Available in PDF, EPUB and Kindle. Book excerpt: R. S. SHALLENBERGER Cornell University, New York State Agricultural Research Station, New York, USA Among the material to be discussed in this first section of the 'Enzymes and Food Processing Symposium' is subject matter that can be viewed as a marriage between enzyme technology and sugar stereochemistry. In order to bring the significance of the material to be presented into proper perspective, I would like you to pretend, for a moment, that you are a researcher making a proposal on this subject to a Research Granting Agency in order to obtain financial support for your ideas. However, the year is 1880. Under the 'objectives' section of your proposal, you state that you intend to attach the intangible vital force or spirit-that is, the catalyst unique to the chemistry of living organisms-to an inert substrate such as sand. Thereafter you will pass a solution of right handed glucose (also known as starch sugar) past the 'vital force' and in the process convert it to left-handed glucose (also known as fruit sugar). The peer review committee would probably reject the proposal as sheer nonsense because the statements made were not only contrary to their experience, but also contrary to what they had been taught. Perhaps a few select people would have some feeling for what you were talking about, but commiseration would be the only form of support that they could offer.

Download or read book Pectins and pectinases written by H.A. Schols and published by BRILL. This book was released on 2023-09-04 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Microbial Enzymes and Biotechnology written by W.M. Fogarty and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotechnology is now one of the major growth areas in science and engineering and within this broad discipline enzyme technology is one of the areas earmarked for special and significant developments. This publication is the second edition of Microbial Enzymes and Biotechnol ogy which was originally published in 1983. In this edition the editors have attempted to bring together accounts (by the relevant experts) of the current status of the major areas of enzyme technology and specifically those areas of actual and/or potential commercial importance. Although the use of microbial enzymes may not have expanded at quite the rate expected a decade ago, there is nevertheless intense activity and considerable interest in the whole area of enzyme technology. Microbial enzymes have been used in industry for many centuries although it is only comparatively recently that detailed knowledge relating to their nature, properties and function has become more evident. Developments in the 1960s gave a major thrust to the use of microbial enzymes in industry. The commercial success of alkaline proteases and amyloglucosidases formed a bed-rock for subsequent research and development in the area.

Download or read book Plant Cell Walls written by Nicholas C. Carpita and published by Springer. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a comprehensive collection of articles that cover aspects of cell wall research in the genomic era. Some 2500 genes are involved in some way in wall biogenesis and turnover, from generation of substrates, to polysaccharide and lignin synthesis, assembly, and rearrangement in the wall. Although a great number of genes and gene families remain to be characterized, this issue provides a census of the genes that have been discovered so far. The articles comprising this issue not only illustrate the enormous progress made in identifying the wealth of wall-related genes but they also show the future directions and how far we have to go. As cell walls are an enormously important source of raw material, we anticipate that cell-wall-related genes are of significant economic importance. Examples include the modification of pectin-cross-linking or cell-cell adhesion to increase shelf life of fruits and vegetables, the enhancement of dietary fiber contents of cereals, the improvement of yield and quality of fibers, and the relative allocation of carbon to wall biomass for use as biofuels. The book is intended for academic and professional scientists working in the area of plant biology as well as material chemists and engineers, and food scientists who define new ways to use cell walls.

Download or read book Advances in Pectin and Pectinase Research written by Fons Voragen and published by Springer. This book was released on 2013-03-09 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
