Reticulated Cellulose Gum meaning

I want to know what “Reticulated Cellulose Gum” means, which appears on the 25mg Zinc label.

R/Reticulated Cellulose Gum is an anti-caking agent (excipient or inactive ingredient that has no contribution or nutritional value), which is used to ensure that the tablets dissolve within a specific time, helping in their decomposition. In the case of Zinc 25 mg the disintegration time is less than one hour.
