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.

Spray drying is a well-established method for transforming liquid materials into dry powder form. Widely used in the food and pharmaceutical industries, this technology produces high quality powders with low moisture content, resulting in a wide range of shelf stable food and other biologically significant products. Encapsulation technology for bioactive compounds has gained momentum in the last few decades and a series of valuable food compounds, namely flavours, carotenoids and microbial cells have been successfully encapsulated using spray drying. Spray Drying Technique for Food Ingredient Encapsulation provides an insight into the engineering aspects of the spray drying process in relation to the encapsulation of food ingredients, choice of wall materials, and an overview of the various food ingredients encapsulated using spray drying. The book also throws light upon the recent advancements in the field of encapsulation by spray drying, i.e., nanospray dryers for production of nanocapsules and computational fluid dynamics (CFD) modeling. Addressing the basics of the technology and its applications, the book will be a reference for scientists, engineers and product developers in the industry.

An accessible guide to safely dehydrating food Freeze drying, or lyophilization, is a method for dehydrating food or other substances through the use of pressure instead of heat. This allows for the preservation and storage of high-value food products without altering their essential properties or causing a reduction in quality or value. For these reasons, freeze drying is the most reliable method for preserving and distributing high-quality products. Freeze Drying of Food Products provides a concise, accessible overview of freeze-drying techniques and their modern applications. Beginning with the basic principles and processes of freeze drying, it incorporates specific discussion of freeze-drying different categories of food products, before moving to an analysis of recent developments in freeze-drying technology. The result is a key publication in the fight to extend the shelf-life of food products and expand the distribution of high-quality freeze-dried foods. Freeze Drying of Food Products readers will also find: An editorial team with a wide range of pertinent research experience Detailed discussion of different freeze-drying processes such as vacuum drying, atmospheric drying, and spray drying Commercial Applications of freeze-dried food products Freeze Drying of Food Products is ideal for researchers and industry professionals involved in food production, food distribution, or food biotechnology, as well as students studying these and other related fields.

Nanoencapsulation has the potential to improve human health through its capacity to both protect bioactive compounds and release them at a specific time and location into various substances, including food. Numerous nanoencapsulation technologies have emerged in recent years, each with its own advantages and disadvantages. The goal of this Brief is to discuss the various nanoencapsulation technologies, such as emulsification, coacervation, inclusion encapsulation, anti-solvent precipitation, nanoprecipitation, freeze drying, and spray drying, including their limitations. Recent safety and regulatory issues concerning the various nanoencapsulation technologies will also be covered.

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.
