Exudate gums stabilizers

Gum, arabic. This thickening agent used for stabilizing emulsions is made from the dried exudate of the stems of the Acacia Senegal. 

Already the ancient Egyptians knew that one can keep soot particles dispersed in water when they were incubated with gum arabicum, an exudate from the stems of acaia trees, or egg white. In this way ink was made. The reason for the stabilizing effect is the steric repulsive force cause by adsorbed polymers. In the first case these are a mixture of polysaccharide and plycoprotein, in the second case it is mainly the protein albumin. Steric stabilisation of dispersions is very important in many industrial applications. Direct quantitative measurements were... 

Gum arabic is widely used as an emulsifier in the beverage industry to stabilize cloud and flavor emulsions [98]. It is derived from the natural exudate of Acacia Senegal, and consists of at least three high molecular weight biopolymer fractions The surface-active fraction is believed to consist of branched arabinogalactan blocks attached to a polypeptide...
