Additives have been used in the food sector for centuries, aiming to maintain or improve food quality in terms of freshness, appearance, texture and taste. Most food additives are synthetic chemical compounds classified as antioxidants, antimicrobials, colorants and sweeteners. In the last decades, several synthetic food additives have been correlated with adverse reactions in humans, which has caused the safety of synthetic food additives to be reviewed and discussed by international organizations. At the same time, there is increasing consumer demand for more natural and environmentally friendly food products and additives. Therefore, synthetic food additives have been replaced with natural food additives. Although the use of natural additives is a hot topic in food science, to date no book has systematically reviewed the application of natural additives in food products. Natural additives in foods presents an exhaustive analysis of the most recent advances in the application of natural additives in the food sector. Covering natural antioxidants, antimicrobials, colorants and sweeteners, this text also focuses on unconventional sources of natural additives, valorization and toxicological aspects, consumer attitudes and regulatory aspects. The main applications of natural antioxidants are fully covered, including polyphenols, ascorbic acid, carotenoids, tocopherols and proteins. Natural antimicrobial applications from polyphenols and essential oils to poly-L-Lysine are analyzed, as are natural colorants like anthocyanins, annatto, betalains and paprika. The encapsulation, trapping, and adsorption of natural additives are studied, and consumer perceptions and preferences are major focuses. Researchers will find up-to-date regulatory specifics for the United States and European Union. For any researcher in need of an expansive single source containing all relevant and updated information for the use of natural additives in foods, this book is a much needed addition to the field.

Mycotoxins are the metabolites of fungus and are reported to contaminate nearly 25% of the food produced worldwide. The mycotoxins of most significance are the aflatoxins due to their severe health implications and their prevalence in food commodities on a larger scale. Aflatoxins are produced by certain species of fungi the most prominent among which are Aspergillus flavus, A. parasiticus and A. nominous. Food commodities of African and South Asian countries are especially reported to have aflatoxins well beyond the allowable limits but due to the global trade of food commodities developed countries are also prone towards the perils of aflatoxins. Moreover, climate changes may have a substantial impact on the distribution and global prevalence of aflatoxins in the near future. The International Agency for Research on Cancer (IARC) has classified the aflatoxins as group 1 category carcinogen. Aflatoxins are also reported as teratogenic, mutagenic, growth retardant, immunosuppressant and may also cause nervous system and reproductive system disorders. Preventive approaches involving good manufacturing from "farm to fork" are the major focus of the current food industry. The aim of our book is to provide readers with the most recent data and up-to-date studies from aflatoxins research, with specific focuses on (i) the impact of aflatoxins on human health, (ii) new approaches by the researchers from different parts of the world to degrade aflatoxins and (iii) potential preventive approaches that can significantly lessen the burden of aflatoxins in food products

Most bioactive compounds have antioxidant activity, particularly tocochromanols, phenolics (flavonoids and phenolic acids), methylxantines and capsaicinoids. Some of these compounds have also other properties important for human health. For example, vitamin E protects against oxidative stress, but it is also known for its "non-antioxidant" functions, including cell signalling and antiproliferation. Selenium compounds and indoleamins are the components of the antioxidant enzymes. Selenium makes vitamin E acquisition easier and controls its physiological functions. In taking part in enzymatic reactions and protecting the cell against free radicals, selenium shows immunomodulative, antiphlogistic, and antiviral activity. Capsaicinoids possess not only antioxidant, but also antibacterial, analgesic, weight-reducing and thermoregulation properties. Studies have also demonstrated their gastroprotective and anticancer properties. Analytical Methods in the Determination of Bioactive Compounds and Elements in Food explores both the influence of particular compounds on human health and the methods used for their determination. Chapters describe various aspects of food and plant analysis, including chromatographic and non-chromatographic approaches as well as hyphenated techniques. Readers of this book will gain a comprehensive understanding of the important groups of bioactive compounds relevant to human health.

