Nano- and Microencapsulation for Foods by Hae-Soo Kwak Pdf

Today, nano- and microencapsulation are increasingly being utilized in the pharmaceutical, textile, agricultural and food industries. Microencapsulation is a process in which tiny particles or droplets of a food are surrounded by a coating to give small capsules. These capsules can be imagined as tiny uniform spheres, in which the particles at the core are protected from outside elements by the protective coating. For example, vitamins can be encapsulated to protect them from the deterioration they would undergo if they were exposed to oxygen. This book highlights the principles, applications, toxicity and regulation of nano- and microencapsulated foods. Section I describes the theories and concepts of nano- and microencapsulation for foods adapted from pharmaceutical areas, rationales and new strategies of encapsulation, and protection and controlled release of food ingredients. Section II looks closely at the nano- and microencapsulation of food ingredients, such as vitamins, minerals, phytochemical, lipid, probiotics and flavors. This section provides a variety of references for functional food ingredients with various technologies of nano particles and microencapsulation. This section will be helpful to food processors and will deal with food ingredients for making newly developed functional food products. Section III covers the application of encapsulated ingredients to various foods, such as milk and dairy products, beverages, bakery and confectionery products, and related food packaging materials. Section IV touches on other related issues in nano- and microencapsulation, such as bioavailability, bioactivity, potential toxicity and regulation.

Intensification of Biobased Processes by Andrzej Gorak,Andrzej Stankiewicz Pdf

In recent years bioprocessing has increased in popularity and importance, however, bioprocessing still poses various important techno-economic and environmental challenges, such as product yields, excessive energy consumption for separations in highly watery systems, batch operation or the downstream processing bottlenecks in the production of biopharmaceutical products. Many of those challenges can be addressed by application of different process intensification technologies discussed in the present book. The first book dedicated entirely to this area, Intensification of Biobased Processesprovides a comprehensive overview of modern process intensification technologies used in bioprocessing. The book focusses on four different categories of biobased products: bio-fuels and platform chemicals; cosmeceuticals; food products; and polymers and advanced materials. It will cover various intensification aspects of the processes concerned, including (bio)reactor intensification; intensification of separation, recovery and formulation operations; and process integration. This is an invaluable source of information for researchers and industrialists working in chemical engineering, biotechnology and process engineering.

Characterization of Liquids, Dispersions, Emulsions, and Porous Materials Using Ultrasound by Andrei S. Dukhin,Philip J. Goetz Pdf

Characterization of Liquids, Dispersions, Emulsions and Porous Materials Using Ultrasound, Third Edition, presents a scientific background for novel methods of characterizing homogeneous and heterogeneous liquids (dispersions, emulsions, and gels) as well as porous materials. Homogeneous liquids are characterized in rheological terms, whereas particle-size distribution and zeta potential are parameters of heterogeneous liquids. For porous materials, porosity, pore size, and zeta potential are output characteristics. These methods are based on ultrasound, which opens an opportunity for simplifying the sample preparation by eliminating dilution. This in turn, makes measurements faster, easier, precise, suitable for accurate quality control, PAT, and formulation of complex systems. This book provides theoretical background of acoustics, rheology, colloid science, electrochemistry, and other relevant scientific fields, describing principles of existing instrumentation and, in particular, commercially available instruments. Finally, the book features an extensive list of existing applications. Presents a theoretical multi-disciplinary background of several new ultrasound analytical techniques in one place Validates the theoretical basis of several new analytical techniques Compares the efficiency and applications of various ultrasound techniques Lists many ultrasound applications in colloid chemistry Contains an extensive bibliography on this multidisciplinary topic

Skin Permeation and Disposition of Therapeutic and Cosmeceutical Compounds by Kenji Sugibayashi Pdf

This book reviews skin permeation and disposition of chemical compounds. Skin is utilized as an administration site for transdermal drug delivery systems, topical drug formulations, cosmeceuticals, and cosmetics. Their usefulness is closely related to the permeation and disposition of entrapped active ingredients through and into the skin. Skin permeation, disposition, and metabolism of chemicals are first summarized in the general introduction. Then primary topical formulations are explained in the second part, “Basic Formulations Applied to Skin”. The explanation for the active compounds and formulations are of the most important parts required to fabricate these formulations. Skin absorption of chemicals is generally much lower than oral and the other mucosal absorptions, so that skin-penetration enhancement is a key issue to have good formulations topically applied. Part 3 presents “Skin Penetration Enhancement”. In addition, Part 4, “Selection of Topically Applied Chemical Candidates”, deals with selection methods of topically applied ingredients for transdermal drug delivery systems, topical drug formulations, cosmeceuticals, and cosmetics. Parts 5 and 6, “Safety Assessment of Topically Applied Compounds“ and “Experimental Methods of Skin Permeation“, respectively, show safety issues and experimental methods for topical formulations. The final part consists of comments on therapeutic and cosmetic formulations by medical doctors and pharmacists. Their comments are especially helpful for pharmaceutical and cosmetic researchers who study dermatopharmacokinetics and topical formulations. This volume is particularly useful for those working in R&D, graduate students, and educators in the area of pharmaceutics, cosmetic sciences, dermatological sciences, pharmacology, toxicology, biopharmacy, pharmacokinetics, physical pharmacy, chemical engineering, and related fields.

Characterization of Liquids, Nano- and Microparticulates, and Porous Bodies using Ultrasound by Andrei S. Dukhin,Philip J. Goetz Pdf

Two key words define the scope of this book: 'ultrasound' and 'colloids'. Historically, there has been little real communication between practitioners in these two fields. Although there is a large body of literature devoted to ultrasound phenomenon in colloids, there is little recognition that such phenomena may be of real importance for both the development and applications of colloid science. On the other side, colloid scientists have not embraced acoustics as an important tool for characterizing colloids. The lack of any serious dialogue between these scientific fields is the biggest motivation behind this book. Covers in detail this multidisciplinary field combining acoustics, electroacoustics, colloid science, analytical chemistry and rheology Provides a bibliography with more than 1,000 references Presents theories and their experimental verification, as well as analysis of the methods and hardware pertaining to applications such as pharmaceuticals, ceramics, and polymers
