Is tertiary butylhydroquinone vegan?

Tertiary butylhydroquinone (TBHQ) is a synthetic antioxidant commonly used as a food preservative. It is derived from petroleum and is often added to processed foods such as fast food, snack foods, and baked goods to extend their shelf life. TBHQ is a white crystalline powder that has a slightly bitter taste and a faint odor. It works by slowing down the oxidation process, which helps prevent the development of rancidity and off-flavors in food. While TBHQ has been deemed safe for consumption by regulatory agencies, some studies suggest that it may have adverse health effects in high doses.
