Which synthetic aromatic organic compound inhibits the chemical breakdown of food that occurs in the presence of oxygen, commonly used in foods such as crackers, microwave popcorn, butter and chicken nuggets?
Tertiary butyl hydroquinone
The correct answer is Option 1: Tertiary butyl hydroquinone (commonly abbreviated as TBHQ).
Explanation
Tertiary butyl hydroquinone (TBHQ) is a synthetic aromatic organic compound that functions as an antioxidant.
How it works: It prevents oxidation by reacting with free radicals, which effectively inhibits the chemical breakdown of fats and oils in food when exposed to oxygen. This prevents rancidity, preserves the food's flavor, and extends its shelf life.
Common uses: Because of its high stability at high temperatures, it is widely used in processed and fried foods like crackers, microwave popcorn, butter, vegetable oils, and chicken nuggets.
Why the other options are incorrect:
Option 2: Diethyltoluamide (DEET) DEET is a synthetic organic chemical widely used as the active ingredient in insect repellents. It is not used in food.
Option 3: Sodium hypochlorite This is the active chemical compound in household bleach and is used as a disinfectant or water purifier. It is highly toxic if ingested.
Option 4: 1,4-dichlorobenzene This is an aromatic organic compound used primarily as a fumigant and disinfectant, famously found in mothballs and restroom deodorant blocks. It is not a food additive.
