This text provides a comprehensive and thorough overview of kinetic modelling in food systems, which will allow researchers to further their knowledge on the chemistry and practical use of modelling techniques. The main emphasis is on performing kinetic analyses and creating models, employing a hands-on approach focused on putting the content discussed to direct use. The book lays out the requisite basic information and data surrounding kinetic modelling, presents examples of applications to different problems and provides exercises that can be solved utilizing the data provided. Kinetic Analysis of Food Systems pursues a practical approach to kinetic analysis, providing helpful exercises involving chlorophyll degradation in processed vegetables, metabolic oscillations and sugar accumulation in cold-stored potatoes, transesterification of oils to manufacture biodiesel, aggregation of whey proteins to make protein gels and crystallization of fat stabilizers used in nut butters, among others. The book lays out the basics of kinetic modelling and develops several new models for the study of these complex systems. Taken together with the accompanying exercises, they offer a full portrait of kinetic analysis, from its basic scientific groundwork to its application.
Calorimetry in Food Processing: Analysis and Design of Food Systems introduces the basic principles of calorimetry and highlights various applications of calorimetry to characterize temperature-induced changes including starch gelatinization and crystallization, lipid transitions, protein denaturation, and inactivation of microorganisms in a variety of food and biological materials. Emphasis is given to the use of calorimetry as a tool for evaluation of processing requirements in order to assess the efficacy of food processing and for characterization of the effects of changes in formulation and processing conditions.
The level of quality that food maintains as it travels down the production-to-consumption path is largely determined by the chemical, biochemical, physical, and microbiological changes that take place during its processing and storage. Authored by an internationally respected food quality expert, Kinetic Modeling of Reactions in Foods demonstrates
As the complexity of the food supply system increases, the focus on processes used to convert raw food materials and ingredients into consumer food products becomes more important. The Handbook of Food Engineering, Third Edition, continues to provide students and food engineering professionals with the latest information needed to improve the efficiency of the food supply system. As with the previous editions, this book contains the latest information on the thermophysical properties of foods and kinetic constants needed to estimate changes in key components of foods during manufacturing and distribution. Illustrations are used to demonstrate the applications of the information to process design. Researchers should be able to use the information to pursue new directions in process development and design, and to identify future directions for research on the physical properties of foods and kinetics of changes in the food throughout the supply system. Features Covers basic concepts of transport and storage of liquids and solids, heating and cooling of foods, and food ingredients New chapter covers nanoscale science in food systems Includes chapters on mass transfer in foods and membrane processes for liquid concentration and other applications Discusses specific unit operations on freezing, concentration, dehydration, thermal processing, and extrusion The first four chapters of the Third Edition focus primarily on the properties of foods and food ingredients with a new chapter on nanoscale applications in foods. Each of the eleven chapters that follow has a focus on one of the more traditional unit operations used throughout the food supply system. Major revisions and/or updates have been incorporated into chapters on heating and cooling processes, membrane processes, extrusion processes, and cleaning operations.
It has been nearly a decade since the third edition of Engineering Properties of Foods was published, and food structure/microstructure remains a subject of research interest. In fact, significant developments have taken place in the area of high pressure processing (HPP), which has been approved for pasteurization of food by the Food and Drug Administration.
Much of man's behaviour is controlled by appearance, but the appearance of his food is of paramount importance to his health and well-being. In day-to-day survival and marketing situations, we can tell whether or not most foods are fit to eat from their optical properties. Although vision and colour perception are the means by which we appreciate our surroundings, visual acceptance depends on more than just colour. It depends on total appearance. In the recent past the food technologist has been under pressure to increase his/her understanding of first, the behaviour of raw materials under processing, and second, the behaviour and motivation of his/her customers in a growing, more discriminating, and worldwide market. The chapters which follow describe the philosophy of total ap pearance, the factors comprising it, and its application to the food industry. Included are: considerations of the evolutionary, historical, and cultural aspects of food appearance; the physics and food chemistry of colour and appearance; the principles of sensory ap pearance assessment and appearance profile analysis, as well as instrumental measurement; the interaction of product appearance, control, and acceptance in the varied environments of the laboratory, production line, supermarket, home and restaurant. A broad examination has been made in an attempt to get into perspective the importance of appearance to all sectors of the industry.
The quality and safety of the food we eat deserves the utmost attention and is a priority for producers and consumers alike. Shelf life studies provide important information to manufacturers and consumers to ensure a high-quality food product. Various evaluation methods are used for shelf life determination and they are usually performed at the manufacturer level. Moreover, various techniques are utilized throughout the food chain that enhance the shelf life of food products. This sensitive issue is reviewed in Shelf Life and Food Safety, which brings together a group of subject experts to present up-to-date and objective discussions on a broad range of topics including food spoilage and safe preservation, packaging, and sensory aspects. The book presents both traditional and innovative technologies for enhancing food safety and increasing shelf life, along with methods for the assessment and prediction of food safety and shelf life. Key Features Overviews the issues associated with shelf life enhancement and shelf life evaluation of various food products Addresses issues important to maintaining food safety Explains how shelf life depends on factors, including ingredients for formulation, processing techniques, packaging, and storage conditions Covers shelf life evaluation methods, determinants for shelf life, food quality assessment, and basic and innovative technologies that will improve the shelf life of food products This book is the first of its kind focusing on issues related to evaluation techniques for shelf life determinants, and techniques for shelf life enhancement. It is appropriate for students, researchers, scientists, and professionals in food science and technology. It is also a helpful source of information for people involved in the food industry, food processing sector, product development, marketing, and other associated fields.
Advances in Food Authenticity Testing covers a topic that is of great importance to both the food industry whose responsibility it is to provide clear and accurate labeling of their products and maintain food safety and the government agencies and organizations that are tasked with the verification of claims of food authenticity.
