### Step-by-Step Solution:

1. **Identify the Compound**: The question asks about butylated hydroxy toluene (BHT) as a food additive.

2. **Understand the Structure**: BHT is derived from toluene, which has a benzene ring with a hydroxy group and butyl groups attached. The structure includes a benzene ring, a hydroxyl (-OH) group, and butyl groups.

3. **Function of BHT**: BHT is known for its properties as an antioxidant. Antioxidants are substances that prevent oxidation, which is a chemical reaction that can produce free radicals leading to chain reactions that may damage cells.

4. **Role in Food Preservation**: In the context of food, BHT helps prevent the oxidation of fats and oils, which can lead to rancidity. Rancidity affects the taste, smell, and nutritional value of food.

5. **Conclusion**: Therefore, butylated hydroxy toluene acts as an antioxidant when used as a food additive, helping to maintain the quality of food products.
