ENCAPSULATED ACID, ITS PRODUCTION AND CHEWING GUM COMPOSITION CONTAINING SUCH ACID Russian patent published in 2015 - IPC A23G4/00 

FIELD: food industry.

SUBSTANCE: present invention relates to food industry. The method involves melt blending of 30 - 90 wt % of poly(vynylacetate) having mean molecular weight equal to 80000 - 300000 atomic weight units, 5 - 20 wt % of a fatty acid salt and 5 - 50 wt % of a food acid. All wt % values are derived from the total weight of the encapsulated food acid. The fatty acid salt is selected from among the sodium salt of C₁₂-C₃₆ of aliphatic carboxylic acid, the potassium salt of C₁₂-C₃₆ aliphatic carboxylic acid, the calcium salt of C₁₂-C₃₆ of aliphatic carboxylic acid, the zinc salt of C₁₂-C₃₆ of aliphatic carboxylic acid, the magnesium salt of C₁₂-C₃₆ of aliphatic carboxylic acid, the aluminium salt of C₁₂-C₃₆ of aliphatic carboxylic acid or their combinations. The food acid is chosen from among adipic acid, ascorbic acid, aspartic acid, benzoic acid, citric acid, fumaric acid, gluconic acid, maleic acid, malic acid, oxalic acid, phosphoric acid, sorbic acid, amber acid, tartaric acid and their mixtures. As a result of blending, encapsulated food acid is obtained. Then one performs melt blending of a chewing base, a sweetener and the encapsulated food acid to produce a chewing gum composition.

EFFECT: introduction of a food acid encapsulated with poly(vynylacetate) and a fatty acid salt ensures more prolonged release of a sour taste and aroma as compared to a food acid encapsulated with solely poly(vynylacetate).
