| Abstract: |
A method is provided for treating gum base to improve its resistance to oxidation without the need for antioxidants wherein air or oxygen is swept from the gum base by means of an inert gas, and the oxygen-free gum base, in particulate form, is coated with a highly oxygenated substance, such as molten sugar, sorbitol solution or hydrogenated starch hydrolysate which acts as a barrier against oxygen. The gum base produced by the above method and chewing gum containing such gum base are also provided.

What is claimed is:
1. A method for treating gum base to improve its resistance to oxidation without the need for amounts of antioxidants normally employed, which comprises placing gum base in a confined area, heating the gum base at a temperature to melt the gum base, while the gum base is in a molten state applying a vacuum of from about 20 to about 29 in. Hg thereto to withdraw gases therefrom, removing the vacuum and introducing an inert gas under a pressure of 1 to about 5 psi into contact with the gum base and reapplying the vacuum thereby causing the inert gas to help sweep out air or oxygen remaining absorbed in the gum base after the first vacuum application.
