Book Description
Modern Methods in the Analysis and Structural Elucidation of Mycotoxins presents available methods of analysis and structural elucidation of mycotoxins by recognized experts in the various disciplines. The approach in each chapter of the book is to present each method initially in theoretical terms and then to review the method as it specifically applies to the analysis and/or structural elucidation of mycotoxins. Comprised of 15 chapters, the book's opening chapters deal with screening, sampling, and survey methods for mycotoxins and toxigenic fungi. This is followed by chapters dealing mostly with methods for structural elucidation, such as NMR and X-ray crystallography and IR and UV spectroscopy, as well as biosynthetic techniques. Significant chapters consider the analytical methods for mycotoxin analyses, including enzyme-linked immunosorbent assay system and tandem mass spectrometry. The concluding chapter examines the mycotoxin analytical problem in taxonomic or ecological terms. This book is of value to food and feed researchers, scientists, and manufacturers who are interested in product contamination control.

Book Description
Mycotoxins are secondary metabolites produced by the fungi of different species (mainly Aspergillus, Fusarium, and Penicillium), with toxic effects for humans and animals. These mycotoxins can contaminate food and feed. The European Union (EU) has established the maximum permitted or recommended levels for well-known mycotoxins in different foodstuffs. However, there are other mycotoxins that are not included in the regulations: the “emerging mycotoxins” (whose toxicity is still not clear), and the “modified or masked mycotoxins” (produced as a consequence of a detoxification strategy of the host plant of the fungus or during food processing). These mycotoxins could pose a risk and should also be taken into account. In order to assure consumers’ health, analytical methods for the accurate determination of mycotoxins in different food matrices and feeds are required. In this sense, liquid chromatography tandem mass spectrometry (LC–MS/MS) is a powerful tool for their unique identification and quantification. Moreover, the use of high-resolution mass spectrometry (HRMS) allows one to identify novel mycotoxins and targeted/untargeted approaches for study. This Special Issue compiles recent applications of LC–MS/MS in mycotoxin studies, as well as the development and validation of new analytical methods for their identification and quantification in different food matrices and feed, occurrence studies, and the biomonitoring of mycotoxins and their metabolites in biological fluids.

Book Description
The first book to cover this fast developing field, Masked Mycotoxins in Food will provide a full overview of the issues relating to the toxicology of masked mycotoxins present in food products. Mycotoxins are naturally occurring chemicals produced by moulds that can grow on crops and foodstuffs. Masked mycotoxins are modified mycotoxins, due to this modification many cannot be detected using standard analytical techniques, for example HPLC and ELISA, and further research is needed to understand the health risks and threats from these modified compounds.Masked mycotoxin research is an area of toxicological research that has gained significant interest and momentum in recent years. The aim of this book is to provide a full picture of the topic, from the masked mycotoxin formation in plants to their catabolic fate in humans. The book also provides new insights and will highlight possible gaps in the knowledge base of this relatively new area. Edited and written by World renowned experts working within the field, this book is of interest to toxicologists and biochemists, but also food scientists and agricultural researchers working in industry and academia.

Book Description
Traditionally mycotoxins are mainly determined by immunoassay screening methods or by single compound chromatographic analytical methods, based on immunoaffinity column cleanup followed by a separation step using thin layer chromatography (TLC), gas chromatography (GC) or liquid chromatography (LC), which were coupled to conventional detectors such as electron capture detection (ECD), fluorescence or UV-visible detection. In some cases, especially when fluorescence detection was used, it was necessary to include a pre- or post-column derivatisation step in order to increase the detection capabilities of the analytical method. However, the application of hyphenated chromatographic techniques, especially LC coupled to mass spectrometry (MS) and LC-MS/MS, has several advantages including simple treatment, due to further clean up procedures with immunoaffinity columns can be avoided, rapid determination and high sensitivity.

Book Description
The evaluation of the presence of mycotoxins in different matrices is achieved through different analytical tools (including quantitative or qualitative determinations). Studies of mycotoxin isolation, using chromatographyc equipment coupled to spectrometry detectors (QTrap-MS/MS, MS/MS tandem, QTOF-MS/MS), are the most useful tools to control their presence. All these studies represent key steps in the establishment of the limits of detection, limits of quantification, points of identification, accuracy, reproducibility, and repeatability of different procedures. The maximum permitted or recommended levels for mycotoxins in different matrices are within a wide range (including the levels tolerated by infants and animals). In addition, decontaminated strategies, as well as control and evaluation of exposure, are demanded by authorities and food safety systems. These authorities are not only concerned with the determination of mycotoxin presence but also with the toxicological effects of mycotoxins, and in vivo or in vitro assays are necessary for a complete evaluation. In fact, these assays are the basis for the control and prevention of population exposure to mycotoxins in dietary exposure studies. The most recent surveys focused on regulated mycotoxins (aflatoxins, fumonisins, trichothecenes, and zearalenones) and emerging toxins, such as enniatins and beauvericin in adult consumers, while very few studies have monitored mycotoxin levels in infant products. This Book of Toxins comprises 11 original contributions and one review. New findings regarding presence of mycotoxins in aromatic and medicinal plants, mango and orange juice, juices, pulps, jams, and beer, from Morocco, Pakistan, and Portugal are reported. In these studies, innovative techniques to study their presence has been developed, including liquid chromatography coupled with time-of-flight mass spectrometry to analyse mycotoxins and conjugated mycotoxins. Novel strategies to detect mycotoxin presence and comparisons the characteristics of a rapid quantitative analysis of different mycotoxins (deoxynivalenol, ochratoxin A, patulin, sterigmatocystin, and zearalenone) are also presented using acetyl- and butyrylcholinesterases and photobacterial strains of luminescent cells. Additionally, toxicological effects of zearalenone metabolites and beauvericin on SH-SY5Y neuronal cells are presented. One important point in the control of mycotoxins is related to decontaminated strategies, and in this sense the efficacy of potentially probiotic fruit-derived Lactobacillus isolates in removing aflatoxin M1 (AFM1) is presented. Other mycotoxin decontaminated techniques included in this book are electron beam irradiation (EBI) and degradation of zearalenone and ochratoxin A using ozone. Finally, a review that summarizes the newly discovered macrocyclic trichothecenes and their bioactivities over the last decade is included.
