Key Application
1. Food Industry: High-Efficiency Antioxidant for Oils & Fats
BHT (Butylated Hydroxytoluene) is a classic additive used to prevent oxidative rancidity of edible oils and fats. It boasts wide-ranging applications:
Edible Oils & Fats: Prevents oxidative deterioration of vegetable and animal fats. Recommended dosage: 0.1 - 0.2 g/kg (calculated by fat content).
Fried Foods: Maintains freshness of instant noodles, potato chips, fried nuts, etc., by preventing oxidation.
Baked Goods: Prevents rancidity of fats in biscuits, pastries, mooncakes, and other baked products.
Meat Products: Extends shelf life of preserved pork, sausages, and salted meat products by protecting oil components.
Chewing Gum Base: Preserves stability in chewing gum formulations.
Regulatory Compliance: According to GB 2760, the maximum usage limit of BHT in foods is 0.2 g/kg (calculated by fat content).
2. Feed Industry
Animal Feed: Prevents oxidation in animal feed, preserving freshness and nutritional value.
Pet Food: Extends shelf life of pet food and prevents rancidity.
Aquafeed: Protects highly unsaturated fatty acids (e.g., fish oil) in aquafeed formulations.
3. Cosmetics & Personal Care
Oil-Based Cosmetics: Added to lipsticks, lip balms, facial creams, and body oils to prevent oxidative rancidity of components.
Fragrance Stabilization: Stabilizes fragrance ingredients and prevents oxidative deterioration of essential oils and aromatic compounds.
4. Industrial Applications
Rubber & Plastics: Acts as an antioxidant to prevent polymer material aging and brittleness.
Biodiesel: Enhances the oxidative stability of biodiesel, extending its service life.
Lubricants: Improves the oxidation resistance of lubricating oils, prolonging their operational lifespan.
Packaging Materials: Utilized in food packaging materials to exert antioxidant effects through migration.
FAQ: BHT
1. What is BHT (Butylated Hydroxytoluene)?
BHT, or Butylated Hydroxytoluene (CAS 128-37-0), is a highly efficient and stable oil-soluble synthetic antioxidant. It appears as a white crystalline powder, widely used to prevent oxidative rancidity and extend shelf life in foods, feeds, cosmetics, and industrial products.
2. What are the core benefits of BHT?
Superior Antioxidation: Effectively inhibits oxidation of animal and vegetable oils, significantly extending the induction period of fats.
Thermal Stability: Resists degradation under high heat, making it suitable for frying and baking processes.
Synergy: Produces a strong synergistic effect when combined with BHA, TBHQ, or citric acid, boosting overall antioxidant performance.
3. In which industries is BHT commonly used?
BHT is a versatile additive across multiple sectors:
Food Industry: Edible oils, fried foods, baked goods, meat products, and chewing gum.
Feed Industry: Animal feed, pet food, and aquafeed to preserve fat content.
Cosmetics: Lipsticks, creams, and fragrances to prevent oil oxidation.
Industrial: Rubber/plastics, biodiesel, lubricants, and food packaging materials.
4. What are the global regulatory standards for BHT?
BHT is widely approved internationally:
China: Compliant with GB 2760, maximum dosage 0.2 g/kg.
USA: FDA classified as GRAS (Generally Recognized As Safe).
EU: Approved under EU food additive regulations.
JECFA: Established an ADI (Acceptable Daily Intake) of 0-0.3 mg/kg body weight.
5. How is BHT applied in food production?
BHT offers flexible application methods to suit different processes:
Direct Addition: Simply mix into oils or fats.
