TL;DR: In this article, the results showed that the interaction with an A. senegal specific antibody (SY CC7) is the same for the whole gum sample and its fractions, indicating a common, widely distributed epitope.

TL;DR: The amino acid profile for guar gum differs extensively from those for gum arabic and gum karaya; this provides a useful analytical supplement to sugar determinations for studies of admixtures of these hydrocolloids.
Abstract: Guar gum, powdered endosperm from the seeds of the legume Cyamopsis tetragonolobus, is a galactomannan which contains 2.5-4.5% of a proteinaceous component. Data presented for 11 bulk commercial samples show that the most abundant amino acids are glycine, glutamic acid, aspartic acid, serine and alanine, but that their relative proportions vary considerably. The proportions of other amino acids, e.g. histidine, isoleucine, phenylalanine, threonine, tyrosine and valine are remarkably constant. There appear to be some correlations between viscosity and the glycine, arginine and proline contents. Data for the amino acid compositions of several chemical derivatives of a medium-viscosity gum guar sample indicate that the proteinaceous component is retained but suffers variable modification. The amino acid profile for guar gum differs extensively from those for gum arabic and gum karaya; this provides a useful analytical supplement to sugar determinations for studies of admixtures of these hydrocolloids.

TL;DR: In this paper, the utility of gum Arabic (Acacia species) as film former (binder) in formulations was investigated and it was recommended that additives should be incorporated into gum Arabic solution in order to achieve high quality films.
Abstract: The utility of gum Arabic (Acacia Species) as film former (binder) in formulations was investigated. Some property such as blistering and scratch adhesion of the solutions of crude gum Arabic as a sole binder in formulations were investigated and compared to those of solutions of modified gum Arabic. From the work carried out, it was discovered that the quality of the film resulting from the solution of crude gum Arabic was poor. In order to improve the film forming ability of gum arabic, some additives such as plasticizers and cross-linking agents were incorporated. It was found that the solution of gum Arabic with plasticizer and cross-linking agents incorporated gave a high quality film than that of the crude gum Arabic. It was recommended that additives should be incorporated into gum Arabic solution in order to achieve high quality films.

TL;DR: Powdered silver is produced by reacting an aqueous solution of silver nitrate with an alkali hydroxide to form a precipitate of silver oxide and reducing the precipitate by formaldehyde in the presence of a water soluble colloid e.g. gum arabic as discussed by the authors.
Abstract: Powdered silver is produced by reacting an aqueous solution of silver nitrate with an alkali hydroxide to form a precipitate of silver oxide and reducing an aqueous suspension of the precipitate by formaldehyde in the presence of a water soluble colloid e.g. gum arabic. The reduction may be effected in two stages (i) at a temperature of 20-40 DEG C. to form silver formate and (ii) at a temperature of 40-70 DEG C. to dissociate the silver formate and produce silver. Alternatively, the silver nitrate may be dissolved in water in the presence of formaldehyde and gum arabic and sodium or potassium hydroxide added at a temperature of 50-70 DEG C.
