During this time, thousands of patents and academic papers have been written and published along with over 50 books on this topic. Yet, with all this effort, there is a tremendous inter- est inthis field. Every year conferences andshort coursesare offered that are well attended.Every year at mycompany we field over 300 calls from companies that are excited and intrigued about how microencapsulation can provide their product or idea intellectual and physical protection in their markets. The use of microencapsulation methodologies for markets as diverse as the food, pharmaceutical, industrial, personal and home care, and agribusiness sectors, has made this area diverse, broad, and challenging to understand. Furthermore, the many techniques that are used in this field tend to have very specific limitations, advantages, and trade secret modifications that compound the challenges to both newandexperiencedpractitioners. Ten years ago, Dr. Anilkumar Gaonkar, with the help of many contributors to this book, organized the Pre-IFT meeting short course on microencapsulation especially targeted for the food industry professionals. This short course continued as a yearly offering from the IFT. Five years ago some of the contributors to this book and I realized that a newshortcourseonmicroencapsulationcouldbeusefultothegeneralpublic.Dr.MarcMeyersspearheadedtheorgani- zation of that course and it included many of the authors that are in this book. What was unique about these courses was the focus on a wide range of microencapsulation methods combined with applied examples and some of the practi- cal issues that are easy to overlook considering the breadth and variety of the process solutions. This book addresses these tremendously important issues such as the economics of microencapsulation, scale-up issues, and a whole section on the materials that are used in microencapsulation. Through overviews, process descriptions, materials that can be used to provide the encapsulation, production and regulatory issues, and finally interesting application examples, the editors and contributors of this book have provided a clear and complete reference to this complicated area for both the microencapsulationproducersandtheusersofmicroencapsulation. For over half a century, microencapsulation has been an exciting and industrially significant area to work in. New materials, better process controls, and a continuing need to protect and deliver active ingredients on demand will push this field tonew heights. This bookwill provideyou, the reader, with a reference tothe technology and challenges and, hopefully,expandyourthinkingand,ultimately,thebreadthofthetechnology. Goodreading,gooddreaming,andgoodinnovation. WillieHendrickson,Ph.D. CEO AVEKAGroup xiii Preface The world of Microencapsulation has seen exponential growth over the past fifty years, and particularly more so over the last decade. We, the authors, have held hands over the years, providing our scientific insight to evolving product development demands as attendees at international conferences and workshops. It was June 2011 when one of us, Anilkumar, had an epiphany (cid:1) it would be quite helpful for the attending audience if we captured our collective learn- ing,experiences,andpractices,alongwithourmicroencapsulationcolleaguesaroundtheworld,andcreatedahandbook of practical wisdom all in one place. The rest was history, and this was the genesis of our adventure together. A team of qualified experts was sought with a core team to create, compile, edit, and format each selection. We thank Elsevier forseeingourvisionandappreciatetheirpatienceingettingthebookreadyforprint. We recognized that the fundamental researchers and scientists were seeking technology nuances. Finding these nug- gets in this much-evolved field of science is difficult. Honestly, one would be misleading the reader if we state that what is presented in the chapters is simply science. Microencapsulation is an art and a science, and we hope that the bookhasdonejusticeinbalancingthetwoacts. Afew earlier pieces ofliterature inthe field ofmicroencapsulation have tappedinbasicconcepts, and fundamentals ofunderstandingoftheprocesstechnologies.Weunderstandthattoday’sreaderiswellversedinsuchfundamentalcon- cepts and basics. We felt that a focus on industrial applications pertinent to the 21st century would yield greater value to the reader. This involves exploring novel excipients, process technologies, analytical and characterization methods, and regulatory roadmaps. We believe thatthis extends our understanding ofthe functionality ofthe finalmicroencapsu- latedproduct. The thirst of today’s learners relates to finding unique solutions to some very specific product needs. As research and development is not a static practice, the field of encapsulation has traversed from the micro-scale level to new developments in the area of nano-scaled encapsulation. These developments have found many applications in health foods,nutraceuticals,dietaryandconsumerhealth,andwellnessproducts. Thisbookiscomprisedof7partsand42chapters.Wehaveattemptedtobridgefundamentalconceptstotheknowl- edge of new and novel processing techniques, choice of materials along with the selection process, testing and evalua- tion of materials, regulatory aspects, scale-up, packaging, economics, and application-specific uses of microencapsulation in the food industry. We have chosen to include the expired and active intellectual property highlighting this field of research as it applies to the food and nutraceutical industries. The content and format allows ustocreateanIndustrialApplicationHandbookcapturingtheartandscienceofthisfieldtothefoodindustry. The book provides a single source consolidation of information pertaining to new challenges in the food industry that can potentially be solved by microencapsulation technology. The projected audience encompasses college students, scientists, engineers, professionals, business managers, technical leaders, marketing personnel, and small business own- ers serving the food and nutraceutical industries. Most of the contributors to this book are from industry and a few are fromacademia.Hundredsofyearsofcollectiveexperience ofthe authors fromseveralcountrieshave shapedthisbook. We hope that the readers of this book will be enriched with knowledge of the current and emerging trends on microen- capsulationoffoodingredients. TheEditors xv About the Editors Anilkumar G.
