Triacetin, also known as glyceryl triacetate, is commonly used as an additive in food products, including chewing gum. It is used as a humidifier and maintains the freshness and elasticity of the gum.
As a flavoring agent, triacetin is not usually used, but it can serve as a solvent for other aromatic compounds. Most of the flavors in gum are essential oils, complex chemical compounds with a high concentration of flavors and odors. For example, menthol is added for mint flavor, and other essential oils can give fruit flavors.
Nevertheless, it is worth emphasizing that the use of any kind of additives in food must strictly comply with regulatory standards and requirements of the relevant territory or country. In some countries, for example, the use of certain types of supplements may be restricted or prohibited.
