Question

Sodium benzoate is used for

• A. Value addition
• B. Preservation
• C. Fortification
• D. Control of diseases

Hint:

Remember the common class II chemical preservatives used in food processing: Sodium benzoate (for acidic foods), Potassium metabisulphite (KMS) (for juices, prevents browning), and Sorbic acid (against yeast and mold).

Answer 1

The Correct Option is B

Step 1: Identify the Purpose:
The question concerns the main function of sodium benzoate in food.

Step 2: Explanation:
Sodium benzoate, a salt of benzoic acid, is a common food preservative. It functions by preventing the growth of microorganisms, including yeast, mold, and some bacteria. Its effectiveness peaks in acidic environments (pH $<$ 4.5), making it ideal for preserving acidic foods and drinks like fruit juices, jams, pickles, and carbonated beverages.
\[\begin{array}{rl} \bullet & \text{Value addition focuses on increasing a product's economic worth, a broader concept. } \\ \bullet & \text{Fortification involves adding micronutrients (vitamins and minerals) to food. } \\ \bullet & \text{Disease control usually pertains to managing plant or human diseases, not the primary role of sodium benzoate as a food additive. } \\ \end{array}\] Thus, its main role is preservation.

Step 3: Conclusion:
Sodium benzoate is used to preserve food products.
