Food Freezing and Thawing Calculations


Book Description

Freezing time and freezing heat load are the two most important factors determining the economics of food freezers. This Brief will review and describe the principal methods available for their calculation. The methods can be classified into analytical methods, which rely on making physical simplifications to be able to derive exact solutions; empirical methods, which use regression techniques to derive simplified equations from experimental data or numerical calculations and numerical methods, which use computational techniques such as finite elements analysis to solve the complete set of equations describing the physical process. The Brief will evaluate the methods against experimental data and develop guidelines on the choice of method. Whatever technique is used, the accuracy of the results depends crucially on the input parameters such as the heat transfer coefficient and the product's thermal properties. In addition, the estimation methods and data for these parameters will be reviewed and their impacts on the calculations will be evaluated. Freezing is often accompanied by mass transfer (moisture loss, solute absorption), super cooling and nucleation and may take place under high pressure conditions; therefore methods to take these phenomena into account will also be reviewed.

Frozen Food Science and Technology


Book Description

This book provides a comprehensive source of information on freezing and frozen storage of food. Initial chapters describe the freezing process and provide a fundamental understanding of the thermal and physical processes that occur during freezing. Experts in each stage of the frozen cold chain provide, within dedicated chapters, guidelines and advice on how to freeze food and maintain its quality during storage, transport, retail display and in the home. Individual chapters deal with specific aspects of freezing relevant to the main food commodities: meat, fish, fruit and vegetables. Legislation and new freezing processes are also covered. Frozen Food Science and Technology offers in-depth knowledge of current and emerging refrigeration technologies along the entire frozen food chain, enabling readers to optimise the quality of frozen food products. It is aimed at food scientists, technologists and engineers within the frozen food industry; frozen food retailers; and researchers and students of food science and technology.

Food Coatings and Preservation Technologies


Book Description

This book compiles recent studies about edible coatings and how they have improved food products, packaging techniques, and product quality to cause fewer health risks. Food Coatings and Preservation Technologies presents the most recent studies about the application of edible coatings to a wide variety of foods. Edible coatings are globally utilized for preventing food product contamination from harmful microorganisms and pathogens. This book highlights the developments made in designing new edible coatings. Herein, particular attention is given to the main components, manufacturing methods, and their application to specific products. The book also discusses the current state-of-the-art alternative to conventional package usage, providing the main features biodegradable packaging should meet for distinct uses for the conservation and improvement of various food products. This information will be helpful for processors to select the best coating material and its effective concentration for different fresh and minimal processed vegetables. Each chapter delves into edible-based coating research and critical developments to enhance food preservation standards. The first section focuses on biopolymer-based edible coatings, food packaging, and preservation. It provides a comprehensive understanding of the current state and critical developments in biodegradable polymer packaging systems for food applications. As technology advances, the next section highlights ongoing research focusing on optimizing coating effectiveness and the development of eco-friendly and sustainable materials. This section’s objective is to identify edible materials and combine the most recent information available to provide a comprehensive understanding of formulation methods and approaches to enhancing the properties of the coatings applied to food products. The final section discusses encapsulation techniques and levels of retention to improve shelf-life. Readers will find in this book information concerning: The efficiency and functional properties of edible coating materials; Feasibility studies performed on new process evaluation, safety and toxicity determination, regulatory assessment, and consumer studies regarding the commercial uses of edible coatings; Coating technologies that present a promising avenue to enhance the delivery, stability, and efficacy of medical foods and nutraceuticals; Shelf-life testing that suggests future directions; Novel practical and reliable tools that are applicable in the industrial process. Audience The book is aimed at chemists, food technologists, food scientists, nutritionists, dietitians, pharmaceutical technologists, biochemists, and engineers, as well as postgraduate, PhD students and postdocs working in the area of edible food coatings and prevention technologies.
