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.

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 Meeting the mycotoxin menace written by D. Barug and published by BRILL. This book was released on 2023-08-28 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mycotoxins are toxic secondary metabolites of moulds belonging essentially to the Aspergillus, Penicillium, and Fusarium genera. They can be produced on a wide range of agricultural commodities and under a diverse range of situations. Due to their various toxic effects and their good thermal stability, the presence of mycotoxins in foods and feeds is potentially hazardous to the health of both humans and animals. Mycotoxins may cause damage to e.g. liver, kidney or the nervous system, some are even carcinogenic. There is growing concern for ways in which these fungi and their mycotoxins can be prevented from entering the human and animal food chain. And worldwide changes in legislation ever increase the need for more precise and sensitive mycotoxin analytical methods. 'Meeting the mycotoxin menace' contains the peer-reviewed papers of the second World Mycotoxin Forum held 17-18 February 2003 in Noordwijk, the Netherlands. The book focuses on the various aspects related to the presence, prevention, control, sampling and analysis of mycotoxins in agricultural commodities, foods and feeds. In this publication special attention is given to new developments in this field. The editors firmly believe that the very nature of the themes chosen and the excellence of the papers by invited experts from various disciplines will draw an audience from both the food and feed industry, regulatory authorities and science."
Download or read book Mycotoxins Study written by Cristina Juan García and published by MDPI. This book was released on 2021-09-07 with total page 156 pages. Available in PDF, EPUB and Kindle. 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 Determining Mycotoxins and Mycotoxigenic Fungi in Food and Feed written by Sarah De Saeger and published by Elsevier. This book was released on 2011-02-07 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins - toxic secondary metabolites produced by mycotoxigenic fungi – pose a significant risk to the food chain. Indeed, they may be the most hazardous of all food contaminants in terms of chronic toxicity and legislative limits on their levels in food and feed continue to be developed worldwide. Rapid and reliable methods for the determination of both mycotoxigenic fungi and mycotoxins in food and feed are therefore essential. This book reviews current and emerging methods in this area. Part one focuses on the essentials of mycotoxin determination, covering sampling, sample preparation and clean-up and key determination techniques, such as chromatographic separation, liquid chromatography-mass spectrometry and immunochemical methods. Part two then goes on to describe quality assurance, official methods and performance criteria for determining mycotoxins in food and feed. Topics covered include laboratory accreditation, method validation and measurement uncertainty. The development and analysis of biomarkers for mycotoxins are discussed in part three. Individual chapters focus on detecting exposure in humans and animals. Part four is concerned with the processes involved in determining mycotoxigenic fungi in food and feed. It also describes the identification of genes and gene clusters involved in mycotoxin synthesis, as well as DNA barcoding of toxigenic fungi. Finally, part five explores some of the emerging methods for mycotoxin analysis, ranging from bio-sensing to spectroscopic techniques. With its distinguished editor and international team of contributors, Determining mycotoxins and mycotoxigenic fungi in food and feed is a standard reference for all those concerned with reducing mycotoxin contamination in the food chain. Focuses on the essentials of mycotoxin determination, covering sampling, sample preparation, clean-up and key determination techniques Documents quality assurance and official methods and performance criteria for determining mycotoxins in food and feed Explores the processes of determining mycotoxigenic fungi in food and feed including the identification of genes and gene clusters
