Gum arabic glycoprotein is a twisted hairy rope : a new model based on o-galactosylhydroxyproline as the polysaccharide attachment site.
Separation of the wound exudate from Acacia senegal (L.) Willd., "gum arabic," on a preparative Superose-6 column gave two major fractions: a high molecular weight gum arabic glycoprotein (GAGP) containing about 90% carbohydrate and a lower molecular weight heterogenous gum arabic polysaccharide fraction. Hydrogen fluoride-deglycosylation of GAGP gave a large ( approximately 400 residue) hydrox...
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...
متن کاملGum Arabic as a Cause of Occupational Allergy
Background. Gum arabic is a potential sensitizer in food industry. Methods. We examined 11 candy factory workers referred to examinations due to respiratory and skin symptoms paying attention to exposure and sensitization to gum arabic. Skin tests, pulmonary function tests, and respiratory provocation tests were carried out as indicated by the symptoms and findings. Results. Occupational asthma...
