Effect of High-Pressure Technologies on Enzyme: Science and Applications provides a deep, practical discussion of high-pressure processing (HPP) and high-pressure homogenization (HPH) technologies and biochemical approaches, applied across research and industry, with applications ranging from food to pharmaceuticals and commercial enzyme production. Early chapters discuss foundational aspects of HPP and HPH approaches; the science of enzyme modification; and basic aspects of enzyme activity, stability, and structure as studied in biochemical processes. Later chapters consider the effect of HPP and HPH technologies and their mechanisms of controlling enzyme modification to improve enzyme performance for chosen applications. Special attention is paid to the application of HPP and HPH technologies and enzyme modifications in food processing, microbial enzyme modification, drug discovery, and production of other commercial enzymes, as well as the challenges of undesirable enzyme inactivation. The final chapter discusses future directions of the field and technologies, and expanded applications. Offers a broad overview of HPP and HPH approaches and technologies applied in enzyme modification Introduces fundamental aspects of enzyme activity, stability, and structure as studied in biochemical processes and applications Discusses applications of HPP- and HPH-based enzyme modifications in food processing, microbial enzyme modification, drug discovery, and production of other commercial enzymes Includes chapter contributions from international leaders in the field, across research and industry

High isostatic pressure (HIP) and high-pressure homogenization (HPH) are considered important physical technologies that able to induce changes on enzymes. HIP and HPH are emerging food processing technologies that involve the use of ultra high pressures (up to 1200 MPa for HIP and up to 400 MPa for HPH), where the first process is based on the principle that the maintenance of a product inside vessels at high pressures induces changes in the molecules conformation and, consequently, in the functionality of polysaccharides, proteins and enzymes. To the contrary, for HPH process, the high shear and sudden pressure drop are the responsible phenomena for the changes on the processed product. This chapter aims to evaluate comparatively the effects of HIP and HPH on the activity of enzymes currently applied in food industry and to identify the main structural changes induced by each process. The overall evaluation of the results shows that mild conditions of both processes were recently highlighted as able to improve the activity and the stability of several enzymes, whereas extreme process conditions (pressure, time and temperature) induce enzyme denaturation with consequent reduction of biological activity. Considering the complexity and diversity involved in the enzyme structure and its ability to react, it is not possible to determine specific conditions that each process is able to promote increase or reduction of enzyme activity, being necessary to evaluate HIP and HPH for each enzyme. Finally, in terms of molecular structure, the effect of HIP and HPH on enzymes can be explained by the alterations in the quaternary, tertiary and secondary structures of enzymes, which directly affects its active site configuration.

Features a Foreword by Dr. Dietrich Knorr. Fruit processing and preservation technologies must ensure fresh-like characteristics in foods while providing an acceptable and convenient shelf life, as well as assuring safety and nutritional value. Processing technologies include a wide range of methodologies to inactivate microorganisms, improve quality and stability, and preserve and minimize changes of fresh-like characteristics in fruit. High pressure as a food preservation technique inactivates microorganisms at room temperature or lower; thus, sensory and nutritional characteristics can be maintained. In recent years, a significant increase in the number of scientific papers in literature demonstrating novel and diversified uses of high pressure processing indicates it to be highly emerging technology. The effect of high pressure technology on the quality and safety of foods will be discussed. Selected practical examples in fruits and vegetables, dairy and meat industries using high pressure will be presented and discussed. A brief account of the challenges in adopting this technology for industrial development will also be included.
