This Brief presents the main aspects of the response functions theory (RFT) for molecular solutes described within the framework of the Polarizable Continuum Model (PCM).
The enzymatic polymerization of phenolic compounds has been generating interest in several fields such as food, cosmetics, and pharmaceuticals. In this title, these compounds are employed for their antioxidant properties; however, their use is limited by their low solubility and thermal stability.
This book discusses a major issue in the food contact materials industry: non-intentionally added substances (NIAS), and their impact on PET-bottled water.
In this work, the synthesis of several materials are studied: nanoclay-cement nanocomposite, calcined nanoclay-cement nanocomposite, untreated & treated hemp fabric-reinforced cement composite, hemp fabric-reinforced nanoclay-cement nanocomposite and treated hemp fabric-reinforced nanoclay-cement nanocomposite.
This book provides the tools to understand the issues related to bio-based concretes using lime as binder. Themes covered include specific properties of lignocellulosic aggregates (density, porosity, size distribution, water absorption, microstructure, soluble components under alkaline conditions), hardening of lime-based binders by carbonation and hydration (natural and curing processes) and microstructure of the binder in the vicinity of aggregates (dense or porous interphase). The mechanical (uniaxial and triaxial compression) and insulating properties of the relatively well-known hemp concretes and the novel rice husk concretes are also reviewed. Finally, a detailed and comprehensive description of the tools and methodologies that make it easier the design of such bio-based concretes is discussed. Written for students as well as researchers, this book is aimed at individuals working in both academic and industrial fields.
In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications.
The book describes the pretreatment of lignocellulosic biomassfor biomass-to-biofuel conversion processes, which is an important step inincreasing ethanol production for biofuels.
They emphasize the great efforts that have been made to synthesize new bio-based polymers or additives or to replace glass fibers by natural fibers in composites. The flame retardancy of biobased polymers, the flame retardancy of natural fibers composites, and the synthesis and efficiency of biobased flame retardants.
This Brief reviews thermal processes in the food industry - pasteurization, sterilization, UHT processes, and others. In addition, historical preservation techniques - smoking, addition of natural additives, irradiation, etc. - are compared with current industrial systems, like fermentation, irradiation, addition of food-grade chemicals.
Advances in Ultrasound Technology for Environmental Remediation reviews the fundamentals of ultrasound technology and the state of the art developments in "ultrasound-based free radical generation" in environmental remediation and pollution prevention.
This book focuses on bioconversion of lignocellulosic residues into single-cell protein, which offers an alternative to conventional proteins (such as soybean meal, egg protein or meat protein in animal feed) that is not affected by the climate.
Historically, the reaction was used in chemical analysis and to highlight the nature of chemical reactions, the laws of chemistry, models and theories of chemistry, chemical nomenclature, mathematics and data analysis, and instrumentation, which are important ingredients of what one might call the nature of chemistry.
This book explains the role of food-oriented (or 'food-centric') quality system standards in the modern food and beverage industry. It discusses food safety schemes based on the international norm ISO 9001 and the "Hazard Analysis and Critical Control Points" approach, and also introduces the new Global Standard for Food Safety (GSFS) and the International Featured Standard (IFS, 7th ed.), outlining standardization for international equivalence (while maintaining the necessary flexibility and independence - which is not always easy an easy task).Providing selected specific examples, it examines the problems of chemical additives and possible cross-contaminations between different production lines, as well as adequate reactions to and handling of intentional adulterations. In addition, it includes a chapter focusing on quality audits and technical data sheets in the food industry, and a final chapter describing the certification of food-grade lubricants in the food industry, especially with regard to allergenic substances.
This book describes the consequences of an increased demand for food for human consumption for the global food industry. Chapter two discusses how the expansion of cropland and pastures to meet the rising demand for food is damaging the environment, while chapter three examines the impact of bee viruses on food crops and production.
This Brief is devoted to clean drinking water, which is (one of) the most important asset(s) in the food and beverage industry. In the present time of increasing water scarcity in many areas of the world, supply of clean water especially in the production and packaging chain of foods and beverages, is a crucial issue.
