“…Most of the optical sensors for BAs follow the classical sensor design where a probe for recognition is immobilized in a membrane and/or fixed on a suitable support which can be paper [11][12][13], glass [12,14], TLC plates [15][16][17], microtiter plates [18], and test tubes [19]. To deposit the recognition layer, knife coating, spin coating, or simple soaking may be used.…”

“…To deposit the recognition layer, knife coating, spin coating, or simple soaking may be used. The probe is mostly embedded into a polymer layer as a thin film [15,20], or eventually allowed to settle on another film of, e.g., gold or silicon [21], on polymer particles [18,22,23], on a hydrogel [24], or inside nanofibers [25]. Then, various optical methods are applied for detection.…”

Optical sensors for determination of biogenic amines in food

et al. 2020

This review presents the state-of-the-art of optical sensors for determination of biogenic amines (BAs) in food by publications covering about the last 10 years. Interest in the development of rapid and preferably on-site methods for quantification of BAs is based on their important role in implementation and regulation of various physiological processes. At the same time, BAs can develop in different kinds of food by fermentation processes or microbial activity or arise due to contamination, which induces toxicological risks and food poisoning and causes serious health issues. Therefore, various optical chemosensor systems have been devised that are easy to assemble and fast responding and low-cost analytical tools. If amenable to on-site analysis, they are an attractive alternative to existing instrumental analytical methods used for BA determination in food. Hence, also portable sensor systems or dipstick sensors are described based on various probes that typically enable signal readouts such as photometry, reflectometry, luminescence, surface-enhanced Raman spectroscopy, or ellipsometry. The quantification of BAs in real food samples and the design of the sensors are highlighted and the analytical figures of merit are compared. Future instrumental trends for BA sensing point to the use of cell phone-based fully automated optical evaluation and devices that could even comprise microfluidic micro total analysis systems.

“…red, methyl orange and screened methyl orange) and were able to correlate colour changes with TVB-N, TVC, and residual nitrite (RN). In a second study (Xiaowei, 2016), also for Yao-meat spoilage detection, some indicators were incorporated into TiO 2 in order to obtain a nanoporous sensor array able to detect the trimethylamine (TMA). The sensor enabled the visual detection of TMA gas from 10 to 60 ppm with significant response.…”

Food waste is one of the main issues for international organisms. It is not only an ethical and economic issue but it also depletes the environment of limited natural resources. Among strategies suitable for fighting such challenge, intelligent packaging is an interesting tool to reduce waste derived from households and retailers. A revision of 45 recent advances in the area of optical systems for freshness monitoring is reported herein. The study covers fruits, vegetables, fish products and meat since they are the most representative fields of application. Furthermore, a discussion about the main research challenges and opportunities that will be faced by intelligent packaging in the coming years is included.

“…The system showed no leaching, and cytotoxicity tests confirmed compatibility. Another example was described by using dyes loaded within porous TiO 2 nanoparticles [ 49 ]. In other examples, total volatile basic nitrogen (TVB-N) was quantified by an organic semiconductor gas sensor with a porous top metal electrode sensor with a nanostructured surface for enhanced gas adsorption [ 50 ].…”

The growing interest in food quality and safety requires the development of sensitive and reliable methods of analysis as well as technology for freshness preservation and food quality. This review describes the status of chemical and biological sensors for food monitoring and smart packaging. Sensing designs and their analytical features for measuring freshness markers, allergens, pathogens, adulterants and toxicants are discussed with example of applications. Their potential implementation in smart packaging could facilitate food-status monitoring, reduce food waste, extend shelf-life, and improve overall food quality. However, most sensors are still in the development stage and need significant work before implementation in real-world applications. Issues like sensitivity, selectivity, robustness, and safety of the sensing materials due to potential contact or migration in food need to be established. The current development status of these technologies, along with a discussion of the challenges and opportunities for future research, are discussed.
