Book Description
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.

Book Description
Despite increasing knowledge of human nutrition, the dietary contribution to cancer remains a troubling question. Carcinogens and Anticarcinogens assembles the best available information on the magnitude of potential cancer riskâ€"and potential anticarcinogenic effectâ€"from naturally occurring chemicals compared with risk from synthetic chemical constituents. The committee draws important conclusions about diet and cancer, including the carcinogenic role of excess calories and fat, the anticarcinogenic benefit of fiber and other substances, and the impact of food additive regulation. The book offers recommendations for epidemiological and diet research. Carcinogens and Anticarcinogens provides a readable overview of issues and addresses critical questions: Does diet contribute to an appreciable proportion of human cancer? Are there significant interactions between carcinogens and anticarcinogens in the diet? The volume discusses the mechanisms of carcinogenic and anticarcinogenic properties and considers whether techniques used to evaluate the carcinogenic potential of synthetics can be used with naturally occurring chemicals. The committee provides criteria for prioritizing the vast number of substances that need to be tested. Carcinogens and Anticarcinogens clarifies the issues and sets the direction for further investigations into diet and cancer. This volume will be of interest to anyone involved in food and health issues: policymakers, regulators, researchers, nutrition professionals, and health advocates.

Book Description
Spices are obtained from natural sources, especially from plants, and are used in cooking food in whole or grounded forms mainly for imparting flavor, aroma, and piquancy. Besides their role in improving food quality, spices also have health benefits that are anticancer, antidiabetic, antimicrobial, antioxidant, hypolipidemic, analgesic, immunostimulant, and more. Spices are generally marketed in powder form, and their supply chain is very long and complicated, which is why they are particularly susceptible to adulteration at many points. The spice supply chain is considered to be moderately vulnerable and has an ineffective quality detection system in its final product, which is the main risk factor. There are many types of fraud nowadays related to spices such as adulteration, falsification, substitution, and inaccurate labeling. Analysis of Food Spices: Identification and Authentication provides an overview of spices of different categories, such as terpenes and terpenoids, oleoresins, alkaloids, and polyphenolics and flavonoids, as well as qualitative and quantitative guidelines for ensuring their quality and safety using modern analytical tools and techniques. The first section of the book discusses the overview, sources, and health benefits of important categories of spices such as terpenes and terpenoids (cardamom, cinnamon, clove, coriander, cumin, fennel), oleoresins (capsicum, ginger, nutmeg), alkaloids (black pepper, fenugreek), and polyphenolics and flavonoids (basil, turmeric, olive, saffron). In the second section, qualitative diagnostic features of spices are covered. In the third section, the roles of quantitative analytical techniques, such as HPLC, LC-MS, HPTLC, GC, and GC-MS, capillary electrophoresis (CE), and other recent techniques in the analysis of food spices, are also discussed. Each chapter concludes with a general reference section, which is a bibliographic guide to more advanced texts. Key Features Provides a detailed overview of different food spices of plant origin, and discusses their health benefits and uses of different analytical techniques in its quality control Explains how qualitative diagnostic features of food spices are utilized as quality control tools Describes applicability of analytical techniques like HPLC, LC-MS, GC-MS, HPTLC, and CE for quality control of food spices Emphasizes use of recent techniques such as proteomics, biosensors, and more in the analysis/quality control of food spices This book will provide important guidelines for controlling quality, safety, and efficacy issues related to food spices.
