Pollen and Spores


Book Description







Pollen Chemistry & Biotechnology


Book Description

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.




Method and Theory in Paleoethnobotany


Book Description

Paleoethnobotany, the study of archaeological plant remains, is poised at the intersection of the study of the past and concerns of the present, including agricultural decision making, biodiversity, and global environmental change, and has much to offer to archaeology, anthropology, and the interdisciplinary study of human relationships with the natural world. Method and Theory in Paleoethnobotany demonstrates those connections and highlights the increasing relevance of the study of past human-plant interactions for understanding the present and future. A diverse and highly regarded group of scholars reference a broad array of literature from around the world as they cover their areas of expertise in the practice and theory of paleoethnobotany—starch grain analysis, stable isotope analysis, ancient DNA, digital data management, and ecological and postprocessual theory. The only comprehensive edited volume focusing on method and theory to appear in the last twenty-five years, Method and Theory in Paleoethnobotany addresses the new areas of inquiry that have become central to contemporary archaeological debates, as well as the current state of theoretical, methodological, and empirical work in paleoethnobotany.

Paleoethnobotany


Book Description

This new edition of the definitive work on doing paleoethnobotany brings the book up to date by incorporating new methods and examples of research, while preserving the overall organization and approach of the book to facilitate its use as a textbook. In addition to updates on the comprehensive discussions of macroremains, pollen, and phytoliths, this edition includes a chapter on starch analysis, the newest tool in the paleoethnobotanist's research kit. Other highlights include updated case studies; expanded discussions of deposition and preservation of archaeobotanical remains; updated historical overviews; new and updated techniques and approaches, including insights from experimental and ethnoarchaeological studies; and a current listing of electronic resources. Extensively illustrated, this will be the standard work on paleoethnobotany for a generation.
