Consumer expectations are systematically growing, with demands for foods with a number of attributes, which are sometimes difficult for manufacturers to meet. The engineering processes that are needed to obtain top-quality foods are a major challenge due to the diversity of raw materials, intermediates, and final products. As in any other enterprise, the food industry must optimize each of the steps in the production chain to attain the best possible results. There is no question that a very important aspect to take into consideration when developing a process, designing a food factory, or modifying existing facilities is the in-depth knowledge of the basic engineering aspects involved in a given project.Introduction to Food Process Engineering covers the fundamental principles necessary to study, understand, and analyze most unit operations in the food engineering domain. It was conceived with two clear objectives in mind: 1) to present all of the subjects in a systematic, coherent, and sequential fashion in order to provide an excellent knowledge base for a number of conventional and unconventional processes encountered in food industry processing lines, as well as novel processes at the research and development stages; 2) to be the best grounding possible for another CRC Press publication, Unit Operations in Food Engineering, Second Edition, by the same authors. These two books can be consulted independently, but at the same time, there is a significant and welcomed match between the two in terms of terminology, definitions, units, symbols, and nomenclature.Highlights of the book include: Dimensional analysis and similaritiesPhysicochemistry of food systemsHeat and mass transfer in foodFood rheologyPhysical properties Water activityThermal processingChilling and freezing EvaporationDehydrationExtensive examples, problems, and solutions

While cereals remain the world’s largest food yield – with more than 2.3 billion metric tons produced annually – consumer demands are on the rise for healthier cereal products with greater nutrition. Cereal Grains: Properties, Processing, and Nutritional Attributes provides a complete exploration of the scientific principles related to domestication, morphology, production, and storage of cereal grains. It also describes their physical and chemical characteristics and explains how these properties relate to industrial processing and nutritional value.This single-authored textbook lays the foundation for subsequent chapters by first addressing the importance of cereals for mankind, the comparative chemical and physical grain properties of the various types of cereal grains, the morphology and grain anatomy of caryopses, and the physiology of fertilization, grain development, and germination. The book then covers grain storage, pest control, industrial dry milling, wet milling, and both dry and fresh masa industries. A discussion of processing, quality control, and the role of cereals in human and animal nutrition rounds out the book’s complete coverage. Each chapter includes a set of up-to-date references along with selected questions to bolster comprehension of the discussed concepts. The book also contains a glossary of 600 scientific and technical terms to aid in the understanding of words used throughout the text. Cereal Grains: Properties, Processing, and Nutritional Attributes was designed especially for students and lecturers, but it is also helpful as a guide for scientists, food product developers, and nutritionists working to stay ahead of the curve.

The search for better strategies to preserve foods with minimal changes during processing has been of great interest in recent decades. Traditionally, edible films and coatings have been used as a partial barrier to moisture, oxygen, and carbon dioxide through selective permeability to gases, as well as improving mechanical handling properties. The advances in this area have been breathtaking, and in fact their implementation in the industry is already a reality. Even so, there are still new developments in various fields and from various perspectives worth reporting.Edible Films and Coatings: Fundamentals and Applications discusses the newest generation of edible films and coatings that are being especially designed to allow the incorporation and/or controlled release of specific additives by means of nanoencapsulation, layer-by-layer assembly, and other promising technologies. Covering the latest novelties in research conducted in the field of edible packaging, it considers state-of-the-art innovations in coatings and films; novel applications, particularly in the design of gourmet foods; new advances in the incorporation of bioactive compounds; and potential applications in agronomy, an as yet little explored area, which could provide considerable advances in the preservation and quality of foods in the field.

In order to successfully produce food products with maximum quality, each stage of processing must be well-designed. Unit Operations in Food Engineering systematically presents the basic information necessary to design food processes and the equipment needed to carry them out. It covers the most common food engineering unit operations in detail, including guidance for carrying out specific design calculations. Initial chapters present transport phenomena basics for momentum, mass, and energy transfer in different unit operations. Later chapters present detailed unit operation descriptions based on fluid transport and heat and mass transfer. Every chapter concludes with a series of solved problems as examples of applied theory.
