“…These authors used paprika as a powdered-food model. In a recent study, Zhang et al [ 148 ] developed a precise SERS method to qualify and quantify hydroxy-α-sanshool (α-SOH) in hotpot seasoning, restraining the interference of capsaicin. For this, the samples require pre-treatment with metal–organic frameworks (MOFs), exhibiting an Fe-BTC MOF significant anti-interference effect.…”

There is a necessity to protect the quality and authenticity of herbs and spices because of the increase in the fraud and adulteration incidence during the last 30 years. There are several aspects that make herbs and spices quite vulnerable to fraud and adulteration, including their positive and desirable sensorial and health-related properties, the form in which they are sold, which is mostly powdered, and their economic relevance around the world, even in developing countries. For these reasons, sensitive, rapid, and reliable techniques are needed to verify the authenticity of these agri-food products and implement effective adulteration prevention measures. This review highlights why spices and herbs are highly valued ingredients, their economic importance, and the official quality schemes to protect their quality and authenticity. In addition to this, the type of frauds that can take place with spices and herbs have been disclosed, and the fraud incidence and an overview of scientific articles related to fraud and adulteration based on the Rapid Alert System Feed and Food (RASFF) and the Web of Science databases, respectively, during the last 30 years, is carried out here. Next, the methods used to detect adulterants in spices and herbs are reviewed, with DNA-based techniques and mainly spectroscopy and image analysis methods being the most recommended. Finally, the available adulteration prevention measurements for spices and herbs are presented, and future perspectives are also discussed.

“…The design of SERS substrates should be tailored to the specific target substances. In food safety applications, the target substances can be categorized into two groups: small amount molecules [ 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ] and tiny biomaterials, such as cells [ 89 , 90 , 91 , 92 ], cell walls [ 93 , 94 , 95 , 96 ], and spores [ 97 , 98 , 99 , 100 ]. The key distinction between these two categories lies in their size.…”

“…The key distinction between these two categories lies in their size. Molecules are typically smaller than 100 nm and can be accommodated within the hotspot of the SERS substrate [ 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ]. On the other hand, tiny biomaterials are generally larger than 100 nm and cannot fit into the small hotspot of the SERS substrate [ 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 ].…”

Sustainable and safe food is an important issue worldwide, and it depends on cost-effective analysis tools with good sensitivity and reality. However, traditional standard chemical methods of food safety detection, such as high-performance liquid chromatography (HPLC), gas chromatography (GC), and tandem mass spectrometry (MS), have the disadvantages of high cost and long testing time. Those disadvantages have prevented people from obtaining sufficient risk information to confirm the safety of their products. In addition, food safety testing, such as the bioassay method, often results in false positives or false negatives due to little rigor preprocessing of samples. So far, food safety analysis currently relies on the enzyme-linked immunosorbent assay (ELISA), polymerase chain reaction (PCR), HPLC, GC, UV-visible spectrophotometry, and MS, all of which require significant time to train qualified food safety testing laboratory operators. These factors have hindered the development of rapid food safety monitoring systems, especially in remote areas or areas with a relative lack of testing resources. Surface-enhanced Raman spectroscopy (SERS) has emerged as one of the tools of choice for food safety testing that can overcome these dilemmas over the past decades. SERS offers advantages over chromatographic mass spectrometry analysis due to its portability, non-destructive nature, and lower cost implications. However, as it currently stands, Raman spectroscopy is a supplemental tool in chemical analysis, reinforcing and enhancing the completeness and coverage of the food safety analysis system. SERS combines portability with non-destructive and cheaper detection costs to gain an advantage over chromatographic mass spectrometry analysis. SERS has encountered many challenges in moving toward regulatory applications in food safety, such as quantitative accuracy, poor reproducibility, and instability of large molecule detection. As a result, the reality of SERS, as a screening tool for regulatory announcements worldwide, is still uncommon. In this review article, we have compiled the current designs and fabrications of SERS substrates for food safety detection to unify all the requirements and the opportunities to overcome these challenges. This review is expected to improve the interest in the sensing field of SERS and facilitate the SERS applications in food safety detection in the future.

“…In the FT-IR spectrum of Cu 3 (BTC) 2 , the characteristic absorption bands of the COO − group appeared at 1630 cm −1 (asymmetric stretching vibration), 1440 cm −1 (symmetric stretching vibration), and 1380 cm −1 (symmetric stretching vibration). 42,43 In addition, the bending vibration of a water molecule was observed at 1620 cm −1 , while the absorption band at 1580 cm −1 represented chemisorbed water coordinated with Cu sites. 44,45 As calculated via TGA (Figure 4b), these coordinated water molecules that replaced the BTC 3+ bridging ligands that generated the missing linker defects gave a molecular formula of Cu 3 (BTC) 1.42 , which resulted in a measured 29% deviation from the ideal [Cu 3 (BTC) 2 ] modulator:linker ratio.…”

Metal−organic frameworks (MOFs) are limited by small pores and buried active sites, and their enzyme-like catalytic activity is still very low. Herein, laccase was employed as the organic component to construct laccase@Cu 3 (BTC) 2 nanofractal microspheres. During the preparation process, laccase adsorbed Cu 2+ by electrostatic attractive interaction, then combined with Cu 2+ by coordination interaction, and finally induced the in situ growth of H 3 BTC 2 in multiple directions by electrostatic repulsion. Interestingly, electrostatic repulsion was tuned efficiently by adjusting the Cu 2+ concentration to obtain laccase@Cu 3 (BTC) 2 nanofractal microspheres (nanosheet microspheres, nanorod microspheres, and nanoneedle microspheres). Laccase@Cu 3 (BTC) 2 nanorod microspheres exhibited the highest catalytic efficiency, which was 14-fold higher than that of smooth microspheres. The mechanism of the improvement of catalytic activity in the degradation of BPA was proposed for the first time. The enhanced catalytic activity depended on the adsorption effect of the nanorod framework and dual cycle synergistic catalysis of Cu + /Cu 2+ active sites, which accelerated substrate diffusion and electron transfer. The catalytic mechanism of enzyme@MOF nanofractal microspheres not only deepens our understanding of enzyme and MOF synergistic catalysis but also provides new insights into the design of catalysts.
