Innovative application of surface-enhanced Raman scattering (SERS) for rapid and nondestructive analyses has been gaining increasing attention for food safety and quality. SERS is based on inelastic scattering enhancement from molecules located near nanostructured metallic surfaces and has many advantages, including ultrasensitive detection and simple protocols. Current SERS-based quality analysis contains composition and structural information that can be used to establish an electronic file of the food samples for subsequent reference and traceability. SERS is a promising technique for the detection of chemical, biological, and harmful metal contaminants, as well as for food poisoning, and allergen identification using label-free or label-based methods, based on metals and semiconductors as substrates. Recognition elements, including immunosensors, aptasensors, or molecularly imprinted polymers, can be linked to SERS tags to specifically identify targeted contaminants and perform authenticity analysis. Herein, we highlight recent studies on SERS-based quality and safety analysis for different foods categories spanning the whole food chain, ‘from farm to table’ and processing, genetically modified food, and novel foods. Moreover, SERS detection is a potential tool that ensures food safety in an easy, rapid, reliable, and nondestructive manner during the COVID-19 pandemic.

“…That is to say, the molar ratio of cobalt nitrate to nickel nitrate was set as 1:1, 2:1, 1:2, 3:1, the above test process was repeated to obtain Co1Ni1LDHs, Co2Ni1LDHs, Co1Ni2LDHs, Co2Ni1LDHs and Co3Ni1LDHs, respectively. LDHs/PES catalytic membrane was prepared by phase-tolerant invasion technology (Sun et al 2021). First, a certain amount of LDHs and PVP were evenly distributed into DMAc under strong stirring, ultrasonic treatment was carried out for 30min.…”

The Co-Ni layered double hydroxides (Co-Ni LDHs) were prepared using co-precipitation method and Co-Ni LDHs hybrid polyethersulfone membranes (Co-Ni LDHs/PES) were prepared by phase inversion method, respectively. The products were characterized by FT-IR, XRD, SEM, TEM, EDX, TGA and tensile strength test. Results showed that the Co-Ni LDHs/PES membranes as prepared had excellent mechanical properties. The decrease of membrane contact angle and the increase of membrane water flux indicated that the hydrophilicity of Co-Ni LDHs/PES membrane can be improved. The hybrid membranes showed a good catalytic performance. As the loading of LDHs was 5mg·L-1, the dosage of PMS and AO7 was 1mmol·L-1 and 0.05mmol·L-1, respectively, the degradation rate of AO7 can reach 96.58% within 20 minutes. The ion leaching of Co-Ni LDHs/PES was much less than that of Co-Ni LDHs, so, the dosage of the Co-Ni LDHs was much less than of Co-Ni LDHs. After repeated used for four times, Co-Ni LDHs/PES still has good catalytic performance. The effects of Co-Ni LDHs dosage, PMS dosage, initial pH, Cl- and HA on the degradation of AO7 were investigated. The catalytic degradation mechanism of Co-Ni LDHs/PES was studied by free radical quenching experiments and XPS analysis. The main active species in the catalytic oxidation system are SO4-, OH, 1O2 and O2- among which 1O2 and O2- were the main active species.

Textile industry effluents are heavily contaminated with dyes. The discharge of these toxic dyes into waterbodies poses a serious threat to aquatic flora and fauna. The ultimate entrance of these toxins from thereon into the food chain affects the primary and secondary consumers. Therefore, the adoption of a sustainable solution for protection against the detrimental effects associated with adulterated water is an immediate need of the hour. To address the severity of the issue, the present work aims to design an electrochemical sensing platform by modifying the glassy carbon electrode (GCE) with zinc oxide nanoparticles and amino group-functionalized multi-walled carbon nanotubes (NH 2 -fMWCNTs) for the detection of Orange II, which is a toxic azo dye. Zinc oxide nanoparticles facilitate electron transfer between the transducer and the analyte. While, the positively charged NH 2 -fMWCNTs in acidic medium help in preconcentration of negatively charged analyte molecules at the electrode/electrolyte interface. The modification of the GCE catalyzed the oxidation of Orange II, as evidenced by the negative shift of the oxidation potential and enhancement in peak current intensity. Square wave voltammetry was used to optimize various experimental conditions, such as the supporting electrolyte, pH of the electrolyte, deposition potential, and deposition time for the best performance of the designed sensor. Under the optimized conditions, the detection limit and quantification of the designed sensor were found to be 0.57 and 1.92 nM, respectively. The catalytic degradation studies of Orange II was shown to be facilitated by titanium dioxide, which acted as a photocatalyst. The addition of hydrogen peroxide further promoted the extent and rate of degradation of dye. The breakdown of Orange II was probed by the designed sensing platform electrochemically and also by UV–visible spectroscopy. The dye degraded up to 92% by following pseudo-first-order kinetics.
