Butylated Hydroxyanisole, also known as tert-butyl-4-hydroxyanisole, butylhydroxyanisole, or BHA for short, is a mixture of two components (3-BHA and 2-BHA).
The molecular formula is C11H16O2, white crystal or crystalline powder, basically odorless, tasteless, and quite stable to heat.
It volatilizes with water vapor when heated. It is insoluble in water, glycerin and propylene glycol, but easily soluble in ethanol (25%) and grease.
The antioxidant effect of butylated hydroxyanisole is achieved by releasing hydrogen atoms to block the auto-oxidation of oils.
BHA (Butylated Hydroxyanisole) and BHT (Dibutyl Hydroxytoluene) are synthetic antioxidants.
BHA (butylated hydroxyanisole), BHT (dibutylated hydroxytoluene), PG (propyl gallate), TBHQ (tert-butyl hydroquinone) and tocopherol are antioxidants widely used internationally .
They can be used alone or in combination with acidic synergists such as citric acid and ascorbic acid to meet the needs of most food products.
BHA and BHT are generally added directly to fats and oils. They can also be added by spraying, such as dissolving antioxidants and spraying them on food.
Used as an antioxidant
The antioxidant effect of Butylated Hydroxyanisole added to food is 1.5-2 times stronger than 2-BHA, but the combination of the two has a certain synergistic effect.
Therefore, a mixture containing a high proportion of 3-BHA is almost as effective as pure 3-BHA.
BHA is mixed with other antioxidants and used in combination with synergist citric acid, etc., and its antioxidant effect is more significant.
Used as an additive
Because Butylated Hydroxyanisole has good thermal stability, it can be used under frying or baking conditions.
It is generally used as a food additive as an antioxidant in oils such as fats, lard, salted fish and shellfish, dried fish and shellfish products, pretzels, fried potato flakes, instant noodles, and fried snacks.
Also used as feed additives and gasoline additives.
Antibacterial and antifungal
In addition to anti-oxidation, BHA also has a strong anti-bacterial power and anti-fungal effect.
Used as a biochemical reagent
3-tert-butyl-4-hydroxyanisole (2-BHA) is also used as a biochemical reagent.
Butyl hydroxyanisole can stabilize the pigment of raw beef as well as prevent the oxidation of ester substances.
BHA can communicate with the peroxide created throughout the oxidation of fats, removed the chain reaction of automated oxidation of fats, as well as avoid the ongoing oxidation of fats.
The use of butylated hydroxyanisole in combination with salt tripolyphosphate and ascorbic acid can postpone the wasting of icy pork chops.
Butyl hydroxyanisole can slightly prolong the life span of spray-dried whole milk powder as well as boost the life span of cheese.
Butyl hydroxyanisole can support the shade of peppers and chili powder, and protect against the oxidation of walnuts, peanuts and other foods.
Including butylated hydroxyanisole right into baking oil and also salt can keep the fragrance of baked goods and also salty peanuts.
Butyl hydroxyanisole can be blended with various other fat-soluble antioxidants, and also its impact is much better.
For example, the combined use of butylated hydroxyanisole as well as dibutylated hydroxytoluene can shield carp, chicken, pork chops as well as frozen smoked pork slices.
The mixture of butylated hydroxyanisole or dibutylated hydroxytoluene, propyl gallate as well as citric acid is added to the butter utilized to make candies to inhibit the oxidation of the sweets.
