This book was released on 2012-12-02 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

Download or read book Mycotoxin Protocols written by Mary W. Trucksess and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins produced by molds are common contaminants of many important crops, including wheat, corn, rice, and peanuts. Some mycotoxins are found in fruits and vegetables. These contaminants have a broad range of toxic effects, including carcinogenicity, neurotoxicity, and reproductive and developmental toxicity. The occurrence of mycotoxins in foods is an unavoidable worldwide problem. About 80 countries have imposed regulatory limits to minimize human and animal exposure to mycotoxins. Regulatory limits, including international standards, have tremendous economic impact and must be developed using science-based risk assessments. The purpose of Mycotoxin Protocols is to provide the scientific and technological basis for analytical methods for use in obtaining the exposure data needed for risk assessments. Mycotoxin Protocols is divided into four sections, which are interc- nected. The first section: Chapters 1–5 describe the general techniques for mycotoxin analysis with emphasis on the importance of method validation based on statistical parameters; sampling procedures for collecting a sample as representative as possible of a bulk lot; the isolation of mycotoxins for use as analytical standards or for toxicological studies; the evaluation of purity and preparation of standards; and the detection and identification of impu- ties in isolated mycotoxins. Sections 2–4: Chapters 6–19 describe the most current chromatographic and immunochemical methods for studies on the major mycotoxins.
Download or read book Masked Mycotoxins in Food written by Chiara Dall'Asta and published by Royal Society of Chemistry. This book was released on 2015-11-05 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Diagnosis of Mycotoxicoses written by J.L. Richard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current problems associated with the mycotoxicoses include the recognition of an animal disease as being a mycotoxicosis and confirmation of diagnosis of the mycotoxicosis by satisfactory laboratory methods. By gathering a vast amount of scientific literature, diagnosticians can provide themselves with suitable informa tion for making such a diagnosis. However, the increased number of reported intoxications caused by fungi, the wide range in diversity of disease conditions and the chemical compounds causing the mycotoxicoses, and the ever-changing and rapid developments in the technology of mycotoxin analysis has made the gathering and assimilation of sufficient information by the diagnostician an insurmountable task. This is the reason for development of the symposium and the publication of this book; the first time that the subject of diagnosis of mycotoxicoses has been assembled in a single publication and as a compilation of topic papers by experts in this subject area. The UJNR panel on toxic microorganisms is interested in all aspects of intox ications by microorganisms as evidenced by its annual joint meetings in either the United States or Japan and its involvement in sponsoring numerous symposia and several publications in this broad scientific area. The overall mission of the National Animal Disease Center includes research efforts in the improvement or establishment of diagnostic methods for animal diseases. The UJNR panel and the NADC provided the funds and encouragement for the development of a symposium on the diagnosis of mycotoxicoses in the United States and . Tapan.
