in fermented and unfermented food materials and showed the characteristics of each type of foods. The method also demonstrated good performance in another application case for the discrimination of different types of food materials based on D/L- amino acids profile. It emphasizes the ability of the method to study the characteristics, distribution and abundance of d -amino acids in foods and their potential application in food quality control.

In this study, a facile “one stone, four birds” strategy was implemented to fabricate a flexible smart food packaging tag by incorporating purple potato extract obtained using deep eutectic solvents (DESs) into a polyvinyl alcohol (PVA)/gelatin (Gel) substrate. The favorable properties of DESs enabled them to serve four different important functions in tag development: anthocyanin extraction; mitigation of anthocyanin oxidation; as a plasticizer to increase the mechanical properties of the tag; and to enhance NH 3 sensitivity. The physicochemical, microstructural, and functional properties of the tag were characterized using various methods. Moreover, density-functional theory (DFT) was used to calculate the adsorption energies for NH 3 at multiple sites on the DES. The tag was employed to monitor the freshness of shrimp and fish, whereby it underwent conspicuous color changes during 10 h of storage, which enabled classification of the products as fresh, sub-fresh, or spoiled. Overall, the developed flexible smart tag shows significant potential for application in monitoring the freshness of high-protein food.

It has the characteristics to realize the concealed component identification covered by opaque and translucent media nondestructively and rapidly. This technology gradually plays an important role in basic and applied research of numerous areas. This paper focuses on the SORS potential application in food quality and safety inspection, and a SORS detection system has been setup. The ingredients of various concealed food additives have been identified by SORS and the optimum offset distance for detection has been obtained. Meanwhile, the identification effectiveness of the system for low-concentration additives in real foods has also been evaluated.

With food safety problems abounding, it is essential to explore some efficient and effective methods for monitoring food quality. To this end, we have developed a histamine-responsive carbon dots (CDs)-based sensing system for visual monitoring of food spoilage. In this system, the aldehyde group on the surface of CDs serves as the recognition sites to combine with the amino group on histamine to form a Schiff base that effectively enhances the fluorescence. On the other hand, 1-aminoanthraquinone (ANQ) was introduced as a reference signal to endow the fluorescent probe with self-calibrating capacity. As the histamine concentration increases, linear ratiometric response was obtained accompanied with a distinguishable fluorescence color change from red to blue. Besides, test strips-based smartphone visual assays were successfully used to evaluate and monitor the histamine levels in fish samples. Our proposed sensing strategy has been demonstrated to be efficient and robust along with great potential for real-time visual monitoring of food spoilage.

Histamine is usually regarded as an important indicator for monitoring food freshness, and the detection of histamine is crucial for ensuring food safety. Herein, a high-resolution colorimetric assay for histamine determination based on nanozyme-inhibited TMB 2 + -mediated etching of gold nanorods (AuNRs) was proposed. Hydrothermal synthesis yielded CDsEDTA@Fe³ ⁺ nanozymes with Fe³ ⁺ active sites, with Vₘ = 11.17 × 10⁻⁸ M·s⁻¹ for TMB oxidation. The strong chelation between Fe 3+ and the imidazole group on histamine modulates the catalytic activity of the carbon dot nanozymes, thereby regulating the production of the oxidative end product TMB 2+ . Upon the introduction of AuNRs as the final colorimetric substrate, a rainbow-like spectrum of 5--6 distinct color changes was observed, enabling simple and rapid visual monitoring of food freshness. The limits of detection and quantification are 13.16 μM and 18.49 μM, respectively. This strategy has been effectively applied to track the genuine spoilage of shrimp and mackerel under diverse storage situations, with a recovery rate of 94.64 %-110.65 % and an RSD (n = 3) < 6 %, showing significant promise for swift and convenient detection of histamine in food products, thereby enabling the assessment of food freshness onsite.

Accurately monitoring the freshness of high-protein foods has significant implications for both food safety and public welfare. Since a large amount of hydrogen sulfide (H 2 S) is produced during spoilage-related processes, abnormal H 2 S levels are often considered an important indicator of food spoilage. Therefore, we synthesized novel nanoparticles (NPs) containing Silicon (Si) dots and CdTe quantum dots to accurately assess the amount of sulfide ions (S 2− ) and thus the quality of high-protein foods in the early stage of storage. As the concentration of S 2− increased, the fluorescence intensity of Si/CdTe NPs at λ em = 488 nm increased, while the fluorescence intensity at λ em = 620 nm was quenched. The fluorescence intensity ratio (F 620 /F 488 ) was negatively linearly correlated to S 2− concentrations in the range of 1–20 μM, with a detection limit of 0.3 μM. Furthermore, to achieve portable detection, we mixed Si/CdTe NPs with sodium carboxymethyl cellulose to prepare effective visual fluorescent sensing paper chips, which exhibited ideal porous structure, good particle dispersion, and excellent fluorescence properties. Incubating the paper chips with high-protein foods allowed for accurate monitoring of food freshness during storage. Therefore, this approach provided a reliable and portable method to determine H 2 S concentration using a novel concept to ensure the freshness and safety of high-protein foods.
