Butylated Hydroxytoluene (BHT)
CAS No.: 128-37-0
Butylated Hydroxytoluene, abbreviated as BHT, is a synthetic phenolic antioxidant with mature and stable properties, which has become an indispensable preservation additive throughout the global food manufacturing industry.
Its core functional advantage lies in outstanding oxidation resistance targeting grease systems. When added to edible oils and all types of high-fat food products, it can effectively block the chain reaction of lipid oxidation, slow down rancidity, avoid unpleasant off-flavors and quality deterioration caused by oxidation, well retain the original taste, color and nutritional characteristics of food, and greatly extend the overall shelf life of finished food.
From a safety perspective, BHT carries a low-toxicity toxicological profile after long-term comprehensive safety evaluation and repeated verification. It gains wide recognition and official approval for addition in daily consumer commodities. Thanks to its excellent material compatibility, it can be flexibly formulated into a great many food-related consumer goods. Given its extensive application scenarios, the general population may have regular contact with this ingredient, and relevant safety assessment data fully proves that conventional daily exposure will not bring hidden risks to human health.
