The foods we consume can have different kinds of compounds in them that we didn’t know about. These compounds added to the foods we eat are not always detectable. For instance certain compounds can be listed on the nutrition label and we can’t even taste or see them. Butylated hydroxyanisole and butylated hydroxytoluene, also known as BHA and BHT, are both phenolic compounds that are added to certain foods in order to preserve fats and oils. Even though these compounds are used to preserve the foods we eat, how do we know that BHA and BHT aren’t bad for us? Even though BHA and BHT have minimal negative effects, they are outweighed by many beneficial attributes and are not bad for us. Knowing what these compounds are made of, what their functions are, and how they work will help in answering this central question.
Even though BHA and BHT both have the same function, they have different characteristics. “BHA is a mixture of the isomers 3-tert-butyl-4-hydroxyanisole and 2-tert-butyl-4-hydroxyanisole, also known as BOA.” The molecular formula of BHA is C11H16O2. BHA can be a yellow tainted or white waxy solid and can have an aromatic odor. BHT “also known as 3, 5-di-tert-butyl-4-hydroxytoluene; methyl-di-tert-butylphenol; 2, 6-di-tert-butyl-para-cresol,” has a molecular formula of C15H240. BHT physically looks like a white powder. Even though BHA and BHT are used for the same things, BHA is more stable at higher temperatures than BHT so it is used more. There are other antioxidants that can be used like NDGA but they are more expensive than BHA and BHT. BHA and BHT can be found in certain foods or can be found in certain food packaging. BHA and BHT do not have to be directly put into food and products to work. They can be placed in the packaging of food and will have the same effect. These compounds have not only been used to preserve food, but animal feed and some cosmetic
