System and method for detection of a contaminated beverage

A method for producing an apparatus configured to detect a beverage that is contaminated with a substance, comprising:

• creating a testing material that comprises a molecularly imprinted polymer with a cavity having a complementary shape to a molecule associated with the substance;
• and
• filling the cavity with a template molecule, wherein the template molecule is attached to a taste substance, the taste substance having a distinct taste, wherein the beverage has a first taste, wherein the taste substance attached to the template molecule filling the cavity bleeds out into the beverage when the molecule associated with the substance in the beverage replaces the template molecule filling the cavity, wherein the first taste of the beverage changes to a second taste to include the distinct taste of the taste substance when the template molecule attached to the taste substance bleeds out into the beverage as an indicator that the substance is present in the beverage, wherein the taste substance attached to the template molecule is food grade.
