Here is a new book that offers complete coverage of the most current research in flavor encapsulation. Covers processes such as extrusion, coacervation, microencapsulation, and molecular inclusion, with special emphasis on spray drying. Discusses various substances, including maltodextrins, corn syrup solids, and alginates, as part of a matrix system for flavor encapsulation. Also discusses wall materials, including acacia gums, carbohydrate-derived polymers, lipophilic starches, protein-based materials, and more. Offers complete and practical coverage of the processes involved. Vital information for flavor researchers as well as those industries for which spray drying offers a promising new technology.

The emergence of the discipline of encapsulation and controlled release has had a great impact on the food and dietary supplements sectors; principally around fortifying food systems with nutrients and health-promoting ingredients. The successful incorporation of these actives in food formulations depends on preserving their stability and bioavailability as well as masking undesirable flavors throughout processing, shelf life and consumption. This second edition of Encapsulation and Controlled Release Technologies in Food Systems serves as an improvement and a complement companion to the first. However, it differentiates itself in two main aspects. Firstly, it introduces the reader to novel encapsulation and controlled release technologies which have not yet been addressed by any existing book on this matter, and secondly, it offers an in-depth discussion on the impact of encapsulation and controlled release technologies on the bioavailability of health ingredients and other actives. In common with the first edition the book includes chapters written by distinguished authors and researchers in their respective areas of specialization. This book is designed as a reference for scientists and formulators in the food, nutraceuticals and consumer products industries who are looking to formulate new or existing products using microencapsulated ingredients. It is also a post-graduate text designed to provide students with an introduction to encapsulation and controlled release along with detailed coverage of various encapsulation technologies and their adaptability to specific applications.

Consumers prefer food products that are tasty, healthy, and convenient. Encapsulation is an important way to meet these demands by delivering food ingredients at the right time and right place. For example, encapsulates may allow flavor retention, mask bad tasting or bad smelling components, stabilize food ingredients, and increase their bioavailability. Encapsulation may also be used to immobilize cells or enzymes in the production of food materials or products, such as fermentation or metabolite production. This book provides a detailed overview of the encapsulation technologies available for use in food products, food processing, and food production. The book aims to inform those who work in academia or R&D about both the delivery of food compounds via encapsulation and food processing using immobilized cells or enzymes. The structure of the book is according to the use of encapsulates for a specific application. Emphasis is placed on strategy, since encapsulation technologies may change. Most chapters include application possibilities of the encapsulation technologies in specific food products or processes. The first part of the book reviews general technologies, food-grade materials, and characterization methods for encapsulates. The second part discusses encapsulates of active ingredients (e.g., aroma, fish oil, minerals, vitamins, peptides, proteins, probiotics) for specific food applications. The last part describes immobilization technologies of cells and enzymes for use within food fermentation processes (e.g., beer, wine, dairy, meat), and food production (e.g., sugar conversion, production of organic acids or amino acids, hydrolysis of triglycerides). Edited by two leading experts in the field, Encapsulation Technologies for Food Active Ingredients and Food Processing will be a valuable reference source for those working in the academia or food industry. The editors work in both industry or academia, and they have brought together in this book contributions from both fields.

Active ingredients in foods must remain fully functional for as long as necessary and be transported and discharged appropriately to have the desired nutritional effect. Delivery and controlled release systems are an essential way to achieve these aims. This important book reviews how to optimise these systems to maximise the health-promoting properties of food products. Opening chapters review factors affecting nutrient bioavailability and methods to test delivery system efficacy. Part two addresses materials used and specific techniques for delivery and release. The benefits and drawbacks of structured lipids, micro- and nano-emulsions, food-protein-derived materials, complexes and conjugates of biopolymers, and starch as an encapsulation material for delivery of functional food ingredients, are all considered. Part three discusses the delivery and controlled release of particular nutraceuticals such as antioxidants and vitamins, folic acid, probiotics, fish oils and proteins. Part four covers regulatory issues and future trends in bioactives and nutraceuticals. Edited by a leading expert in the field, Delivery and controlled release of bioactives in foods and nutraceuticals is a valuable reference for those working in the food industry and particularly those developing nutraceuticals. Reviews techniques to optimise the delivery and release of bioactives in food Discusses the factors that affect nutrient bioavailability and methods to test delivery system efficacy Addresses materials used and specific techniques for delivery and release

Today, nano- and microencapsulation are increasingly beingutilized in the pharmaceutical, textile, agricultural and foodindustries. Microencapsulation is a process in which tiny particlesor droplets of a food are surrounded by a coating to give smallcapsules. These capsules can be imagined as tiny uniform spheres,in which the particles at the core are protected from outsideelements by the protective coating. For example, vitamins can beencapsulated to protect them from the deterioration they wouldundergo if they were exposed to oxygen. This book highlights the principles, applications, toxicity andregulation of nano- and microencapsulated foods. Section I describes the theories and concepts of nano- andmicroencapsulation for foods adapted from pharmaceutical areas,rationales and new strategies of encapsulation, and protection andcontrolled release of food ingredients. Section II looks closely at the nano- and microencapsulation offood ingredients, such as vitamins, minerals, phytochemical, lipid,probiotics and flavors. This section provides a variety ofreferences for functional food ingredients with varioustechnologies of nano particles and microencapsulation. This sectionwill be helpful to food processors and will deal with foodingredients for making newly developed functional foodproducts. Section III covers the application of encapsulated ingredientsto various foods, such as milk and dairy products, beverages,bakery and confectionery products, and related food packagingmaterials. Section IV touches on other related issues in nano- andmicroencapsulation, such as bioavailability, bioactivity, potentialtoxicity and regulation.
