Food process engineering, a branch of both food science and chemical engineering, has evolved over the years since its inception and still is a rapidly changing discipline. While traditionally the main objective of food process engineering was preservation and stabilization, the focus today has shifted to enhance health aspects, flavour and taste, nutrition, sustainable production, food security and also to ensure more diversity for the increasing demand of consumers. The food industry is becoming increasingly competitive and dynamic, and strives to develop high quality, freshly prepared food products. To achieve this objective, food manufacturers are today presented with a growing array of new technologies that have the potential to improve, or replace, conventional processing technologies, to deliver higher quality and better consumer targeted food products, which meet many, if not all, of the demands of the modern consumer. These new, or innovative, technologies are in various stages of development, including some still at the R&D stage, and others that have been commercialised as alternatives to conventional processing technologies. Food process engineering comprises a series of unit operations traditionally applied in the food industry. One major component of these operations relates to the application of heat, directly or indirectly, to provide foods free from pathogenic microorganisms, but also to enhance or intensify other processes, such as extraction, separation or modification of components. The last three decades have also witnessed the advent and adaptation of several operations, processes, and techniques aimed at producing high quality foods, with minimum alteration of sensory and nutritive properties. Some of these innovative technologies have significantly reduced the thermal component in food processing, offering alternative nonthermal methods. Food Processing Technologies: A Comprehensive Review, Three Volume Set covers the latest advances in innovative and nonthermal processing, such as high pressure, pulsed electric fields, radiofrequency, high intensity pulsed light, ultrasound, irradiation and new hurdle technology. Each section will have an introductory article covering the basic principles and applications of each technology, and in-depth articles covering the currently available equipment (and/or the current state of development), food quality and safety, application to various sectors, food laws and regulations, consumer acceptance, advancements and future scope. It will also contain case studies and examples to illustrate state-of-the-art applications. Each section will serve as an excellent reference to food industry professionals involved in the processing of a wide range of food categories, e.g., meat, seafood, beverage, dairy, eggs, fruits and vegetable products, spices, herbs among others.

High pressure processing technology has been adopted worldwide at the industrial level to preserve a wide variety of food products without using heat or chemical preservatives. High Pressure Processing: Technology Principles and Applications will review the basic technology principles and process parameters that govern microbial safety and product quality, an essential requirement for industrial application. This book will be of interest to scientists in the food industry, in particular to those involved in the processing of products such as meat, fish, fruits, and vegetables. The book will be equally important to food microbiologists and processing specialists in both the government and food industry. Moreover, it will be a valuable reference for authorities involved in the import and export of high pressure treated food products. Finally, this update on the science and technology of high pressure processing will be helpful to all academic, industrial, local, and state educators in their educational efforts, as well as a great resource for graduate students interested in learning about state-of-the-art technology in food engineering.

The growing concern for human wellbeing has generated an increase in the demand for polyphenols, secondary plant metabolites that exhibit different bioactive properties. This increasing demand is mainly due to the current applications in the food industry where polyphenols are considered essential for human health and nutrition. Advances in Technologies for Producing Food-relevant Polyphenols provides researchers, scientists, engineers, and professionals involved in the food industry with the latest methodologies and equipment useful to extract, isolate, purify, and analyze polyphenols from different available sources, such as herbs, flora, vegetables, fruits, and agro-industrial wastes. Technologies currently used to add polyphenols to diverse food matrices are also included. This book serves a reference to design and scale-up processes to obtain polyphenols from different plant sources and to produce polyphenol-rich foods with bioactive properties (e.g. antioxidant, antibacterial, antiviral, anticancer properties) of interest for human health and wellbeing.

Industrial high pressure processes open the door to many reactions that are not possible under 'normal' conditions. These are to be found in such different areas as polymerization, catalytic reactions, separations, oil and gas recovery, food processing, biocatalysis and more. The most famous high pressure process is the so-called Haber-Bosch process used for fertilizers and which was awarded a Nobel prize. Following an introduction on historical development, the current state, and future trends, this timely and comprehensive publication goes on to describe different industrial processes, including methanol and other catalytic syntheses, polymerization and renewable energy processes, before covering safety and equipment issues. With its excellent choice of industrial contributions, this handbook offers high quality information not found elsewhere, making it invaluable reading for a broad and interdisciplinary audience.

The aim of this book is to present the fundamentals of high pressure technologies from the perspective of mass transfer phenomena and thermodynamic considerations. Novel food applications are exposed and their relation to chemical analysis, extraction, reaction and particle formation processes are outlined. The chapters are written by a diverse group of scientists with expertise in chemistry, food processes, analytical chemistry, chemical engineering and chemical engineering thermodynamics, and biotechnology. The mission of green food engineering is to promote innovative technologies that reduce or eliminate the use or generation of hazardous materials (solvents, reagents) in the design and operation of food related processes, with the view to improve food safety and quality. Several efficient, environmentally friendly and benign technologies based on the use of high pressure and green solvents have demonstrated to be sustainable alternatives to traditional processes in the food industry. Although hundreds of new ideas are being published in the open literature, reliable engineering tools to simulate and design those processes are still under development. High Pressure Fluid Technology for Green Food Processing presents in-depth analyses and outlines the ways towards their maturity.
