This text presents the technological and physiological properties of pectin in an educational approach that encompasses all of the essential information a researcher needs to fully understand their function and use in foods. Utilizing basic information on pectin as well as recent technological advances, this book is designed to be the primary resource for individuals seeking out an up to date reference work covering all the necessary informational and functional aspects of pectin. Pectin: technological and physiological properties is the first book to fully focus on the introductory concepts on pectin. Individual chapters cover localization and function, the structural aspects of pectin, pectinases, isolation and characterization and recovery from agricultural wastes. Important current advances such as emulsions, films, digestion, metabolism and bioactive properties are also focused on. With its combination of vital basic information and technological advances, this book presents full and up to date coverage on this pectin and its many forms and uses in foods.
A fundamental understanding of polymers has evolved in recent years concurrent with advances in analytical instrumentation. The theories and methodologies developed for the galacturonan biopolymers (collectively called pectins) have seldom been discoursed comprehensively in the context of the new knowledge. This text explains the scientific and technical basis of many of the practices followed in processing and preparing foods fabricated with or containing pectin. The material is presented in a very readable fashion for those with limited technical training.

A comprehensive guide to home preserving and canning in small batches provides seasonally arranged recipes for 100 jellies, spreads, salsas and more while explaining the benefits of minimizing dependence on processed, store-bought preserves.
Pectin extracted from suitable plant sources is used as food ingredient for its gelling, stabilizing and thickening functionalities. Pectic substances also have a great impact on the quality of fresh and processed foods particularly fruits and vegetables. Plant products, fresh, extracted or processed, constitute a large part of the human diet. As a fibre, naturally present in these food products, pectic substances fulfil a nutritional function and are increasingly of interest as a health promoting polysaccharide. Pectin is one of the major components of the cell wall of dicotyledonous plants and probably one of the most complex macromolecules in nature. This book provides an update account of the most significant state of the art research on pectin and demonstrates that significant progress has been made in recent years. The book addresses progress made in the fields of biosynthesis and health modulating activities of pectin fractions, among other things. Research reported uses the most advanced current spectroscopic techniques and immunodetection methods combined with microscopy and chromatography, genomics of pectic enzymes of Aspergillus niger, and interaction of pectins with proteins. The progress documented in this book allows us to increasingly identify and influence the functionality of pectins and pectic enzymes both in vitro after isolation, as well as in the plants themselves. This knowledge is also reflected in new applications of pectin and pectin degrading enzymes. 'Pectins and Pectinases' is of interest to beginning and advanced researchers and food specialists in academic and commercial food industry settings globally.
Pectins are biopolymers with multiple applications because of their structural diversity and complexity. Although pectins from different sources have some common structural characteristics, many aspects of the common structure change according to the species and the physiological stage of the plant. Moreover, the application of pectin is determined by its chemical features, including galacturonic acid content, methoxyl content, degree of esterification and acetyl value. The most traditional raw materials used for the extraction of pectins are either apple pomace or citrus peels that are supplied as by-products of juice production. Both materials contain significant amounts of pectic substances, but with different chemical characteristics that make them suitable for specific applications. Considering that pectin is widely used as a functional ingredient, many researchers have been testing the use of other materials and alternative methods of extraction for industrial exploitation. This book discusses the chemical properties of pectin. It addition, it includes the uses and health benefits that pectin may have.
2015 IACP Award Winner, Best Single Subject Cookbook A householder's guide to canning through the seasons. In Mrs. Wheelbarrow's Practical Pantry, food preserving expert Cathy Barrow presents a beautiful collection of essential preserving techniques for turning the fleeting abundance of the farmers’ market into a well-stocked pantry full of canned fruits and vegetables, jams, stocks, soups, and more. As Cathy writes in her introduction, “A walk through the weekend farmers’ market is a chance not only to shop for the week ahead but also to plan for the winter months.” From the strawberries and blueberries of late spring to the peaches, tomatoes, and butter beans of early fall, Mrs. Wheelbarrow’s Practical Pantry shows you how to create a fresh, delectable, and lasting pantry—a grocery store in your own home. Beyond the core techniques of water-bath canning, advanced techniques for pressure canning, salt-curing meats and fish, smoking, and even air-curing pancetta are broken down into easy-to-digest, confidence-building instructions. Under Cathy’s affable direction, you’ll discover that homemade cream cheese and Camembert are within the grasp of the weekday cook—and the same goes for smoked salmon, home canned black beans, and preserved and cured duck confit. In addition to canning techniques, Practical Pantry includes 36 bonus recipes using what’s been preserved: rugelach filled with apricot preserves, tomato soup from canned crushed tomatoes, arugula and bresaola salad with Parmigiano-Reggiano and hazelnuts, brined pork chops with garlicky bok choy. Tips for choosing the best produce at the right time of season and finding the right equipment for your canning and cooking needs—along with troubleshooting tips to ensure safe preserving—will keep your kitchen vibrant from spring to fall. Whether your food comes by the crate, the bushel, or the canvas bag, just a few of Cathy’s recipes are enough to furnish your own practical pantry, one that will provide nourishment and delight all year round. Canning and preserving is not just about the convenience of a pantry filled with peaches, dill pickles, and currant jelly, nor is it the simple joy of making a meal from the jars on the shelf—creating a practical pantry is about cultivating a thoughtful connection with your local community, about knowing exactly where your food comes from and what it can become.
This book deepens the study and knowledge on pectins, especially in the processes of extraction, purification, and characterization, in short its many and wide applications. Among the most prominent applications are the food, pharmaceutical, and other industries. The development of pectins has a very promising future with a marked annual increase and with a wide range of sources. As written above, this book will help its readers to expand their knowledge on this biopolymer with vast application in the industry worldwide.
This fourth volume in the Chemical and Functional Properties of Food Components series focuses on saccharides as food constituents. Written by an international group of experts, it provides an up-to-date review of a wide spectrum of issues, focusing on the current research and literature on the properties of compounds, their mechanisms of action, a
Pectin is an industrial product of certain fruit peels that contain it, such as citrus fruits, apples, pears, grapes, plums, beets, sunflowers, and so on. It is the traditional gelling agent for jams and jellies, but its applications extend to fruit products for food, dairy, dessert, soft drink, pharmaceutical, and other industries. This book discusses pectin production, pectin biotechnology, and pectin applications. Chapters cover such topics as the production of pectin from citrus, fungal pectinases in food technology, pharmaceutical applications of pectin, and more.
