Download or read book Pollen Chemistry Biotechnology written by Nesrin Ecem Bayram and published by Springer Nature. This book was released on 2024-01-17 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollen is made up of many chemical constituents such as proteins, sugars, lipids, minerals and phytochemicals. These components make pollen products an excellent source of nutrients and antioxidants for consumers. However, mycotoxigenic fungi are also common in pollen, creating contamination from generated mycotoxins. With adequate monitoring, sampling, processing and storage of pollen the development of mycotoxins can be significantly prevented. Since pollen grain has strong membranes which can limit the bioavailability of some nutrients and phytochemicals, novel methods and pretreatments are required with special emphasis on microbiological pretreatment methodologies. Pollen Chemistry & Biotechnology summarizes current knowledge of the chemical composition of pollen, its importance as a functional food ingredient and its health promoting properties. As Introduction part a short elaborate about botanical characteristics and data, including morphology and anatomy of pollen and bee preferences, is given. Important factors such as the botanical and geographical origin, best practices for preservation of nutritional composition, bioactivity and safety of pollen are covered in full. The nutritional profile of pollen based on data for minerals, lipids and nutrients is presented. A detailed phytochemical profile of pollen based on data for phenolics, flavonoids, carotenoids, vitamins, bioactive compounds is also covered. Areas for the improvement of the bioavailability of different nutrients and bioactive compounds of pollen via applied pretreatments are presented, as are best practices for adequate pollen collection, procession and storage in order to obtain safe products. At the end, an overview about pollen bioactivity as reason to use it as source of pharmaceuticals is made.
Download or read book Bee Products written by Avshalom Mizrahi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature .and diversity of presentations at the conference on: "Bee Products: Prop erties, Applications and Apitherapy" held at Tel-Aviv on May 26--30, 1996, emphasize the increasing interest of physicians, practitioners, scientists, herbalists, dieticians, cosmeti cians, microbiologists, and beekeepers in different facets of bee products. This volume consists of a selection of 31 contributions presented at the conference and which provide information on the present status of our knowledge in this area. In spite of their diversity, they reflect the mainstream of the conference, namely: "Imported" Prod ucts (honey, pollen and propolis), Exocrine Secretions of Workers (venom, royal jelly). Toxicity and Contaminants, Quality Control, Marketing, Apitherapy, Cosmetics, etc. Since antiquity, honey as well as other bee products were used as food, as a cure for ailments of humans and animals, and as cosmetics. We hope that this volume will contribute to interdisciplinary studies on chemical composition, pharmacological effects, nutrition, and other aspects of bee products. Critical and unbiased experimental research may unravel the yet unknown composition and mode of action of bee products and elucidate many unanswered questions. The noteworthy features of this conference were the participants from all parts of the world and of different cultural backgrounds, who shared their keen interest and curios ity regarding honey bees and their products. We thank all of them for their personal con tribution to the success of this conference.

Download or read book Melissopalynology of East Texas written by Gretchen Drake Jones and published by . This book was released on 1993 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyses were made to compare different techniques of pollen extraction and to investigate the pollen contents of East Texas honey. A new alcohol technique for diluting honey is described, and pollen recovery of honey samples diluted with water and alcohol using different centrifugation times was examined. Pollen concentrations of alcohol-diluted samples were significantly higher than those of water-diluted samples. There was no significant difference in the number of pollen taxa recovered between the water long spin technique, and the alcohol technique, however, there was a significant difference between pollen recovery of the water short spin technique versus the alcohol technique. Five samples were compared using the alcohol dilution technique to a new filter technique. No significant difference was found in pollen recovery or concentration values between the two techniques. Pollen counts of 400 or 500 pollen grains yielded significantly more taxa than lesser counts. Taxa in frequency classes remained constant for most pollen types between 200 and 500 grain counts. Variation among five different drops of the same sample was investigated using 200, 300, 400, and 500 pollen grain counts. No significant differences were found in pollen concentration, but each successively higher count had significantly more taxa. Pollen was analyzed from 36 East Texas honeys samples. A total of 431 pollen types (including unknowns) were found. Half of the samples contained between 31-40 pollen types, indicating a diverse botanical flora. Native flora contributed more to East Texas honey than did horticulturalized taxa. All samples, except two, were classified as mixed floral honeys. Berchemia scandens, Salix nigra, and Toxicodendron radicans were found in more than 80% of the East Texas honey samples. Honeys from the northern regions of East Texas are characterized by Berchemia scandens, Ceanothus americanus, Nyssa sylvatica, Rhamnus caroliniana, Salix nigra, and three unknowns. The southern regions are characterized by Mimosa strigillosa, Berchemia scandens, Poaceae, and four unknowns. In general, East Texas honeys are characterized by a combination of Berchemia scandens, unknown 236, Rhamnus caroliniana, and Salix nigra. The most important honey bee floral resources in East Texas appear to be Rhamnaceae, especially Berchemia scandens.

Download or read book Applications of Non Pollen Palynomorphs written by F. Marret and published by Geological Society of London. This book was released on 2021-10-29 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.

Download or read book Applications of Palaeontology written by Robert Wynn Jones and published by Cambridge University Press. This book was released on 2011-08-18 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palaeontology, the scientific study of fossils, has developed from a descriptive science to an analytical science used to interpret relationships between Earth and life history. This book provides a comprehensive and thematic treatment of applied palaeontology, covering the use of fossils in the ordering of rocks in time and in space, in biostratigraphy, palaeobiology and sequence stratigraphy. Robert Wynn Jones presents a practical workflow for applied palaeontology, including sample acquisition, preparation and analysis, and interpretation and integration. He then presents numerous case studies that demonstrate the applicability and value of the subject to areas such as petroleum, mineral and coal exploration and exploitation, engineering geology and environmental science. Specialist applications outside of the geosciences (including archaeology, forensic science, medical palynology, entomopalynology and melissopalynology) are also addressed. Abundantly illustrated and referenced, Applications of Palaeontology provides a user-friendly reference for academic researchers and professionals across a range of disciplines and industry settings.
