A number of food engineering operations, in which heat is not used as a preserving factor, have been employed and are applied for preparation (cleaning, sorting, etc.), conversion (milling, agglomeration, etc.) or preservation (irradiation, high pressure processing, pulsed electric fields, etc.) purposes in the food industry. This book presents a comprehensive treatise of all normally used food engineering operations that are carried out at room (or ambient) conditions, whether they are aimed at producing microbiologically safe foods with minimum alteration to sensory and nutritive properties, or they constitute routine preparative or transformation operations. The book is written for both undergraduate and graduate students, as well as for educators and practicing food process engineers. It reviews theoretical concepts, analyzes their use in operating variables of equipment, and discusses in detail different applications in diverse food processes.

This useful reference is the first book to address key aspects of food powder technology. It assembles organized and updated information on the physical properties, production, and functionality of food powder, previously unavailable in book form.

Suitable for practicing engineers and engineers in training, Unit Operations of Particulate Solids: Theory and Practice presents the unit operations in chemical engineering that involve the handling and processing of particulate solids.

The first part of the book analyzes primary and secondary properties of particles and particulate systems, focusing on their characterization and the effects on selection and design of silos and conveyors. Covering the main industrial operations of dry solids processing, the second part offers insight into the operation principles of the most important technologies that handle dry solids in bulk. With an emphasis on two-phase and multiphase flow, the final part describes all of the relevant systems in industrial processes that combine two different components of the state of matter as well as technologies for separating phases by purely mechanical means.

Through clear explanations of theoretical principles and practical laboratory exercises, this book provides an understanding of the behavior of powders and pulverized systems. It also helps readers develop skills for operating, optimizing, and innovating particle processing technologies and machinery in order to carry out industrial operations, such as centrifugation, filtration, and membrane separations.

Covers a Host of Groundbreaking Techniques Thermal processing is known to effectively control microbial populations in food, but the procedure also has a downside it can break down the biochemical composition of foods, resulting in a marked loss of sensory and nutritional quality. Processing Effects on Safety and Quality of Foods delineates three decades of advances made in processing techniques that produce microbiologically safe foods, while maintaining their sensory and nutritive properties. Addresses the Entire Food Processing Industry With an international team of more than 35 renowned contributors, this book presents evaluation techniques that yield reliable estimations of microbiological, physicochemical, nutritive, and sensory characteristics. Each chapter discusses the processing effects of relevant technologies and includes the basics of microbial kinetics, sensory evaluation, and the perception of food quality. A sampling of the techniques covered: Hermetically sealed containers Acrylamide formation Dried foods Irradiated foods Pressure-assisted thermal processing Pulsed electric field processing Processing Effects on Safety and Quality of Foods addresses the entire food processing industry, including food modeling, optimization, and proper design of manufacturing plants. It is the first of its kind a single, sound reference that explores all of the different aspects involved in evaluating processing effects in food safety and quality.

En diversas industrias de procesamiento de materiales, tales como la quimica, farmaceutica o alimentaria, se manejan sistemas bifasicos o multifasicos que requieren separar sus componentes. Ya sea que se trate de una mezcla de solidos o de una suspension solido-fluido, las operaciones industriales para recuperar en la forma mas pura un precipitado o un clarificado son numerosas. El presente texto constituye un tratado sobre las tecnicas de separacion industriales, en las que se utilizan fuerzas mecanicas para segregar una o mas fases de suspensiones, licores de proceso, lodos de efluentes, etc. Las operaciones que aborda el texto son aquellas que se llevan a cabo utilizando equipos tales como tamices, tanques de sedimentacion, centrifugas o filtros. Se estudian las propiedades de los componentes de los fluidos multifasicos, tales como comportamiento de particulas en el seno de un fluido o reologia se suspensiones de diversas concentraciones, para pasar a abordar las operaciones de separacion de mezclas solidas, sistemas solido-gas y sistemas solido-liquido. El texto puede ser util para estudiantes o docentes de educacion superior y para ingenieros de proceso."
