Chewing gum composition comprising encapsulated acid

A chewing gum composition comprising:

• a gum base, a sweetener, and
• an encapsulated food-grade acid comprising, based on the weight of the encapsulated food-grade acid,
• about 30 to about 90 weight percent of a poly(vinyl acetate), wherein the poly(vinyl acetate) has a weight average molecular weight from 80,000 to about 300,000 atomic mass units;
• about 5 to about 20 weight percent of a fatty acid salt, wherein the fatty acid salt is selected from the group consisting of a sodium salt of a C12-C36 aliphatic carboxylic acid, a potassium salt of a C12-C36 aliphatic carboxylic acid, a calcium salt of a C12-C36 aliphatic carboxylic acid, a zinc salt of a C12-C36 aliphatic carboxylic acid, a magnesium salt of a C12-C36 aliphatic carboxylic acid, an aluminum salt of a C12-C36 aliphatic carboxylic acid, and combinations thereof;
• and about 5 to about 50 weight percent of a food-grade acid, wherein the food-grade acid is selected from the group consisting of adipic acid, ascorbic acid, aspartic acid, benzoic acid, citric acid, fumaric acid, glutamic acid, maleic acid, malic acid, oxalic acid, phosphoric acid, sorbic acid, succinic acid, tartaric acid, and mixtures thereof;
• wherein the chewing gum composition further comprises the unencapsulated food-grade acid in an amount from 0.1 to 2.0 weight percent of the total weight of the chewing gum composition.
