Abstract

The chewing gum has an absorbent material, such as polydimethylsiloxane (PDMS), for absorbing or adsorbing volatile and non-volatile chemicals from the user's mouth or breath. While the chewing gum is chewed, chemicals in the user's breath and saliva are absorbed or adsorbed into the absorbent material. The absorbent material is then analyzed to determine the amount of chemicals absorbed or adsorbed into the absorbent material over time. Based on this analysis, various diseases or conditions can be detected or diagnosed.
