A must for all serious students and practitioners involved in winemaking.

Download or read book Anthocyanins written by Kevin Gould and published by Springer Science & Business Media. This book was released on 2008-12-19 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been an unprecedented expansion of knowledge about anthocyanins pigments. Indeed, the molecular genetic control of anthocyanins biosynthesis is now one of the best understood of all secondary metabolic pathways. There have also been substantial improvements in analytical technology that have led to the discovery of novel anthocyanin compounds. Armed with this knowledge and the tools for genetic engineering, plant breeders are now introducing vibrant new colors into horticultural crops. The food industry has also benefited from the resurgence of interest in anthocyanins. A greater understanding of the chemistry of these pigments has led to improved methods for stabilizing the color of anthocyanins extracts, so that they are more useful as food colorings. Methods for the bulk production of anthocyanins from cell cultures have been optimized for this purpose. Possible benefits to human health from the ingestion of anthocyanin-rich foods have also been a major feature of the recent scientific literature. Anthocyanins are remarkably potent antioxidants, and their ingestion has been postulated to stave off the effects of oxidative stress. These pigments, especially in conjunction with other flavonoids, have been associated with reductions in the incidence and severity of many other non-infectious diseases, including diabetes, cardiovascular disease and certain cancers. An industry is developing around anthocyanins as nutritional supplements. Finally, there has been significant progress in our understanding of the benefits of anthocyanins to plants themselves. Originally considered an extravagance without a purpose, anthocyanins are now implicated in multifarious vital functions. These include the attraction of pollinators and frugivores, aposematic defense from herbivores, and protection from environmental stressors such as strong light, UVB, drought, and free radical attacks. Anthocyanins are evidently highly versatile, and enormously useful to plants. This book covers all aspects of the biosynthesis and function of anthocyanins (and related compounds such as proanthocyanidins) in plants, and their applications in agriculture, food products, and human health. Featured areas include their relevance to: * Plant stress * Flower and fruit color * Human health * Wine quality and health attributes * Food colorants and ingredients * Cell culture production systems * The pastoral sector

Download or read book Production Wine Analysis written by Bruce W. Zoecklein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is designed to acquaint the reader with the commonly used procedures of juice and wine analysis as they are generally practiced in the industry, and as they are taught in the Department of Enology at California State University, Fresno. It is assumed that the reader has a basic preparation in the fields of chemistry and microbiology. In developing material for this text, the authors have emphasized analyses as they would be carried out in a production laboratory. Realizing that different laboratories have different analytical capabilities, personnel as well as equip ment, we have in many instances provided several different approaches to the same analysis. Throughout this book we have attempted to give special attention to practical considerations and the importance of these analyses in the total spectrum of winery operations. We hope the book's format will satisfy the inter ests oflaboratory personnel as well as winemakers. The process of making wine involves a series of concerns for the winemaker and staff of a winery. The first concerns are viticultural. Upon arrival of the fruit, its quality is assessed, grapes are processed and fermentation is begun. Almost immediately, and in many instances simultaneously, chemical and microbiological stability of the young and/or aging wine become important. Finally, problems do occur on occasion, and a number of what may be consid ered remedial techniques can be employed to produce an acceptable product.

Download or read book Chemistry and Significance of Condensed Tannins written by Richard W. Hemingway and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was developed from the proceedings of the first North American Tannin Conference held in Port. Angeles, Washington, August 1988. The objective of the conference was to bring together people with a common interest in condensed tannins and to promote interdisciplinary interactions that will lead to a better understanding of these important substances. Anot. her objective was the publicat. ion of this book because there has not been a monograph devoted to the chemistry and significance of tannins for several decades. The book is organized into sections dealing with the biosynthesis, structure, re actions, complexation with other biopolymers, biological significance, and use of tannins as specialty chemicals. The authors made a special attempt to focus on what we don't know as well as to provide a summary of what we do know in an effort to assist in planning future research. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We also thank Rylee Geboski and the Conference Assist. ance Staff, College of Forestry, Oregon State University, for their assistance in planning and conducting t. he conference, and Julia Wilson, Debbie Wolfe, Helen Coletka, and Nancy Greene of the Southern Forest Experiment Station, Pineville, Louisiana, who typed the chapt. ers. Linda Chalker-Scott was especially helpful in assisting us wit. h editing. Dick Hemingway is indebted t. o the staff of the Alexandria Forest.

Available in PDF, EPUB and Kindle. Book excerpt: During the last few years, industrial fermentation technologies have advanced in order to improve the quality of the final product. Some examples of those modern technologies are the biotechnology developments of microbial materials, such as Saccharomyces and non-Saccharomyces yeasts or lactic bacteria from different genera. Other technologies are related to the use of additives and adjuvants, such as nutrients, enzymes, fining agents, or preservatives and their management, which directly influence the quality and reduce the risks in final fermentation products. Other technologies are based on the management of thermal treatments, filtrations, pressure applications, ultrasounds, UV, and so on, which have also led to improvements in fermentation quality in recent years. The aim of the issue is to study new technologies able to improve the quality parameters of fermentation products, such as aroma, color, turbidity, acidity, or any other parameters related to improving sensory perception by the consumers. Food safety parameters are also included.
