TL;DR: In this article, improved gum arabic capable of providing an emulsified substance having improved antiseptic effect without causing anxious change such as formation of precipitate, separation phenomena, etc., by reducing ash and alkaline earth metals in gum arabbic.
Abstract: PURPOSE: Improved gum arabic capable of providing an emulsified substance having improved antiseptic effect without causing anxious change such as formation of precipitate, separation phenomena, etc., by reducing ash and alkaline earth metals in gum arabic. CONSTITUTION: Gum arabic powder is added to cold water or warm water to give an aqueous solution, which is desalted until ash in the gum arabic becomes ≤2wt%, preferably ≤0.1wt% and alkaline earth metals become ≤3.0g/kg, preferably ≤1.0g/kg by ion exchange method, etc., to give the desired gum arabic.

TL;DR: In this paper, a polysaccharide derivative is obtained by reacting a poly-saccharides which is soluble or dispersible in cold or hot water with a sultone in the presence of an alkaline substance.
Abstract: Polysaccharide derivatives are obtained by reacting a polysaccharide which is soluble or dispersible in cold or hot water with a sultone in the presence of an alkaline substance. The sultones may be 1, 3-propanesultone, 1, 4-butanesultone, mixtures of isomeric butanesultones, benzylsultone and tolylsultone; preferably, g -sultones are used. The polysaccharide may be starch in its natural form, or dextrinated, acid-modified, thin-boiling, oxidized, etherified, or esterified starch, or amylose or amylopectin; specified starches are those of corn, wheat, potato, tapioca, waxy corn, sago, or rice. Natural plant hydrocolloids such as gum arabic, gum tragacanth, carob gum, guar gum or alginates may also be used. The sultones may be reacted with the air-dry polysaccharide and the product used without further processing, or reaction may be effected in suspension or solution in a liquid and the product dried, e.g. by passing over a heated rotating cylinder. The resulting polysaccharide ether sulphonic acids and salts may be used as textile sizes, and for paper coating and sizing, as protective colloids in oil well drilling muds, and as adhesives. In a typical Example (No. 1) 2,000 parts, by weight, of potato starch, 3,000 parts of water and 120 parts of NaOH were mixed at 60 DEG -70 DEG C. and 360 parts of g -propane sultone added over a period of 15 minutes and then the mass allowed to stand for 30 minutes. The resulting product containing the sodium salt of starch propane sulphonic acid was pressed on a heated rotated drum and then ground.

TL;DR: In this article, the formation of a gelled gravy in canned meat-containing products is prevented by the use of anionic polymers such as gum ghatti, gum arabic and xanthan which both inhibit protein extraction from the meat and prevent gelation in extracted protein which may be present in sufficient amounts to form gels upon cooling and/or storage.

TL;DR: In this article, a perfumed jelly candy which gives refreshing perfume to the mouth and masks foul breath when held in the mouth was created by adding a perfume to a gelable sol, and gelling the mixture.
Abstract: PURPOSE:To provide a perfumed jelly candy which gives refreshing perfume to the mouth and masks foul breath when held in the mouth, by adding a perfume to a gelable sol, and gelling the mixture. CONSTITUTION:A gelation raw material selected from gelatin, gum arabic, collagen, and polymeric polysaccharides capable of forming a gel, e.g. agar, pectin, etc., is incorporated with sugars, water, and if necessary, organic acid or its salt, seasonings, colorants, and other additives, and heated to obtain a sol. The sol is mixed with 1-10wt% of desired perfume, homogenized, and solidified to a desired shape.

10 Nov 2011TL;DR: Gum Arabic coated 198 Au nanoparticles have been demonstrated experimentally shown to have a surprising efficacy for a single dose direct injection, reducing tumors in analog mice by 82% over a short period of time.
Abstract: The invention provides a cancer therapeutic and imaging agent comprising a solution containing Gum Arabic coated 198 Au nanoparticles. The Gum Arabic coated 198 Au nanoparticles have been demonstrated experimentally shown to have a surprising efficacy for a single dose direct injection, reducing tumors in analog mice by 82% over a short period of time. The particles of the invention have a believed optimal size for therapy and imaging applications, and can be used as a theranostic agent in the treatment of needle accessible cancers. The invention also provides a method for forming Gum Arabic coated 198 Au nanoparticles. A gold foil is irradiated to produce 198 Au foil. The foil is dissolved to form radioactive gold salt. The salt is dried, and then reconstituted to form a 198 Au nanoparticle precursor. The precursor is reduced with a reducing agent in an aqueous solution including Gum Arabic to form Gum Arabic coated 198 Au nanoparticles.
