  • Publication number: 20160213024
    Abstract: A method for producing chewing-gum compositions containing xylitol introduced in the form of a powder as polyol, by introducing into the compositions at least one anti-caking agent, preferably having a specific surface BET of at least 200 m2/g. The hardness of the chewing-gum thus obtained is increased, such an increase being desirable, for example, for preventing the deformation of centers to be sugar-coated in the sugar-coating turbines or improving the stick-packaging rates. The anti-caking agent is previously mixed with the powdery xylitol, and the mixture may be provided in the form of a powdery composition of xylitol and the anti-caking agent.

  • Publication number: 20160213023
    Abstract: A method for producing a chewing-gum composition containing a powdery composition of maltitol, by introducing into the composition at least one anti-caking agent, preferably having a specific surface BET of at least 200 m2/g. The hardness of the chewing-gum thus obtained is increased, such an increase being desirable, for example, for preventing the deformation of centers to be sugar-coated in the sugar-coating turbines or improving the stick-packaging rates. The anti-caking agent is either introduced as a direct additive into the chewing-gum in like manner as the powdery maltitol composition, or as part of a mixture of the anti-caking agent and the powdery maltitol composition.

  • Patent number: 9220684
    Abstract: A pulverulent crystalline maltitol composition, is characterized in that it has a laser volume mean diameter between 10 and 150 ?m; in that it has a maltitol content between 80 and 99.9% by weight; in that at least 50% by weight of its particles flow through a sieve having a cut-off threshold of 2000 ?m according to a test A1; in that at least 35% by weight of its particles flow through a sieve having a cut-off threshold of 2000 ?m according to a test A2; and in that it includes from 0.1 to 20% by weight of at least one water-insoluble anti-caking agent, the anti-caking agent having a hygroscopicity, determined according to the test B, between 2.5 and 25%. This composition is not subject to caking, and finds applications in the food and pharmaceutical fields.

  • Publication number: 20150313255
    Abstract: A method of using at least one anti-caking agent, preferably one with a specific surface area BET of at least 20 m2/g for manufacturing chewing gum compositions including at least sorbitol in powdered form as a sweetener. The hardness of chewing gums obtained from these compositions is increased, such an increase being desirable, for example to avoid deforming the centres to be coated in the coating turbines or to improve stick packaging speeds. The anti-caking agent is either introduced as an additive directly into the chewing gum, or mixed with the powdered sorbitol beforehand.
