A food allergen has the ability to first elicit an IgE response, and then, on subsequent exposures, a clinical response to the same or similar protein. How harmless food protein becomes recognized by the mucosal immune system as an allergen remains an open question and more data are needed to explain how regulatory mechanisms of the mucosal immune system fail and result in allergic sensitization to dietary antigens. Some biochemical characteristics associated with food allergens, such as the presence of multiple, linear IgE-binding epitopes and the resistance of the protein to digestion and processing, seem to predominate among food allergens. Digestion susceptibility of food allergens that sensitize via the gastrointestinal tract and stability to food processing conditions are inherently related to protein structural features. Thereby, physiological changes in the digestion process, pathological conditions affecting digestion, as well as procedures and food processing conditions that affect protein structure may all have a profound effect on the sensitizing potential and allergenicity of food proteins. In addition, signals coming from the diet and micro biome can modulate regulatory mechanisms of the mucosal immune system and influence mucosal immunity and intestinal barrier function. The detection of allergenic ingredients in food products has received increased attention from the food industry and legislative and regulatory agencies over recent years. This has resulted in the improvement of applied safety measures that provide protection for food-allergic consumers and development of sensitive and highly specific analytical methods of food allergens detection. Food allergy is an important and common health issue and therefore there is a need to characterize the sensitizing potential of newly introduced proteins in genetically engineered foods. A combination of in vitro and in silico methods provide information that contributes to safety assessment. Suitable in vivo models may provide a more holistic assessment of allergenic potential of novel food proteins.

Over three editions, this book described the contents of food raw materials and products, the chemistry/biochemistry of food components, as well as the changes occurring during post-harvest storage and processing affecting the quality of foods. The fourth edition of Chemical and Functional Properties of Food Components discusses the role of chemical compounds in the structure of raw materials and the formation of different attributes of food quality, including nutritional value, safety, and sensory properties. This new edition contains four new chapters: “Non-Protein Nitrogenous Compounds”; “Prooxidants and Antioxidants in Food”; “Non-Nutritive Bioactive Compounds in Food of Plant Origin”; and “Analytical Methods Used for Assessing the Quality of Food Products.” These chapters have been included because new research results have brought increasing knowledge on the effect of non-protein nitrogenous compounds, especially bioactive peptides, nucleic acids, and biogenic amines on the biological properties of foods; the role of natural and added prooxidants and antioxidants in the processing and biological impact of foods; numerous beneficial and harmful effects of bioactive components of plant foods; and new systems for control of food composition and the safety of foods. Features: • Stresses the effect of the chemical/biochemical reactions on the selection of optimum parameters of food processing without presenting details of the technological processes • Describes naturally occurring elements and compounds as well as those generated during food handling in view of health hazards they may bring to consumers • Discusses the risks and benefits of reactions occurring during food handling The knowledge of the chemistry and biochemistry of the components and their interactions presented in this book aids food scientists in making the right decisions for controlling the rate of beneficial and undesirable reactions, selecting optimal storage and processing parameters, as well as the best use of food raw materials.

Much has been written about food allergies in scientific journals and in the lay press, but Food Allergies: Processing Technologies for Allergenicity Reduction approaches the issue of food allergies from an industrial processing rather than a clinical perspective. Indeed, industrial food processing technologies can have many beneficial effects to obtain various food products and to preserve foods from physical, chemical and microbiological alterations. However, processing technologies, including thermal and non‐thermal technologies, can also alter the allergenic properties of food proteins. This book provides an authoritative source of information on the relationship between food processing technologies and food allergens with a greater variety of studied allergens including peanuts, tree nuts, cow’s milk, eggs, sesame, lupine, soy, wheat, mustard, mushroom, fish and shellfish, as well as the importance of processing these when producing hypoallergenic foods. Key Features: Presents food allergies with recent advances and statistics concerning prevalence, physiopathologic mechanism, diagnosis and anaphylaxis Discusses food allergies in the food industry and investigates the effect of processing on allergenicity of foods during manufacturing Provides food processing and promising technologies to produce hypoallergenic food with high quality Covers the allergenic effect of different food additives with an investigation of cross‐reaction risks This unique book is an indispensable guide for allergic patients, production managers, scientists and nutritionists within the food industry as well as covering a range of critical topics in this area for all those concerned with understanding and managing food allergies.

Over the past 20 years, public concerns have grown in response to the apparent rising prevalence of food allergy and related atopic conditions, such as eczema. Although evidence on the true prevalence of food allergy is complicated by insufficient or inconsistent data and studies with variable methodologies, many health care experts who care for patients agree that a real increase in food allergy has occurred and that it is unlikely to be due simply to an increase in awareness and better tools for diagnosis. Many stakeholders are concerned about these increases, including the general public, policy makers, regulatory agencies, the food industry, scientists, clinicians, and especially families of children and young people suffering from food allergy. At the present time, however, despite a mounting body of data on the prevalence, health consequences, and associated costs of food allergy, this chronic disease has not garnered the level of societal attention that it warrants. Moreover, for patients and families at risk, recommendations and guidelines have not been clear about preventing exposure or the onset of reactions or for managing this disease. Finding a Path to Safety in Food Allergy examines critical issues related to food allergy, including the prevalence and severity of food allergy and its impact on affected individuals, families, and communities; and current understanding of food allergy as a disease, and in diagnostics, treatments, prevention, and public policy. This report seeks to: clarify the nature of the disease, its causes, and its current management; highlight gaps in knowledge; encourage the implementation of management tools at many levels and among many stakeholders; and delineate a roadmap to safety for those who have, or are at risk of developing, food allergy, as well as for others in society who are responsible for public health.

Food antioxidants are of primary importance for the preservation of food quality during processing and storage. However, the status of food depends on a balance of antioxidants and prooxidants occurring in food. Food Oxidants and Antioxidants: Chemical, Biological, and Functional Properties provides a single-volume reference on the effects of naturally occurring and process-generated prooxidants and antioxidants on various aspects of food quality. The book begins with a general introduction to oxidation in food and then characterizes the main oxidants present in food, including enzymatic oxidants. Chapters cover oxidation potential, mechanisms of oxidation of the main food components (proteins and lipids), addition of exogenous oxidants during food processing, and the effects of physical agents such as irradiation, freeze-thawing, and high hydrostatic pressure during processing. The book also discusses the effects of oxidation on sensory characteristics of food components and analyzes how oxidation and antioxidants affect the nutritive and health-promoting features of food components. The text examines natural antioxidants in food, including lesser-known ones such as amino acids and polysaccharides, antioxidants generated in food as a result of processing, mechanisms of antioxidant activity, and measurement of antioxidant activity of food components. It explores the bioavailability of curcuminoid and carotenoids antioxidants and presents case studies on natural food antioxidants, presenting novel extraction methods for preservation of antioxidant activity. The final chapters address functional antioxidant foods and beverages as well as general ideas on the effects of food on the redox homeostasis of the organism.
