TERT-BUTYLHYDROQUINONE'S FUNCTION in FOOD:
Tert-Butylhydroquinone is a common antioxidant that prevents fat oxidation. 
Oxidation can cause the foods to lose flavor, change color and deplete their nutritional value. 
Since oxidation can lead to fats turning rancid, Tert-Butylhydroquinone can also help increase shelf life and reduce the amount of food waste from food spoilage. 

You’ll often find Tert-Butylhydroquinone in foods like crackers, fats and oils, chips, donuts, some breads, popcorn, other snacks, pre-made frozen foods and packaged dinners. 
The U.S. Food and Drug Administration (FDA) classified Tert-Butylhydroquinone as Generally Recognized as Safe, or “GRAS,” and approved Tert-Butylhydroquinone's use in foods in 1972. 
This decision came as pre–made foods were becoming increasingly popular. 

Today, many people rely on pre–made foods in some way over the course of their day, and food manufacturers use preservatives like Tert-Butylhydroquinone to keep foods from going bad as they are transported and stored in freezers, refrigerators, and on store and household shelves. 
Stored fats and oils, along with foods that contain these ingredients, can become moldy, stale or simply unappetizing over time, and Tert-Butylhydroquinone's antioxidant properties help preserve those fats and oils by eliminating their oxygen content.  

WHY TERT-BUTYLHYDROQUINONE SAFE?
A 2004 European Food Safety Authority (EFSA) 2004 Panel found that Tert-Butylhydroquinone is not carcinogenic. 
Tert-Butylhydroquinone has been approved by leading regulatory and health organizations around the world such as EFSA, the U.S. Food and Drug Administration (FDA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA).
