Which chemical compound is commonly utilised as a preservative in tomato sauce?
Show answer & explanation
Correct answer: D
Explanation
The Correct Answer is option 4 i.e. Sodium Benzoate.
Sodium Benzoate is the most commonly used preservative in products like tomato sauce, fruit juices, and soft drinks. It is effective in preventing the growth of bacteria, yeast, and fungi, thereby extending shelf life. It works best in acidic environments, which makes it ideal for tomato-based products. The compound is generally recognized as safe when used in permissible limits. Its ability to inhibit microbial growth without altering the taste significantly makes it a preferred choice in the food industry for long-term storage and distribution of condiments like ketchup and sauces.
Other options :
-
Carnosic Acid: A natural antioxidant found in rosemary, used in fats and oils, not common in sauces.
-
Green Tea Extract: Used for its antioxidant properties, not primarily as a preservative.
-
Vinegar: Acts as a mild preservative due to its acidity but is not as effective or standardized as sodium benzoate.
