INTRODUCTION

Denatonium is one of the most bitter chemical compounds known and is usually available as  Denatonium Benzoate [DB] and Denatonium Saccharide with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide. They are used as aversive agents (bitterants) to prevent inappropriate ingestion.

The repulsive taste of denatonium can be used as a deterrent on products not designed for consumption and/or are harmful upon consumption.
