This book was released on 2014-10-10 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanogenic glycosides are natural plant toxicants. They are widely distributed in the plant kingdom including many that are commonly consumed by humans. Cyanogenic glycosides serve as important chemical weapons in the defence of the plant against herbivores because of the potential to generate toxic hydrogen cyanide. Amygdalin is the most common of the cyanogenic glycosides. It is present in abundance in the seeds and kernels of fruits such as apricot, almond, apple, cherry, plum, peach and nectarine. When cyanogenic plants are ingested by humans, enzymes produced by the intestinal microflora are able to hydrolyse intact cyanogenic glycoside to produce hydrogen cyanide in vivo. Cyanide toxicity can occur in humans following the consumption of cyanogenic glycosides in plants at doses between 0.5-3.5 mg kg-1 body weight. Consumption of cyanogenic plants such as cassava root, almond or apricot kernels, has been reported to cause both acute and sub-acute health problems (depending on dose) such as headache, nausea, vomiting, abdominal pain, dizziness, weakness, mental confusion, convulsions, cardiac arrest, circulatory and respiratory failure, coma and in extreme cases death.

Available in PDF, EPUB and Kindle. Book excerpt: Cyanogenic glycosides are natural plant toxins that are present in several plants, most of which are consumed by humans. Cyanide is formed following the hydrolysis of cyanogenic glycosides that occur during crushing of the edible plant material either during consumption or during processing of the food crop. Exposure to cyanide from unintentional or intentional consumption of cyanogenic glycosides may lead to acute intoxications, characterized by growth retardation and neurological symptoms resulting from tissue damage in the central nervous system (CNS). Processing methods can detoxify cyanogenic glycosides and reduce the risk of cyanide poisoning. The efficiency of cyanide removal, however, depends on the processing technique employed and the extent of processing. Processing operations such as fermentation, boiling/cooking, and drying, applied to process food-containing cyanogenic glycosides have been reported to reduce cyanide content to acceptably safe levels. The present review discusses the level of cyanogenic glycosides in specific plant foods, health implications of consuming cyanogenic plants and effect of various processing method on cyanogenic glycosides with updated information gathered from the published reports on cyanogenic glycosides.

This book was released on 2022-12-02 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural toxins are toxic compounds that are naturally produced by living organisms. These toxins are not harmful to the organisms themselves, but they may be toxic to other creatures, including humans, when eaten. These chemical compounds have diverse structures and differ in biological function and toxicity. Some toxins are produced by plants as a natural defense mechanism against predators, insects, or microorganisms, or as a consequence of infestation with microorganisms, such as mold, in response to climate stress (such as drought or extreme humidity). Well-known groups of natural toxins of plant origin are: cyanogenic glycosides, pyrrolizidine alkaloids, furocoumarins, lectins, and glycoalkaloids. These plant-origin natural toxins can cause a variety of adverse health effects and pose a serious health threat to both humans and livestock. Analysis of Naturally Occurring Food Toxins of Plant Origin is divided into three sections that provide a detailed overview of different classes of food toxins that are naturally found in plants, including various analytical techniques used for their structural characterization, identification, detection, and quantification. This book provides in-depth information and comprehensive discussion over quantitative and qualitative analysis of natural toxins in plant-based foods. Key Features: • Provides a detailed overview of different classes of natural toxins found in plants. • Explains how IR, NMR, and mass spectrometry are utilized in characterization and identification. • Describes applicability of HPLC, LC-MS, GC-MS, and HPTLC techniques for detection and quantification. • Discusses progress in the field related to capillary electrophoresis, ELISA, and biosensors for quantitative application of these techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The prevalence of naturally occurring toxins in plant and animal foods represents one of the most significant food safety issues, drawing the attention of both scientists and regulators alike. This unexplored area related to food quality is indeed a big concern for consumers, various regulatory authorities, and food industries. Apart from essential nutrients, several food crops are capable of producing a vast array of nonnutritious secondary metabolic products. These toxins produced as secondary metabolites have the potential to exhibit both beneficial and deleterious effects in both human beings and animals. Nevertheless, there has been huge progress in agricultural practices and food processing technologies, but still the number of nonnutritive substances and naturally derived toxins persist in our diet. Handbook of Plant and Animal Toxins in Food: Occurrence, Toxicity, and Prevention, focuses on various selected toxins in foods derived from plants as well as animals. The prominent plant toxins include solanine and chaconine, mushroom toxins, phytates, tannins, oxalates, goitrogens, gossypol, phytohemagglutinins, erucic acid, saponins, cyanogenic glycosides, enzyme inhibitors, BOAA (lathyrogens), toxic amino acids and toxic fatty acids. The prominent animal toxins covered in the book include various seafood toxins, shellfish toxins and biogenic amines. Key Features: Presents complete information about a plethora of toxins Provides quick and easy access to data on major plant and animal toxins Covers distribution of toxins in the plant and animal kingdom Provides comprehensive information on chemistry, safety and precautions of each toxin Commencing with a brief introduction of food toxins, this book is designed in such a way that the readers will be introduced to toxicity, safety and occurrence of each toxin selected. It also discusses the in-depth detailed information on food poisoning and its prevention. The book will also shed light on foodborne illness associated with toxins. The primary audience for this work will be food scientists, food toxicologists, university scholars and college students. Furthermore, the book will be of immense help for public health officials, pharmacologists, and food safety officers who are involved with enforcing regulations meant to ensure the safety of a particular food

