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.

Red Wine Enology - Tannin and Redox Management in Red Wines - addresses the very heart of red winemaking, which is the extraction of tannins and colored compounds as well as the subsequent measures of balancing oxygenation and reduction throughout elevage to achieve their optimal sensory expression. In a broad-ranging discussion of redox management, the authors address in a single volume the most important and yet the most controversial aspects of red wine enology. The reader is guided through basic phenol chemistry and analysis to the broadly accessible total phenol measurements facilitating appropriate redox management decisions. Building upon these foundations, the authors discuss the entire process of vinification - from maceration options through elevage and stabilization to bottling, clearly defining what measures to take and those to avoid. Barrel aging, oxygenation, and the role of yeast lees and SO2 are presented as part of a holistic approach to elevage as a multidimensional process. Where appropriate the text encompasses closely associated issues including oak alternatives, micro--oxygenation, control of spoilage microorganisms, adjustment of pre-bottling free SO2 to compensate for post-bottling SO2 losses, and the issue of the so-called natural wines. Due to the shear complexity of tannin chemistry, this book has a strong focus on sensory analysis throughout discussing appropriate redox strategies to preserve fruit in low-tannin wines and to optimize the ageability of high-tannin wines.

Tannins are one of the polyphenols group found in plants and are mainly studied because of their structural properties and bioactive behavior. Every year new findings concerning their properties and functions are made, and today concerns are mainly focused on how they can be used efficiently in the wood, food, textile, health, and pharmaceutical industries. Thus, the aim of this book is to present the most updated information on the structural properties of tannins, their food sources and variations, biological properties, and health, among other important issues. In addition, the most recent methods used for their isolation, quantifications, and industrial applications will also be covered.

While many books proliferate elucidating the science behind the transformations during cooking, none teach the concepts of physics chemistry through problem solving based on culinary experiments as this one by renowned chemist and one of the founders of molecular gastronomy. Calculating and Problem Solving Through Culinary Experimentation offers an appealing approach to teaching experimental design and scientific calculations. Given the fact that culinary phenomena need physics and chemistry to be interpreted, there are strong and legitimate reasons for introducing molecular gastronomy in scientific curriculum. As any scientific discipline, molecular gastronomy is based on experiments (to observe the phenomena to be studied) and calculation (to fit the many data obtained by quantitative characterization of the studied phenomena), but also for making the theoretical work without which no real science is done, including refuting consequences of the introduced theories. Often, no difficult calculations are needed, and many physicists, in particular, make their first steps in understanding phenomena with very crude calculations. Indeed, they simply apply what they learned, before moving to more difficult math. In this book, the students are invited first to make simple experiments in order to get a clear idea of the (culinary) phenomena that they will be invited to investigate, and then are asked simple questions about the phenomena, for which they have to transform their knowledge into skills, using a clear strategy that is explained throughout. Indeed, the is "problem solving based on experiments", and all this about food and cooking. Key Features: Introduces readers to tips for experimental work Shows how simple scientific knowledge can be applied in understanding questions Provides a sound method ("strategy") for calculation in physics and chemistry Presents important definitions and laws for physical chemistry Gives confidence in one’s calculation skill and problem solving skills Explore physical and chemical phenomena that occur during cooking A unique mix of culinary arts and correct calculations, this book is useful to students as well as professors in chemistry, physics, biology, food science and technology.