Increased oxidative stress due to the production of excessive amounts of free radicals along with the effects of chronic inflammation plays a major role in the initiation and progression of most chronic diseases. In addition, increased release of glutamate plays a central role in the pathogenesis of various disorders. This second edition of Micronutrients in Health and Disease proposes a novel concept that in order to simultaneously and optimally reduce oxidative stress, chronic inflammation, and glutamate, it is essential to increase levels of antioxidant enzymes as well as levels of dietary and endogenous antioxidant compounds at the same time. This is accomplished by activating the Nrf2 pathways and by increasing the levels of antioxidant compounds and B-vitamins through supplementation. This book proposes a mixture of micronutrients that achieves this above goal. The mixture of micronutrients together with modification in diet and lifestyle may reduce the risk of chronic diseases and in combination with standard care, may improve the management of these diseases. KEY FEATURES * Provides evidence in support of the idea that increased oxidative stress, chronic inflammation, and glutamate are involved in the pathogenesis of chronic diseases. * Contains three new chapters on Huntington's disease, Autism spectra, and Prion disease. * Discusses the role of microRNAs in the pathogenesis of chronic diseases. * Presents information on regulation of the expression of microRNAs by reactive oxygen species and antioxidants. Micronutrients in Health and Disease, Second Edition serves as a valuable resource for those seeking to promote healthy aging and prevent and improved management of chronic diseases.

In the ongoing effort to combat global climate catastrophe, animal agriculture has long been a subject of contention. On the one hand, most agree that across the world increasing meat and dairy consumption are accelerating anthropogenic climate change. On the other hand, proponents of the livestock industry argue that modern advancements reduce greenhouse gas emissions from efficient livestock production to negligible quantities. Some even maintain that grass-based livestock production has a net positive impact on the environment, due to the carbon sequestration caused by grazing. Whom are we to believe? This book shows us that the answer is not so clear-cut. Beginning with the implications of the UN's Livestock's Long Shadow report, it breaks down the blind spots and highlights the insights of the most prominent pro-meat arguments, as well as of the push for a global switch to vegetarianism. While advances in efficiency might reduce greenhouse gas emissions per unit of meat or milk produced, attendant decreases in cost can enable overconsumption and thus produce more waste. And while carbon sequestration is beneficial, it is not a reliable cure-all for the industry. Due to the economics of farming, however, eliminating meat consumption may not even reduce emissions at all. The truth about livestock production is much more nuanced but, luckily, also far more holistic. The future of agricultural policy will have to take into consideration factors such as human health and economics, as well as climate. Eschewing ideology for empirical rigor, this book paves an actionable path forward for both consumers and producers, offering unique solutions for each livestock system and simple, everyday adjustments for the average omnivore.

This book addresses the shelf life of foods, a key factor in determining how food is distributed and consequently where and when different food products are available for consumption. Shelf life is determined by several factors, including microbiological, chemical, physical, and organoleptic deterioration. Often these factors are interrelated and interdependent. The editors of this volume focus specifically on the microbial factors related to shelf life of perishable foods and food commodities. This allows for more detailed coverage of foodborne bacterial pathogens and spoilage microorganisms of concern. The initial part of the book covers the why and how of shelf life determination as well as the specific microbial pathogens and spoilage microorganisms of concern for perishable foods. Contributors address topics such as the techniques utilized for determination of shelf life, the frequency of shelf life testing for different products, the interpretation of data to make shelf life determinations, and management of shelf life of food products from the perspective of the food producer, distributor, retailer, and regulator. Three key areas impacting shelf life are addressed in detail: sanitation, processing, and packaging. The sanitation chapter explains the necessary components of cleaning and sanitizing to assure a hygienic processing environment and why that is critical to shelf life control. Traditional processing procedures are reviewed and advanced processing technologies are explored. Materials used in food packaging and the utilization of traditional and activated food packaging by product type are covered in detail. The latter two chapters of the book delve into newer techniques of analysis and explore the microbiome of food products. Implications of microbial ecology and microbial quantification in food products are discussed in chapters on genomics and in the changing dogma of meat shelf life. The primary audience for this work includes food industry quality and food safety technicians, managers, directors, and executives responsible for shelf life. Academicians and governmental researchers involved in research and teaching about food safety and quality will also find the material relevant and useful.
