Abstract

Anticariogenetic chewing gum containing a known chewing gum base, sodium fluoride, calcium citrate, tricalcium-bis-orthophosphate, and additives as desired, and as an essential ingredient, a prolamin (Zein G-200) which is applied to the sodium fluoride during processing of the gum.

Claims

1. In an anticariogenic chewing gum comprising a chewing gum base, sodium fluoride, calcium citrate, tricalcium-bis-orthophosphate and additives, the improvement wherein said sodium fluoride is microcoated by zein G-200.

2. An anticariogenic chewing gum comprising a chewing gum base, sodium fluoride, calcium citrate, tricalcium-bis-orthophosphate, additives, and zein G-200, produced by the process comprising first mixing calcium citrate and tri-calcium-bis-orthophosphate with said base to form a base mixture, enveloping the sodium fluoride with zein G-200 by spraying said zein G-200 on said sodium floride to form a microcoating thereon subjecting said thus coated sodium fluoride to an acid aqueous solution and maintaining it therein for a time sufficient for the acid in said solution to deposit on the outermost layer of said zein, then processing the thus-treated sodium fluoride with an emulsifying agent to form an emulsion, and lastly, incorporating said emulsion into the base mixture by means of a homogenizer.

3. Anticariogenic gum of claim 2 wherein said sodium fluoride is enveloped in from about 0.0004 to 0.001 per cent by weight of zein G-200.

4. Anticariogenic chewing gum of claim 2 or claim 3, wherein the sodium fluoride microcoated by zein G-200 is subjected to an aqueous solution adjusted with citric acid to pH from about 1.5 to 1.8 and maintained therein at a temperature of from about 25°

C. to 30°

C. for a time sufficient for the acid in said solution to deposit on the outermost layer of said zein.
