Which of the following chemicals is commonly used for preserving tomato sauces?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Sodium benzoate.
Tomato sauces are commonly preserved using sodium benzoate (E211) or citric acid (E330). Sodium benzoate inhibits mold and bacterial growth in acidic foods like tomato sauce, while citric acid enhances acidity, preventing spoilage and maintaining flavor. Vinegar and salt can be used for a more natural approach, but may alter the taste. Proper pasteurization and airtight packaging also contribute to shelf life.
