Butyl Hydroxyanisole (BHA) is a commonly used food antioxidant with multiple properties and wide applications.
Basic information
Butyl hydroxyanisole, also known as tert-butyl-4-hydroxyanisole, has a chemical formula of C11H1602 and a molecular weight of 180.25. It has two isomers: 3-BHA and 2-BHA, usually a mixture of the two
Butyl hydroxyanisole is a white to light yellow waxy solid with a slight peculiar odor, a melting point of 48-63°C, a boiling point of 264-270°C (98KPa), insoluble in water, and easily soluble in ethanol, propylene glycol and various oils
Chemical properties
Butyl hydroxyanisole is heat-stable and is not easily destroyed under weakly alkaline conditions. Long-term exposure to light will cause the color to darken. The antioxidant effect of 3-BHA is 1.5 to 2 times stronger than that of 2-BHA, and the two can be mixed to enhance the effect
In addition, butylated hydroxyanisole has a certain volatility and can be distilled by steam, so it is easy to lose in high-temperature products
Application areas
Food industry: Butylated hydroxyanisole is widely used in oily foods and fat-rich foods, such as baked foods, cereal foods, candies, chewing gum, etc. It can prevent the oxidation of fats and oils in foods, maintain the freshness and flavor of foods, and extend the shelf life of foods
Feed industry: Butylated hydroxyanisole is also used in animal feed as an antioxidant to protect the nutrients in the feed from being destroyed by oxidation
Other industries: In addition, butylated hydroxyanisole can also be used for antioxidant treatment of food packaging materials
