Gums Acacia seyal

Gel permeation chromatography studies using both refractive index and UV(260 nm) absorption detections have confirmed that both Acacia Senegal and Acacia seyal gums consist of three main components (Islam et al., 1997, Idris et al., 1998, Williams Phillips, 2000, Al Assaf 2006) ... 

There is a need to have a testing regime to ensure that the gum acacia offered is gum acacia and not a product from some other species that is unsuitable. Acacia Seyal gum is sometimes encountered, which is less soluble than gum acacia and hence it is unsuitable for making sweets with a high proportion of gum acacia as it will not dissolve sufficiently. Instances have occurred where gum combretum, a product that is not an acacia gum, has been found in commercial supplies purporting to be gum acacia. 

Gum Arabic (GA) or Acacia gum is an edible biopolymer obtained as exudates of mature trees of Acacia Senegal and Acacia seyal which grow principally in the African region of Sahe in Sudan. The exudate is a non-viscous liquid, rich in soluble fibers, and its emanation from the stems and branches usually occurs under stress conditions such as drought, poor soil fertility, and injury (Williams Phillips, 2000).

Gum arabic (also known as gum acacia) is a natural plant gum, a dried exudate obtained from the stems and branches of Acacia Senegal or Acacia seyal or other Acacia species. ... 

Gum arabic (also called acacia gum) is hardened exudate from acacia tree species, in particular from Acacia Senegal and Acacia seyal (Fabaceae), growing mainly in Senegal, Nigeria and West African countries. There are over 100 different acacia gums, but the structural differences between them are small.
