The PhEur 2005 provides monographs on acacia and spray-dried acacia, while the USPNF 23 describes acacia in a single monograph that encompasses tears, flakes, granules, powder, and spray-dried powder. The JP 2001 also has monographs on acacia and powdered acacia. See Table II. 

Solubility soluble 1 in 20 of glycerin, 1 in 20 of propylene glycol, 1 in 2.7 of water practically insoluble in ethanol (95%). In water, acacia dissolves very slowly, although almost completely after two hours, in twice the mass of water leaving only a very small residue of powder. The solution is colorless or yellowish, viscous, adhesive, and translucent. Spray-dried acacia dissolves more rapidly, in about 20 minutes. 

Gum acacia is a unique polysaccharide, with some peptides as part of the structure and has a range of different uses. It was originally the gum in gum sweets although some gum sweets do contain modified starch as a substitute. The replacement of gum is not because the substitute performs better but because there have been supply problems with gum acacia. Gum acacia is likely to be encountered in bakeries in small quantities when it has been used to make emulsions of citrus oils as a bakery flavour. It is possible to use gum acacia in making dry flavours from oils such as citrus by making an emulsion and then spray drying it. 

Some gum users now take gum in a pre-prepared form. Spray dried gum acacia has been used in pharmaceutical products for some time. The spray dried gum offers the pharmaceutical manufacturer a clean ready to use product. Instant forms of gum acacia have been offered by suppliers for some time. The instant products can be rapidly made into solution and used. Obviously the instant gum is more expensive. A manufacturer that uses gum as a minor ingredient may well find that the capital and labour cost of purifying raw gum is not cost effective. A company that uses gum acacia as a major ingredient might come to a different conclusion. Instantised gums pose different problems to the analytical chemist.. One approach that can be used is to have an optical rotation specification for the product. Even this approach is not entirely proof against a material that contains a blend of gums of different optical rotation. 

One of the primary variables which influences the recoveries of volatile flavor and aroma chemicals during spray drying is the wall material. Utilization of spray dried flavors in food systems presents further constraints on the wall material selection process. Of the food grade polymers available to the manufacturer of spray dried flavorings (i.e., gum acacia, lipophilic starches, maltodextrins, corn syrup solids), no single wall material exhibits the ideal traits deemed necessary for this economically important process. 

If the quantity of oil to be fixed in a dried powder is a parameter dependent on the end use, the formulator can choose between different Acacia gums. With a traditional Acacia gum (exudate of Acacia Senegal), a dry substance value of 35% represents a maximum value before spray drying. Beyond this value the emulsion viscosity is too high and drying inside the atomization tower does not take place satisfactorily. 

A recent study has been performed on various spray dried orange flavors(20% oil fixed in the powder) encapsulated on various Acacia gums and on mixtures of Acacia gums and malto-dextrins. The aromas in powder were tested by chromatography and then examined by electronic microscopy. This clearly shows the regular and uniform film covering each particle 10 to 40 microns in diameter. Prints of broken particles reveal numerous oil droplets (1 micron in diameter) spread in a gum nucleus. Protection of the oil phase then becomes fully effective. 

Polymers may be induced to encapsulate other molecules by a variety of means (Risch and Reineccius, 1995) as diverse as dipping, spray-drying, extrusion, evaporation, and coacervation each technique has its special applications, strengths, and weaknesses. Advantages in common are the protection and slow release of the encapsulate. In any of the mechanisms, a coagulable polymer precipitates around a core of labile material. Polysaccharides are regular encapsulating polymers (Risch and Reineccius, 1995) acacia gum is particularly efficacious because of its protein content. 

Gum arabic is an exudate of acacia trees, of which there are many species distributed over tropical and subtropical regions. The most important growing area for species that give the best gum is in Sudan. Purified, spray-dried forms of gum arabic are commonly used. 

Acacia is also used in cosmetics, confectionery, food products, and spray-dried flavors. ... 

Acacia is available as white or yellowish-white thin flakes, spheroidal tears, granules, powder, or spray-dried powder. It is odorless and has a bland taste. 

The bark of the tree is incised and the exudate allowed to dry on the bark. The dried exudate is then collected, processed to remove bark, sand, and other particulate matter, and graded. Various acacia grades differing in particle size and other physical properties are thus obtained. A spray-dried powder is also commercially available.

The objective was to encapsulate a vegetable oil (representing a model for aroma compound) into a powder. The oil (ISI04) (VO) will be at a concentration of 5% TS into a matrix made of maltodex-trin MD (DE 12) and acacia gum (AG) (3/2 MD/AG). The composition of matrix was defined in a previous research work on encapsulation of aroma by spray-drying (Bhandari et al., 1992 Turchiuli et al, 2005 Fuchs et al, 2006).