Available in PDF, EPUB and Kindle. Book excerpt: Cyanogenic glycosides are natural phytotoxins produced by over 2000 plant species, many of which are consumed by humans. The important food crops that contain cyanogenic glycosides include cassava (Manihot esculenta), sorghum (Sorghum bicolor), cocoyam (Colocasia esculenta L. and Xanthosoma sagittifolium L.), bamboo (Bambusa vulgaris), apple (Malus domestica), and apricot (Prunus armeniaca). Cyanogenic glycosides and their derivatives have amino acid-derived aglycones, which spontaneously degrade to release highly toxic hydrogen cyanide (HCN). Dietary cyanide exposure has been associated with several health challenges such as acute cyanide poisoning, growth retardation, and neurological disorders. This chapter will introduce general cyanogenesis principles, highlight major food plants with lethal cyanide levels, and provide epidemiological-based health conditions linked to cyanide intake. Furthermore, strategies for elimination of cyanogens from food crops, such as processing technologies, will be discussed. Finally, the chapter will analyze the role of cyanogenic plants in ensuring food security among resource-poor communities.

Available in PDF, EPUB and Kindle. Book excerpt: Toxic Constituents of Plant Foodstuffs focuses on toxic substances in foods of plant origin, including protease inhibitors, hemagglutinins, goitrogens, cyanogens, saponins, gossypol, lathyrogens, and allergens. The book also considers adventitious toxic factors in processed foods and miscellaneous toxic factors such as stimulants and depressants, hypoglycemic agents, toxic amino acids, metal-binding constituents, and hepatotoxins. This volume is organized into 13 chapters and begins with an overview of protease inhibitors, including their distribution in the plant kingdom, physical and chemical properties, and mechanism of interaction with proteases. The next chapters focus on the adventitious introduction of toxic factors into processed plant foods; the inactivation of the trypsin inhibitor and hemagglutinin found in legumes by cooking; and the extraction of a nontoxic, edible starch from cycads. The reader is also introduced to lathyrism, the toxicity of agglutinins, occurrence of goitrogens in thioglucoside-containing plants, and dietary sources of cyanogen. This book will be of interest and value to food scientists who are concerned with the safety of food supply and public health officials tasked with enforcing regulations necessary to ensure the safety of a particular food.

This book was released on 2020-09-04 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food, by nature, is a biological substrate and is therefore capable of supporting the growth of microbials that are potential producers of toxic compounds. Among them mycotoxins, marine biotoxins, plant toxins, cyanogenic glycosides, and toxins occurring in poisonous mushrooms pose not only a risk to both human and animal health but also impact food security and nutrition by reducing people's access to healthy food. This book collects some of the recent key improvements of analytical methodologies for the detection of natural toxins and their metabolites in food, and highlights the challenges yet to be resolved. Special emphasis is given to emerging or less-investigated toxins, to provide the scientific community with new tools and/or data supporting a better understanding of related food safety issues.
