In the countries of destination, Gum Arabi is further processed into the forms required for incorporation into the finished goods. These procedures include granulating, powdering, spray drying, and “kibbling,” which produces pieces of a consistent pebble size. Kibbling is the process of running whole or sizable lumps of gum through a hammer mill and screening it to create smaller, more uniformly sized granules. The end user prefers these pieces over raw gum because they dissolve in water more readily and under more consistent conditions.
Transport and Storage: Jute or burlap sacks are used to store and export crude Gum Arabic. Each heavy duty bag holds about 80 kg of the graded gum. According to US regulations, only brand-new, unused jute sacks may be used. The semi-processed and processed kibbled variety, the granules, and the powdered Gum Arabi are exported in drums, multi-wall paper bags lined with polyethylene, or cardboard boxes lined with polyethylene. When kept in a cool, dry environment, Gum Arabi has an endless shelf life.
