Gums, resins and latexes are a most widely used and traded category of non-wood forest products. The uses of gums embrace food, pharmaceutical and miscellaneous technical applications. Resins have an equally diverse range of applications including their use in paints, varnishes and lacquers, and flavours and fragrances. Latexes are used in specialised applications such as insulating materials and in the manufacture of golf balls and chewing gum. There has been a decline in their use due to competition from synthetic products. This document contains a review of the production, markets and developmental potential of a number of gums, resins and latexes.
This publication is intended to serve researchers and teachers as well as development practitioners. It was prepared based on requests from CIFORs national partners in Ethiopia and the region to compile existing information and help address the lack of documents available for teaching graduate and undergraduate students about the management of forests in dryland areas in general, and the production and marketing of gums and resins in particular.
This reference book provides a comprehensive overview of natural gums, resins, and latexes of plants with a focus on their chemistry, biological activities, and practical uses. The content is divided into five main sections each of which contains chapters contributed from valuable experts in their field. Naturally occuring plant products have quite diverse applications in many different industries. The book aims to highlight the important aspects of plant-based gums, resins and latexes as well as provide a strategic framework for further research and development activities on these bioproducts. It will appeal to a broad audience such as biologists, pharmacologists, pharmacists, food technologists and medical practitioners. It is also a useful resource for research investigators of the healthcare industry, academia and students of biomedical sciences.

Resins, gums and latex are almost ubiquitous in the plant kingdom and many of them continue to play an important role in our daily lives. Numerous plants produce some kind of resin, latex or gum, but only a few are commercially important today, even though their uses and applications are truly manifold. They have been used as adhesives, emulsifiers, thickening agents, they are added to varnishes, paints and ink; they lend their aromas to perfumes and cosmetics and even play a role in pharmacy and medicine. Gums are viscous substances which are secreted by the bark of certain trees. Usually transparent (but sometimes slightly tinted) they contain a mucilage which when dissolved in water makes...
