A "soluble Specific Substance" Derived from Gum Arabic
1. By partial acid hydrolysis a specific carbohydrate may be isolated from gum arabic (gum acacia). This carbohydrate is comparable in its precipitating activity for Type II (and Type III) antipneumococcus serum with the bacterial soluble specific substances themselves. 2. On hydrolysis this fraction yields galactose and two or more complex sugar acids, one of which appears to be a disaccharide...
متن کاملIsolation of the aldobionic acid of umbilical cord hyaluronic acid.
In a preliminary note there was outlined the isolation of a crystalline glucuronido-glucosamine disaccharide, designated hyalobiuronic acid, from umbilical cord hyaluronate by combined enzymatic and partial mineral acid hydrolysis (1). In subsequent articles the use of this compound as a basis for structural work on the polysaccharide and as a reference point for interpretation of enzymatic dat...
متن کاملGum Arabic: More Than an Edible Emulsifier
Gum Arabic (GA) or Acacia gum is an edible biopolymer obtained as exudates of mature trees of Acacia senegal and Acacia seyal which grow principally in the African region of Sahe in Sudan. The exudate is a non-viscous liquid, rich in soluble fibers, and its emanation from the stems and branches usually occurs under stress conditions such as drought, poor soil fertility, and injury (Williams & P...
متن کاملHydrodynamic Properties of Whole Arabic Gum
The most economically important of the hydrodynamic properties of a material are viscosity and density, which allow determining the intrinsic viscosity of raw materials used in the food industry. They serve as an indirect measure of molecular weight (M), hydrodynamic radius (RH), number of Simha, (ν(P)), Perrin parameter (P); hydration value (δ), Scheraga-Mandelkern parameter (β), and Flory par...
متن کاملDecolourization of Gum Arabic using Activated Charcoal
This research work is aimed at decolourizing gum Arabic using activated charcoal so as to improve the quality of gum Arabic before the use of additives on the gum Arabic. The experiment was conducted on laboratory scale, the filter fixed bed method was used and the adsorbent (activated charcoal) is a granular of 500μm mesh size. The pH, viscosity and transmittance of each solution were measured...
