Book Description
Plants are the most important renewable source of feedstock for polymeric materials. They are a resource of monomers and macromolecules after the appropriate chemical treatment. By analogy with the petrochemistry industry, plant macromolecules are depolymerized into simpler units which are generally chemically modified and re-bound to produce new polymers. The properties of these polymers are usually tailored by small chemical changes in their molecular structure, or by the polymerization of plant monomers with other molecules. Another interesting strategy for the formation of polymeric materials is the direct use of plant macromolecules in the form of blends, composites, grafted polymers, multilayer systems, etc. The interactions and assemblies of the different components allow the control of the final features of such materials. Traditionally, polysaccharides, with cellulose as the main protagonist, have been the most used substances. However, as consequence of a growing demand of functional plastics, other plant macromolecules, habitually considered wastes, have started to become valuable raw materials. Lignin and plant proteins (mainly, soy protein, wheat gluten, and zein) are classical examples. Also, suberin has been highlighted in this field. Other plant polymers such as the cutin and the sporopollenin are promising alternatives. Furthermore, other minority plant polymers, e.g. cutan or algaenan, could be potential sources of materials. The different chemistry, structure, intrinsic properties and functions of these macromolecules in the plants are a strong inspiration for the development of novel and interesting polymeric materials. Here, in this Research Topic, we welcome the submission of manuscripts related to the production, extraction, processability, synthesis, characterization and applications of non-polysaccharides plant materials.

Book Description
"In the search for sustainable materials, natural polymers present an attractive alternative for many applications compared to their synthetic counterparts derived from petrochemicals. The two volume set, Natural Polymers, covers the synthesis, characterisation and applications of key natural polymeric systems including their morphology, structure, dynamics and properties. Volume one focuses on natural polymer composites, including both natural and protein fibres, and volume two on natural polymer nanocomposites. The first volume examines the characterization, life cycle assessment and new sources of natural fibres and their potential as a replacement for synthetic fibres in industrial applications. It then explores the important advancements in the field of wool, silk, spidersilk and mussel byssus fibres. The second volume looks at the properties and characterization of cellulose, chitosan, furanic, starch, wool and silk nanocomposites and the potential industrial applications of natural polymer nanocomposites"-- Provided by publisher.

Book Description
Seaweed Polysaccharides: Isolation, Biological, and Biomedical Applications examines the isolation and characterization of algal biopolymers, including a range of new biological and biomedical applications. In recent years, significant developments have been made in algae-based polymers (commonly called polysaccharides), and in biomedical applications such as drug delivery, wound dressings, and tissue engineering. Demand for algae-based polymers is increasing and represent a potential—very inexpensive—resource for these applications. The structure and chemical modification of algal polymers are covered, as well as the biological properties of these materials – including antithrombic, anti-inflammatory, anticoagulant, and antiviral aspects. Toxicity of algal biopolymers is also covered. Finally, the book introduces and explains real world applications of algal-based biopolymers in biomedical applications, including tissue engineering, drug delivery, and biosensors. This is the first book to cover the extraction techniques, biomedical applications, and the economic perspective of seaweed polysaccharides. It is an essential text for researchers and industry professionals looking to work with this renewable resource. - Provides comprehensive coverage of the research currently taking place in biomedical applications of algae biopolymers - Includes practical guidance on the isolation, extraction, and characterization of polysaccharides from sustainable marine sources - Covers the extraction techniques, biomedical applications, and economic outlook of seaweed polysaccharides

Book Description
Food--how we produce, prepare, share and consume it--is fundamental to our wellbeing. It also connects the human body to the complex and dynamic systems of our environment. This is more significant than ever before in human history, as climate change and increasing population impact on global ecosystems. This fourth edition of Food and Nutrition has been completely rewritten to reflect an ecosystems approach to human health. It is shaped around four dimensions of human nutrition: biology, society, environment and economy. Food and Nutrition provides a comprehensive overview of food components and the biochemistry of foods and digestion. It outlines nutrition needs at different life stages, dietary disorders, and social and cultural influences on food selection and consumption. It also explores the increasing influence of technology on agriculture and food preparation, and recent research into intergenerational nutrition and nutrigenomics. At every stage it points to how you can impact your own health and the health of others as a global citizen and as a health or other food-system-related professional. Extensively illustrated with informative graphs, diagrams and data, and with examples, glossaries and reflective exercises, Food and Nutrition is the ideal introduction to the field of nutrition and dietetics for the 21st century, and a valuable professional reference for early career dietitians.
