Tertiary Butylhydroquinone (TBHQ), with the CAS number 1948-33-0, is a synthetic antioxidant and preservative commonly used in the food industry1. It is effective in small quantities and is known for its ability to extend the shelf life of oils and fats by preventing oxidative rancidity2. TBHQ is a white or off-white crystalline solid that is soluble in most organic solvents and oils, but only slightly soluble in water2.
This antioxidant is used in a variety of food products, including fried snacks, baked goods, and coatings on fruits and vegetables to maintain freshness and flavor. It is also used in cosmetics and pharmaceutical products for its preservative properties2.
TBHQ is recognized as a safe food additive by many regulatory agencies, including the U.S. Food and Drug Administration (FDA), although it is used at levels significantly lower than those found to be harmful in animal studies. The FDA has set a limit of 0.02% of the oil or fat content in food products for TBHQ usage2.
It is worth noting that TBHQ has been the subject of safety concerns due to its structural similarity to butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT), which are also synthetic antioxidants. However, extensive research has shown that TBHQ does not pose a significant risk to human health when used at approved levels.
