Evaluation of gum exudates from three selected plant species from Tanzania for food and pharmaceutical applications

Abstract

Authenticated gum samples from three plant species from Tanzania were analysed and their potential for food, pharmaceutical and other applications was determined by comparing their physicochemical properties with those of commercial Acacia gums from Tanzania, gum karaya and the specifications demanded by the international regulatory bodies for gum arabic for food and pharmaceutical applications. The gum exudate from Dichrostachys cinerea meets some specifications (moisture content, solubility, insoluble matter and ash) demanded for the identity and purity of gum arabic as stipulated by the international regulatory bodies. The aqueous solution of the gum possesses solubility and viscosity similar to commercial gum arabic. Similarly, the properties of Sterculia quinqueloba gum meet a number of the specifications demanded for gum karaya, except that it contains high levels of tannin which would limit its usefulness in food and pharmaceutical applications. The properties of the gum exudate from Acacia pseudofistula, on the other hand, are different from those of Tanzanian commercial Acacia gums.

Searching for Dental Signals of Exudativory in Galagos

“…Note that all galago exudativores must have a diet that consists of nutrients other than exudates as exudates consist primarily of complex beta-linked carbohydrates and minerals with little to no proteins (Power, Chap. 2;Power and Oftedal 1996;Mbuna and Mhinzi 2003).…”

Natural polysaccharide functionalized gold nanoparticles as biocompatible drug delivery carrier

“…Gum karaya (GK) is the dried exudates obtained from Sterculia urens Roxd and other related species of Sterculia (family Sterculiaceae) or Cochlospermum gossypium AP De Candolle or other species of C kunth (family Bixaceae). GK is partially acetylated polysaccharide with a molecular weight of about 16 × 10 9 Da, anionic in nature and on hydrolysis it produces rhamnose, galactose, galactouronic acid and glucuronic acid [21,22]. Because of its non-toxic nature, low-cost and easy availability, it has been found to have wide applications in food and pharmaceutical industries as binder, viscofier, food additive and emulsifier and as drug release modifier in the design of oral controlled release formulations [23][24][25].…”

Chemical Defenses in Eucalyptus Species: A Sustainable Strategy Based on Antique Knowledge to Diminish Agrochemical Dependency

“…Pharmaceutical industry uses gums as binding agents for tablets production, and as emulsifying agents in creams and lotions. Food and printing industries have also taken advantage of their thickening, emulsifying, and stabilizing characteristics (Mbuna and Mhinzi 2003, Gentry et al 1992, Anderson 1993. Rosin derivatives from pine trees are being used alone or in combination with acrylic resin solutions and emulsions to produce better quality water-based flexographic inks and varnishes (Vernardakis 2009).…”

“…Rosin derivatives from pine trees are being used alone or in combination with acrylic resin solutions and emulsions to produce better quality water-based flexographic inks and varnishes (Vernardakis 2009). Resins are used for paper, wood paints production, and also to prepare varnishes and lacquers, whereas soft resins and balsams are used to produce fragrances (Mbuna andMhinzi 2003, Messer 1990). Latexes have been early used in the chewing gum industry (Williams 1963).…”
