TL;DR: The Test Article is a fair, average representative sample of gum arabic originating from Acacia Senegal and conforming in all respects to established international standards of identity and purity as mentioned in this paper.
Abstract: SUMMARY The sample of commercial gum arabic used as the “Test Article” in recent toxicological studies has been characterized chemically. Comparative analytical data, presented for seven other commercial gum arabic samples, and for five specimens of gum collected from authenticated Acacia Senegal trees in several gum producing countries, indicate that the Test Article is a fair, average representative sample of gum arabic originating from Acacia Senegal and conforming in all respects to established international standards of identity and purity.

TL;DR: In this article, a bland colorless clouding agent is disclosed which comprises an emulsion of a glyceride fat, preferably cocoa butter or soy stearin, in an aqueous solution or dispersion of gum arabic.
Abstract: A bland, colorless clouding agent is disclosed which comprises an emulsion of a glyceride fat, preferably cocoa butter or soy stearin, in an aqueous solution or dispersion of gum arabic. The glyceride fat cloud emulsion contains from 10% to 30% by weight of gum arabic, a gum arabic to glyceride fat ratio of from 3:1 to 5:1 by weight, and a water content of 70% to 90% by weight, based upon the weight of the emulsion. The clouding emulsion is preferably incorporated into a citrus-flavored, ready-to-drink beverage and it will remain suspended for 4 months or longer. The ready-to-drink beverage will preferably be of a pH from 2.5 to 4 and contain a juice content of from 10% to 35%.

TL;DR: In this article, the gum exuded by a cultivar of Leucaena leucocephala growing in South India has been analysed and its analytical parameters indicate that it is similar to gum arabic.
Abstract: SUMMARY The gum exuded by a cultivar of Leucaena leucocephala growing in South India has been analysed. Its analytical parameters indicate that it is similar to gum arabic. The physico-chemical properties of aqueous solutions (good solubility, viscosity and colour) suggest that Leucaena gum would have useful commercial applications; its stability in acidic solutions is better than that of gum arabic.

TL;DR: The pseudoplastic condition of aqueous xanthan gum is reproduced in other less expensive gums used in the bakery trade for flan jellies and similar products, by a preparative method in which a heated solution of a polysaccharide gum is rapidly chilled as discussed by the authors.
Abstract: The pseudoplastic condition of aqueous xanthan gum is reproduced in other, less expensive gums used in the bakery trade for flan jellies and similar products, by a preparative method in which a heated solution of a polysaccharide gum is rapidly chilled. The pseudoplastic condition facilitates dispensing and application and the mobile fluid is stiffened in conventional manner to a gel by reheating and cooling. Preferred polysaccharide gums are locust bean gum, gum arabic, carrageenan, guar, furcelleran and agar.

TL;DR: In this paper, the authors proposed to prevent rise in viscosity and jellification by freezing fruits quickly, crushing them in a low-temperature atmosphere, and adding gum arabic to them in the thawing process.
Abstract: PURPOSE:To prevent rise in viscosity and jellification, by freezing fruits quickly, crushing them in a low-temperature atmosphere, adding gum arabic to them in a thawing process. CONSTITUTION:Fruits containing a pectic material and an organic acid are brought into contact with an inert refrigerant and quickly frozen. They are pulverized in a low-tempeature atmosphere, gum arabic in the state of powder is directly added to them in a thawing process or it is dissolved in a proper amount of water and the solution is added to them, and, if necessary, a saccharide is added to them. The processed food thus obtained has improved flow properties and fresh flavor, is easily and uniformly dispersed into water or other food raw materials, and has improved storage stability in frozen state, refrigerated state, or at normal temperature.
