Download or read book Effect of High Pressure Technologies on Enzymes Applied in Food Processing written by Bruno Ricardo de and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Recent Developments in High Pressure Processing of Foods written by Navin K Rastogi and published by Springer Science & Business Media. This book was released on 2013-07-16 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Natural Additives in Foods written by German Ayala Valencia and published by Springer Nature. This book was released on 2022-12-16 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additives have been used in the food sector for centuries, aiming to maintain or improve food quality in terms of freshness, appearance, texture and taste. Most food additives are synthetic chemical compounds classified as antioxidants, antimicrobials, colorants and sweeteners. In the last decades, several synthetic food additives have been correlated with adverse reactions in humans, which has caused the safety of synthetic food additives to be reviewed and discussed by international organizations. At the same time, there is increasing consumer demand for more natural and environmentally friendly food products and additives. Therefore, synthetic food additives have been replaced with natural food additives. Although the use of natural additives is a hot topic in food science, to date no book has systematically reviewed the application of natural additives in food products. ​ Natural additives in foods presents an exhaustive analysis of the most recent advances in the application of natural additives in the food sector. Covering natural antioxidants, antimicrobials, colorants and sweeteners, this text also focuses on unconventional sources of natural additives, valorization and toxicological aspects, consumer attitudes and regulatory aspects. The main applications of natural antioxidants are fully covered, including polyphenols, ascorbic acid, carotenoids, tocopherols and proteins. Natural antimicrobial applications from polyphenols and essential oils to poly-L-Lysine are analyzed, as are natural colorants like anthocyanins, annatto, betalains and paprika. The encapsulation, trapping, and adsorption of natural additives are studied, and consumer perceptions and preferences are major focuses. Researchers will find up-to-date regulatory specifics for the United States and European Union. For any researcher in need of an expansive single source containing all relevant and updated information for the use of natural additives in foods, this book is a much needed addition to the field.

Download or read book Ultra High Pressure Treatment of Foods written by Marc E.G. Hendrickx and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, consumer demand for convenient, fresh-like, safe, high-quality food products has grown. The food industry has responded by applying a number of new technologies including high hydrostatic pressure for food processing and preservation. In addition, food scientists have demonstrated the feasibility of industrial-scale high pressure processing. This technology is of specific interest to the food industry because it provides an attractive alternative to conventional methods of thermal processing, which often produce undesirable changes in foods and hamper the balance between high quality (color, flavor, and functionality) and safety. In addition, it offers opportunities for creating new ingredients and products because of the specific actions of high pressure on bio logical materials and food constituents. It allows food scientists to redesign exist ing processes and to create entirely new ones using high pressure technology alone or in combination with conventional processes (e. g. , pressure-temperature combinations ). Researchers have investigated high pressure processing for the past century. Scientists such as Hite and Bridgman did pioneering work at the turn of the 20th century. Then during the 1980s and 1990s, there was a large effort to investigate the effects of high pressure on biological materials, particularly foods. The initial research activities in the late 1980s and early 1990s focused on exploratory activ ities in the food area.
