Healthier foods have received unprecedented attention in the last couple of years. Different units of food processing assure physicochemical stability and microbiological safety, and simultaneously result in significant modifications in the composition and structure of food matrices, followed by the variations in nutrition and health properties such as intestinal bioaccessibility and bioavailability of functional small molecules of interests. Therefore, the correlation between extrinsic processing factors and composition-structure-properties response has been one of the focuses of food science research, largely relying on food matrices and the applied technique types. In this regard, thermal conditions receive the most attention considering its generalization and high applicability. For current food industries, multiple processing techniques, process strategies, and the combined approaches have been largely proposed, e.g., the uses of emerging external fields including sound, electric and plasma fields. Resultantly, the presence of new-type physico-chemical interaction behavior of minor/major components and composition-structure-property modifications exerted by emerging processing methods or patterns require more elaborate characterization, analysis and summarization over the response of quality, nutritional and health properties of final products. This Research Topic encourages researchers to submit Original Research and Review articles highlighting the roles of processing-induced physico-chemical modifications and interaction behavior of different intrinsic food components, particularly at molecular levels, in regulating the changes of quality, storability, nutrition and health characteristics of food products. Researchers working on the development of analysis, evaluation and characterization techniques to tackle issues related to complicated network of chemical changes, microstructural imaging and modeling as well as in vitro / in vivo nutrition effects are also encouraged to contribute. Healthier food can be obtained via food re-formulation and microstructure designing associated with processing parameters, relying on the accumulation of knowledge about the correlation between food structure, gastrointestinal fate of nutrients and satiety response. This Research Topic welcomes original research articles, reviews, systematic reviews, technology and code, and methods, covering, but not limited to, the following themes: - Novel characterization techniques applied to monitor processing effects; - Metabolic and omic characterization of bio-processing foods; - Characterization of composition-structure-property relation of newly developed food resources during processing; - Chemical modifications of food components (e.g., protein, lipid, carbohydrates, phytochemicals, etc.) during traditional thermal processing and emerging nonthermal processing processes or the combined patterns; - Effects of the chemical modifications during processing on nutrition and health; - Interaction between food components as affected by processing parameters, as well as its effects on nutritional properties (e.g., digestibility, bioaccessibility, bioavailability, etc.); - Food safety challenges and strategies for processing and preservation processes.

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.

Water, saccharides, proteins, lipids, minerals, colorants, and additives all contribute to the nutritional value and sensory properties of food. During post harvest storage and processing, these components change and the extent and nature of change depends on the chemical properties of the compounds themselves. Knowledge of the chemistry and biochemistry behind food components and their behavior in the face of various stressors aids in making the right decisions for controlling the rate of beneficial and undesirable reactions, selecting optimal storage and processing parameters, and the best use of food raw materials. Chemical and Functional Properties of Foods, Third Edition draws from the personal research and teaching experience of experts from universities and research institutions around the world. Beginning with an examination of food components both natural and added, this volume, like its predecessors, details the role of chemical compounds in the structure of raw materials and the formation of different attributes of food quality. New in the third edition— The rheological behavior and the interactions among different food constituents The interactions of food components in storage and processing and their effects on product quality The safety and biological aspects of foods Discussions of allergenic activity, pre- and probiotics, children’s nutrition, and the effect of food on mood and health The biological effects of food components on human health and chronic disease Complete revisions of nearly every chapter with references to the most current publications Emphasizing the role of the chemical properties of different foods and the reactions that take place during processing and storage, Chemical and Functional Properties of Foods, Third Edition reviews the current knowledge of the resulting effect on the sensory, nutritional, and safety aspects of food quality.
