Book Description
The second international symposium on Pectins and Pectinases was organised by Wageningen University and Research Centre and was held in Rotterdam, May 6-10, 2001. This fruitful meeting was attended by around 130 participants from more than 20 countries, representing almost all of the groups/industries working worldwide on pectins and pectinases. Following the first meeting on this subject held in December 1995, the symposium definitely forms a platform for researchers and industries working in the field, all within their own discipline and expertise. The symposium book contains most keynote lectures and other oral presentations and provides an update about the current research. It is clearly demonstrated that significant progress has been made during the past seven years. The progress in the elucidation of the chemical structure of pectin and mode of action and 3-D structure of the pectin-degrading enzymes allows us more and more to identify (and influence) the functionality of pectins and pectic enzymes, both in vitro after isolation as well as in the plants themselves (in planta). Other contributions deal with new applications of both pectin and pectin-degrading enzymes, while more and more attention is paid to health and nutritional aspects of pectins.

Book Description
Pectins are one of the classes of complex structural plant cell wall polysaccharides. They are localized in the middle lamella and primary cell wall of higher plants. Pectins have a long-standing use as gelling agents whereas their enzymatic degradation or modification plays an important role in the processing of agricultural crops and the manufacturing of foods and beverages. Progress in pectin and pectinase research has been most prominent in two areas over the past 5 years. The first one concerns the analysis and elucidation of the complex chemical structure of pectin and identification of novel enzymes involved in the degradation of these structures. The second area concerns the mode of action and the 3-dimensional structure of various pectin degrading enzymes as well as the cloning of a large number of genes encoding enzymes involved in pectin degradation and modification. This book covers the following topics. First the structural, physical and chemical properties of pectin are treated followed by information about its biosynthesis and about the biological effects of pectin and its degradation products in biological systems such as plant-pathogen interactions and human nutrition. Identification of novel enzymes, the mode of action of different pectinases and the 3-D structure of bacterial pectate lyases forms the second block. This is followed by the genetics and regulation of pectinase biosynthesis in saprophytic and phytopathogenic microbial systems as well as in plant systems. Finally, developments in pectin manufacturing and application of pectinases in traditional (food, beverage) and novel technologies are treated. This book is meant for those actively involved in fundamental and applied aspects of pectin and pectinase research but it is also of value for those interested in plant cell wall biosynthesis and architecture, phytopathology, food technology and human nutrition. This book not only reflects the present status of research in the field but it will turn out to be a very useful reference work as well.

Book Description
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.

Book Description
Wineries are facing new challenges due to actual market demands for the creation of products exhibiting more particular flavors. In addition, climate change has lead to the requirement for grape varieties with specific features, such as convenient maturation times, enhanced tolerance towards dryness, osmotic stress, and resistance against plant-pathogens. The next generation of yeast starter cultures should produce wines with an appealing sensory profile and less alcohol. This Special Issue comprises actual studies addressing some of the problems and solutions for the environmental, technical, and consumer challenges of wine making today: Development of sophisticated mass spectroscopic methods enable the identification of the major metabolite spectrum of grapes/wine and deliver detailed insights in terroir and yeast-specific traits;Knowledge of the origin and reactions of reductive sulphur compounds facilitates the avoidance of unpleasant wine odors;Innovative physical–chemical treatments support effective and sustainable color extraction from red grape varieties;Enological enzymes from yeasts used directly or in the form of starter cultures are promising tools to increase the juice yields, color intensity, and aroma of wine;Natural and artificial Saccharomyces hybrids as well as collections of adapted wild isolates from various ecological niches will extend winemakers repertoire, allowing individual fermentations;Exact process control of wine fermentations by convenient computer programs will guarantee consistently high product quality.
