TBHQ (tert-butylhydroquinone) is a synthetic phenolic antioxidant widely used to prevent oils, fats, and fried foods from going rancid. Known as E319 with CAS 1948-33-0, it is one of the most effective antioxidants for extending shelf life and maintaining food quality.

What Is TBHQ?

TBHQ is a food-grade antioxidant approved by the FDA in 1972. It works by scavenging free radicals and interrupting lipid oxidation. Compared with BHA and BHT, TBHQ often delivers stronger antioxidant activity and better thermal stability—making it ideal for high-temperature applications like frying.

Key Benefits of TBHQ

• Excellent oxidative stability for edible oils and fats

• High carry-through protection in fried foods

• Effective at low usage levels

• Good thermal stability during processing

• Cost-effective preservation for packaged foods

Common Applications

TBHQ is used in:

• Edible oils and fats

• Potato chips, crackers, and snacks

• Instant noodles

• Baked goods

• Fried foods

• Cured meat and dried fish products

• Pharmaceuticals, cosmetics, and biodiesel

Safety and Regulatory Status

TBHQ is approved in the U.S., EU, and many other regions. The EU permits TBHQ at 200 mg/kg, while Codex Alimentarius sets limits up to 200 mg/kg for edible oils and fat-based foods. The JECFA ADI is 0.7 mg/kg body weight per day. When used within regulatory limits, TBHQ is considered safe for general consumption.

Market Outlook

Global demand for TBHQ remains steady, driven by processed food growth and the need for reliable antioxidants. Asia Pacific is a key growth region, while North America maintains strong demand. Clean-label trends are increasing interest in natural alternatives, but TBHQ remains a proven, cost-effective solution.
