Tracking of the post-compressional behaviour of chewing gum tablets

The elasticity and elastic recovery of chewing gum powder were tested in this work. Powder rheological tests (flowability and compressibility) showed that direct compression is a suitable method for the preparation of chewing gum tablets. The advantages of this method relative to preparation by extrusion are economic: a reduced processing time, fewer manufacturing steps, less equipment, less process validation and reduced labour costs. A very important property of a chewing gum tablet is the chewability, which depends on the elasticity of the product. This was tested by breaking strength measurements and study of the deformation process. For a good chewable tablet, the authors suggest application of a compression force of 5 kN.
