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.

Book Description
Sustainable Fish Production and Processing is a unique resource that bridges the gap between academia and industry by analyzing new, state-of-the-art fish production, processing and waste management. The book explores general valorization methods, focusing on the extraction of high added-value compounds and their reutilization in different fields of the food and nutraceuticals industry. Sections take a comprehensive approach to understanding the most recent advances in the field, while also analyzing the potentiality and sustainability of already commercialized processes and products. This resource could be utilized as a handbook for anyone dealing with sustainability issues within the fish industry.Emphasis of fish production is given to food security issues, large marine ecosystems, aquaculture genomics, epigenetics and breeding, proteomics for quality and safety in fishery products, post-harvest practices in small scale fisheries, and lifecycle impact of industrial aquaculture systems. Emphasis of fish processing and by-products is given to industrial thawing of fish blocks, sources and functional properties of fish protein hydrolysates, recovery technologies and applications, potential biomedical applications, ready-to-eat products, fish waste for bacterial protease production, fish waste for feeding as well as lipid extraction from fish processing for biofuels. - Covers recent advances in the field of fish production and processing over the last decade, following sustainability principles - Discusses the advantages and disadvantages of relevant processes from various perspectives to improve sustainability - Offers practical success stories and solutions to ensure the sustainable management of fish processing by-products

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.
