“…This identification method was initially used for the identification of species of bacteria, fungi, and viruses (e.g., Claydon et al, 1996;Fenselau and Demirev, 2001), and is still widely used (e.g., Seng et al, 2010;Chalupová et al, 2014;Singhal et al, 2015). In addition, MALDI-TOF MS has been used for species identification of microalgae (Baumeister et al, 2020), microorganisms (Maier et al, 2006) and various metazoan taxa including insects (Feltens et al, 2010), fish (Volta et al, 2012;Shao and Bi, 2020), and calanoid copepods (Riccardi et al, 2012;Laakmann et al, 2013;Bode et al, 2017). Previous studies with several taxa as study subjects confirmed that MALDI-TOF MS is a reliable and fast alternative method for species identification.…”

MALDI Time-of-Flight Mass Spectrometry (MALDI-TOF MS) provides a fast and reliable alternative method for species-level identification of pathogens and various metazoans. Compared to the commonly used mitochondrial cytochrome c oxidase subunit I (mtCOI) barcoding, advantages of MALDI-TOF MS are rapid species identifications and low costs. In this study, we used MALDI-TOF MS to determine whether spectra patterns of different species can be used for species identification. We obtained a total of 138 spectra from individual specimens of Tigriopus, which were subsequently used for various cluster analyses. Our findings revealed these spectra form three clear clusters with high AU value support. This study validates the viability of MALDI-TOF MS as a methodology for higher-resolution species identification, allowing detection of cryptic species of harpacticoida. In addition, we propose a new species, Tigriopus koreanus sp. nov. by utilizing integrative methods such as morphological comparison, mtCOI barcoding, and MALDI-TOF MS.

“…The results indicated that the developed method can be a promising strategy to evaluate the change in fish muscle or other animal muscle-based foods (114). In recent years, mass spectrometric, metabolomic, and chemometric techniques have been used to investigate different fish for taxonomic classification, authentication, and quality assessment (115)(116)(117). The pre-treatment of the fish muscle samples before subjecting to spectroscopic analysis was reported to increase in effectiveness and efficacy of analysis and hence better reproducible results (118).…”

Milk and milk products, meat, fish and poultry as well as other animal derived foods occupy a pronounced position in human nutrition. Unfortunately, fraud in the food industry is common, resulting in negative economic consequences for customers as well as significant threats to human health and the external environment. As a result, it is critical to develop analytical tools that can quickly detect fraud and validate the authenticity of such products. Authentication of a food product is the process of ensuring that the product matches the assertions on the label and complies with rules. Conventionally, various comprehensive and targeted approaches like molecular, chemical, protein based, and chromatographic techniques are being utilized for identifying the species, origin, peculiar ingredients and the kind of processing method used to produce the particular product. Despite being very accurate and unimpeachable, these techniques ruin the structure of food, are labor intensive, complicated, and can be employed on laboratory scale. Hence the need of hour is to identify alternative, modern instrumentation techniques which can help in overcoming the majority of the limitations offered by traditional methods. Spectroscopy is a quick, low cost, rapid, non-destructive, and emerging approach for verifying authenticity of animal origin foods. In this review authors will envisage the latest spectroscopic techniques being used for detection of fraud or adulteration in meat, fish, poultry, egg, and dairy products. Latest literature pertaining to emerging techniques including their advantages and limitations in comparison to different other commonly used analytical tools will be comprehensively reviewed. Challenges and future prospects of evolving advanced spectroscopic techniques will also be descanted.

“…MALDI-TOF combined with multivariate analysis was exploited [89] for the development of a method to directly analyze fish skin or muscle tissues surface, for authentication purposes. Samples were quickly discriminated, hinting at potential future developments for the authentication of seafood in general and/or other protein food products.…”

Chemical analysis of food products relating to the detection of the most common frauds is a complex task due to the complexity of the matrices and the unknown nature of most processes. Moreover, frauds are becoming more and more sophisticated, making the development of reliable, rapid, cost-effective new analytical methods for food control even more pressing. Over the years, MALDI-TOF MS has demonstrated the potential to meet this need, also due to a series of undeniable intrinsic advantages including ease of use, fast data collection, and capability to obtain valuable information even from complex samples subjected to simple pre-treatment procedures. These features have been conveniently exploited in the field of food frauds in several matrices, including milk and dairy products, oils, fish and seafood, meat, fruit, vegetables, and a few other categories. The present review provides a comprehensive overview of the existing MALDI-based applications for food quality assessment and detection of adulterations.
