Abstract
The present invention comprises the encapsulation of the artificial sweetener L-aspartyl-L-phenylalanine methyl ester (APM) within a coating material including cellulose ethers, cellulose esters, certain vinyl polymers, gelatin and zein, in a ratio of coating material to APM to 1:1 or less. Shelf stability of products containing the encapsulated APM is nearly doubled. The presently stabilized APM is particularly suited for incorporation into chewing gum formulations.
Claims35
L-aspartyl-L-phenylalanine methyl ester comprising solid particles of said methyl ester encapsulated by a coating material selected from the group consisting of cellulose, cellulose derivatives, arabinogalactin, gum arabic, polyolefins, waxes, vinyl polymers, gelatin, zein and mixtures thereof, wherein the amount of said coating material to said methyl ester is from 1:1 to 1:10.
A method for preparing L-aspartyl-L-phenylalanine methyl ester having improved shelf stability when incorporated in food products, comprising forming solid particles of said methyl ester, and
- encapsulating said solid particles in a coating material selected from the group consisting of cellulose, cellulose derivatives, arabinogalactin, gum arabic, polyolefins, waxes, vinyl polymers, gelatin, zein and mixtures thereof, wherein the amount of said coating material to said methyl ester is from 1:1 to 1:10 wherein said methyl ester is encapsulated by the deposition of the coating material at a temperature of up to about 200.degree. F.
A method for extending the shelf stability of a chewing gum composition to which the sweetener L-aspartyl-L-phenylalanine methyl ester is to be added, comprising forming solid particles of said methyl ester, and
- encapsulating said solid particles in a coating material selected from the group consisting of cellulose, cellulose derivatives, arabinogalactin, gum arabic, polyolefins, waxes, vinyl polymers, gelatin, zein and mixtures thereof, wherein the amount of said coating material to said methyl ester is from 1:1 to 1:10, and
- recovering the encapsulated particles, and incorporating said encapsulated particles into said chewing gum composition.
