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 Pot Pollen in Stingless Bee Melittology written by Patricia Vit and published by Springer. This book was released on 2018-03-05 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers pot-pollen—the other product, besides honey, stored in cerumen pots by Meliponini. Critical assessment is given of stingless bee and pot-pollen biodiversity in the Americas, Africa, Asia and Oceania. Topics addressed include historical biogeography, cultural knowledge, bee foraging behavior, pollination, ecological interactions, health applications, microbiology, the natural history of bee nests, and chemical, bioactive and individual plant components in stored pollen. Pot-pollen maintains the livelihoods of stingless bees and provides many interesting biological products that are just now beginning to be understood. The Meliponini have developed particular nesting biologies, uses of building materials, and an architecture for pollen storage. Environmental windows provide optimal temperature and availability of pollen sources for success in plant pollination and pollen storage. Palynological composition and pollen taxonomy are used to assess stingless honey bee pollination services. Pollen processing with microorganisms in the nest modifies chemical composition and bioactivity, and confers nutraceutical benefits to the honey and pollen widely relished by native people. Humans have always used stingless bees. Yet, sustainable meliponiculture (stingless bee-keeping) projects have so far lacked a treatise on pot-pollen, which experts provide in this transdisciplinary, groundbreaking volume.

Download or read book Food Authentication written by Philip R. Ashurst and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issue of food authenticity is not new. For centuries unscrupulous farmers and traders have attempted to 'extend', or othewise alter, their products to maximise revenues. In recent years the subject has reached new prominence and there even have been situations where food authenticity has featured as a newspaper headline in various countries. Food legislation covering the definition, and in some cases composition, of various commodities has been in place in developed countries for many years and paradoxically it is the legislative trend away from emphasis on composition and more on accurate and truthfullabeliing that has been one driving force for the authenticity issue. Another, and many would speculate as the more potent, driving force is the move towards fewer and larger supermarket chains in many countries. Such trading companies with their images of quality products, buying power and commercial standing, exercise considerable commercial power which has been claimed as a significant source of financial pressure on food prices and food commodity product quality. For whatever reason, recent food authenticity issues have become news and consumers, the media and enforcement authorities are showing more interest than ever before in the subject.

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.
