Operations in Food Refrigeration


Book Description

The final quality of a food product is impacted heavily by preservation technologies, such as chilling, freezing, and freeze-drying, as well as the numerous pretreatments that are routinely applied to foods. Adequate design and implementation of each of these treatments are critical to ensuring the integrity of the final food product, the productivity of the equipment, and reduced operation costs. Operations in Food Refrigeration explores the fundamental issues involved in heat and mass transfer in food refrigeration and examines aspects of other operations applied to chilled or frozen foods. Following an overview of basic concepts and general calculation procedures involved in cooling, freezing, thawing, and freeze-drying, the book discusses: Sizing, peeling, cutting, sorting, and blanching fruits and vegetables Pretreatments for meats, including tenderization, electrical stimulation, portioning, curing, and smoking Pretreatments for fish and other seafood Processing of poultry Air and osmotic partial dehydration, infusion of special nutrients, and the concentration of juices Traditional chilling and freezing methods Special precooling and freezing techniques The effects of thawing on food, factors that influence the choice and design of thawing processes, and various thawing methods Freeze-drying equipment Each chapter is written by a recognized specialist and can serve as a stand-alone resource for the particular topic. Several chapters present case studies that can be used for developing processes or in teaching applications. Processors, researchers, and educators in the food industry will find this volume to be an invaluable reference for a host of food operations.

Unit Operations in Food Processing


Book Description

This long awaited second edition of a popular textbook has a simple and direct approach to the diversity and complexity of food processing. It explains the principles of operations and illustrates them by individual processes. The new edition has been enlarged to include sections on freezing, drying, psychrometry, and a completely new section on mechanical refrigeration. All the units have been converted to SI measure. Each chapter contains unworked examples to help the student gain a grasp of the subject, and although primarily intended for the student food technologist or process engineer, this book will also be useful to technical workers in the food industry




Modeling Food Processing Operations


Book Description

Computational modeling is an important tool for understanding and improving food processing and manufacturing. It is used for many different purposes, including process design and process optimization. However, modeling goes beyond the process and can include applications to understand and optimize food storage and the food supply chain, and to perform a life cycle analysis. Modeling Food Processing Operations provides a comprehensive overview of the various applications of modeling in conventional food processing. The needs of industry, current practices, and state-of-the-art technologies are examined, and case studies are provided. Part One provides an introduction to the topic, with a particular focus on modeling and simulation strategies in food processing operations. Part Two reviews the modeling of various food processes involving heating and cooling. These processes include: thermal inactivation; sterilization and pasteurization; drying; baking; frying; and chilled and frozen food processing, storage and display. Part Three examines the modeling of multiphase unit operations such as membrane separation, extrusion processes and food digestion, and reviews models used to optimize food distribution. - Comprehensively reviews the various applications of modeling in conventional food processing - Examines the modeling of multiphase unit operations and various food processes involving heating and cooling - Analyzes the models used to optimize food distribution




Food Processing Operations and Scale-up


Book Description

Intended for students and practitioners who have a basic education in chemical engineering or food science. Contains basic information in each area and describes some of the fundamental ideas of processing development and design. Examines the food industry structure, how it works, consumer products,




Quantitative Microbiology in Food Processing


Book Description

Microorganisms are essential for the production of many foods, including cheese, yoghurt, and bread, but they can also cause spoilage and diseases. Quantitative Microbiology of Food Processing: Modeling the Microbial Ecology explores the effects of food processing techniques on these microorganisms, the microbial ecology of food, and the surrounding issues concerning contemporary food safety and stability. Whilst literature has been written on these separate topics, this book seamlessly integrates all these concepts in a unique and comprehensive guide. Each chapter includes background information regarding a specific unit operation, discussion of quantitative aspects, and examples of food processes in which the unit operation plays a major role in microbial safety. This is the perfect text for those seeking to understand the quantitative effects of unit operations and beyond on the fate of foodborne microorganisms in different foods. Quantitative Microbiology of Food Processing is an invaluable resource for students, scientists, and professionals of both food engineering and food microbiology.




Food Process Engineering


Book Description

Food Process Engineering: Safety Assurance and Complements pursues a logical sequence of coverage of industrial processing of food and raw material where safety and complementary issues are germane. Measures to guarantee food safety are addressed at start, and the most relevant intrinsic and extrinsic factors are reviewed, followed by description of unit operations that control microbial activity via the supply of heat supply or the removal of heat. Operations prior and posterior are presented, as is the case of handling, cleaning, disinfection and rinsing, and effluent treatment and packaging, complemented by a brief introduction to industrial utilities normally present in a food plant. Key Features: Overviews the technological issues encompassing properties of food products Provides comprehensive mathematical simulation of food processes Analyzes the engineering of foods at large, and safety and complementary operations in particular, with systematic derivation of all relevant formulae Discusses equipment features required by the underlying processes

Food Process Engineering


Book Description

The Second Edition of Food Process Engineering by Dr. Dennis Heldman, my former student, and co-author Paul Singh, his former student, attests to the importance of the previous edition. In the Foreword to the First Edition, I noted the need for people in all facets of the food processing industry to consider those variables of design of particular importance in engineering for the food processing field. In addition to recognizing the many variables involved in the biological food product being handled from production to consumption, the engi neer must oftentimes adapt equations developed for non-biological materials. As more and more research is done, those equations are appropriately modified to be more accurate or new equations are developed specifically for designing to process foods. This Edition updates equations used. This book serves a very important need in acquainting engineers and technologists, particularly those with a math ematics and physics background, with the information necessary to provide a more efficient design to accomplish the objectives. Of prime importance, at present and in the future, is to design for efficient use of energy. Now, it is often economical to put considerably more money into first costs for an efficient design than previously, when energy costs were a much smaller proportion of the total cost of process engineering.
