Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks for the International Numbering System (INS) code for Monosodium Glutamate (MSG). The INS is a European-based naming convention for food additives, similar to E-numbers.

Step 2: Detailed Explanation:

• The 600 Series: In the INS system, numbers in the 600-699 range are reserved for Flavor Enhancers.

• Glutamates: The first few numbers in this range are allocated to glutamic acid and its salts:
- INS 620: Glutamic acid.
- INS 621: Monosodium glutamate (MSG).
- INS 622: Monopotassium glutamate.
- INS 623: Calcium diglutamate.

• Function of MSG: It is the sodium salt of a naturally occurring non-essential amino acid. It enhances the "Umami" (savory) taste by stimulating specific receptors on the tongue. It is widely used in soups, snacks, and Asian cuisine.

Step 3: Final Answer:
The INS number for Monosodium glutamate is 6
