Applications of Talc in Chewing Gum

Purified Talc, or Food Grade Talc, possesses several innate physical and mechanical properties which are congenial for use in Chewing Gum manufacturing:

  • Since Talc is organophilic in nature, it combines extremely well with polymers derived from natural or synthetic resins. Therefore, it is a critical filler which provides bulk and texture to chewing gum bases.
  • As compared to other fillers, Food Grade Talc gives no reaction with the acidic flavours/ingredients and no Carbon Dioxide is released.
  • Food Grade Talc ranks high in whiteness and brightness. Thus, it elevates the brightness of colours in food dyes while keeping them safe for human consumption.
  • Food Grade Talc has a smooth and lamellar (platy and layered) structure. Consequently, when applied to the outer surface of gum candies, it provides a shiny polish. Additionally, it prevents stickiness and formation of lumps.
