Familiar combinations of ingredients and processing make the structures that give food its properties. For example in ice cream, the emulsifiers and proteins stabilize partly crystalline milk fat as an emulsion, freezing (crystallization) of some of the water gives the product its hardness and polysaccharide stabilizers keep it smooth. Why different recipes work as they do is largely governed by the rules of physical chemistry. This textbook introduces the physical chemistry essential to understanding the behavior of foods. Starting with the simplest model of molecules attracting and repelling one another while being moved by the randomizing effect of heat, the laws of thermodynamics are used to derive important properties of foods such as flavor binding and water activity. Most foods contain multiple phases and the same molecular model is used to understand phase diagrams, phase separation and the properties of surfaces. The remaining chapters focus on the formation and properties of specific structures in foods - crystals, polymers, dispersions and gels. Only a basic understanding of food science is needed, and no mathematics or chemistry beyond the introductory college courses is required. At all stages, examples from the primary literature are used to illustrate the text and to highlight the practical applications of physical chemistry in food science.
Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.

In his thesis, Kiyoun Lee describes his studies into tandem and organocatalytic oxa-conjugate addition reactions for the synthesis of complex tetrahydropyrans (THP). Readers gain insight into the new methods Lee employs for the synthesis of biologically interesting natural products including (+)-leucascandrolide A, (+)-dactylolide, and (+/-)diospongin A. The reactions Lee investigates are applicable to a broad range of substrates and proceed with excellent stereoselectivity. Moreover, the methodologies allow the synthesis of a wide range of THP-containing compounds. The development of reactions, such as those discussed by Lee, has the potential to impact natural product synthesis, pharmaceutical development and chemical biology.
The role of theory in science was formulated very brilliantly by Max Planck: Experimenters are the striking force of science. The experiment is a question which science puts to nature. The measurement is the registration of nature's answer. But before the question is put to nature, it must be formulated. Before the measurement result is used, itmust be explained, i.e., the answer must be understood correctly. These two problems are obligations of the theoreticians. Chemical engineering is an experimental science, but theory permits us to formulate correct experimental conditions and to understand correctly the exp- imental results. The theoretical methods of chemical engineering for modeling and simulation of industrial processes are surveyed in this book. Theoretical chemical engineering solves the problems that spring up from the necessity for a quantitative description of the processes in the chemical industry. They are quite different at the different stages of the quantitative description, i.e., a wide circle of theoretical methods are required for their solutions. Modeling and simulation are a united approach to obtain a quantitative description of the processes and systems in chemical engineering and chemical technology, which is necessary to clarify the process mechanism or for optimal process design, process control, and plant renovation. Modeling is the creation of the mathematical model, i.e., construction of the mathematical description (on the basis of the process mechanism), calculation of the model parameters (using experimental data), and statistical analysis of the model adequacy.

"Microorganisms in Foods 8: Use of Data for Assessing Process Control and Product Acceptance" is written by the International Commission on Microbiological Specifications for Foods with assistance from a limited number of consultants. The purpose of this book is to provide guidance on appropriate testing of food processing environments, processing lines, and finished product to enhance the safety and microbiological quality of the food supply. Microorganisms in Foods 8 consists of two parts. Part I, Principles of Using Data in Microbial Control, builds on the principles of "Microorganisms in Foods 7: Microbiological Testing in Food Safety Management" (2002), which illustrates how HACCP and Good Hygienic Practices (GHP) provide greater assurance of safety than microbiological testing, but also identifies circumstances where microbiological testing may play a useful role. Part II, Specific Applications to Commodities, provides practical examples of criteria and other tests and is an updated and expanded version of Part II of "Microorganisms in Foods 2: Sampling for Microbiological Analysis: Principles and Specific Applications" (2nd ed. 1986). Part II also builds on the 2nd edition of "Microorganisms in Foods 6: Microbial Ecology of Food Commodities" (2005) by identifying appropriate tests to evaluation the effectiveness of controls.

Cellular plastics or plastic foams, also referred to as expanded or sponge plastics, generally consist of a minimum of two phases, a solid-polymer matrix and a gaseous phase derived from a blowing agent. The solid-polymer phase may be either inorganic, organic or organometallic. There may be more than one solid phase present, which can be composed of polymer alloys or polymer blends based on two or more polymers, or which can be in the form of interpenetrating polymer networks (I PNs) which consist of at least two crosslinked polymer networks, or a pseudo- or semi-1 PN formed from a combination of at least one or more linear polymers with crosslinked polymers not linked by means of covalent bonds. Other solid phases may be present in the foam in the form of fillers, either fibrous or other shaped fillers which may be of inorganic origin, e.g., glass, ceramic or metallic, or they may be polymeric in nature. Foams may be flexible or rigid, depending upon whether their glass- transition temperatures are below or above room temperature, which, in turn, depends upon their chemical composition, degree of crystallanity, and degree of crosslinking. Intermediate between flexible and rigid foams are semi-rigid or semi- flexible foams. The cell geometry, i.e., open vs. closed cell, size and shape, greatly affect the foam properties. This book is intended to be a source of practical up-to-date information on all types of plastic foams (cellular plastics) in current use, including the newer structural plastic foams. Elastomeric (rubber-like) foams are also considered. The book is intended primarily for those who require a nontheoretical, authoritative, easy-to-use handbook in the subjectarea. It should be of value to materials engineers, plastics fabricators, chemists, chemical engineers, and students. Recognized authorities have written several chapters and parts of chapters in their fields of expertise. The book is organized in such a way that information on a desired subject can be found rapidly. An unusual feature is a comprehensive listing of all known standardization documents (test methods, practices, and specifications), including some international standards. Each document includes a brief description of its contents.

In the respective chapters, an outline of the biology and function of the skin and its appendages, ie hair, teeth and nails, is given, followed by descriptions of the needs for products, their formulation and manufacture. In Part 2 there are seven chapters covering the knowledge required and the procedures to follow when marketing cosmetics. They are analytical methods, efficacy testing, emulsion theory, microbial control, legislation, safety and stability. Part 3 contains three chapters covering historical background, the perfuming of products and lastly the psychology of fragrance. This book provides a basic knowledge of "cosmetics" - a word which covers any product used to cleanse, protect or adorn the human body. It aims to serve as a valuable introduction and source of reference for all those involved in the cosmetics and toiletries industry, including suppliers of raw materials, manufacturers of finished products, R&D laboratories in industry and educational institutions as well as beauty clinics and schools.
Due to their unparalleled effectiveness and efficiency, polyfluorinated chemicals (PFC") "have become essential in numerous technical applications. However, many PFCs brought to market show limited biodegradability, and their environmental persistence combined with toxic and bioaccumulative potential have become a matter of concern in some instances. This volume highlights the synthesis of PFCs, focusing on substances with improved application and environmental properties, which are a challenge for synthetic chemists. Further, modern mass spectrometric techniques for the detection and identification of biotransformation products of PFCs are described. The sorption and leaching behavior of PFC in soil is also addressed in order to predict their fate in the environment. Several contributions discuss the monitoring of PFCs in European surface, ground and drinking waters, treatment options for PFC removal from drinking water, occurrence in food, and the human biomonitoring of PFCs.
