Question

Nitrates are used in meats as -

• A. Curing agents
• B. Emulsifier
• C. Anti-caking agents
• D. Bleaching agent

Hint:

To minimize potential health risks associated with the formation of carcinogenic nitrosamines during high-temperature cooking, regulatory agencies (like FSSAI/FDA) strictly limit the maximum permissible residual levels of nitrites and nitrates in cured meats.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Meat curing is a traditional preservation process that involves adding salt, sugar, and nitrites/nitrates to meat to improve shelf-life, safety, color, and flavor.

Step 2: Detailed Explanation:
Sodium or potassium nitrates (and nitrites) are essential curing agents in processed meats (such as bacon, ham, and sausages).
They serve multiple critical roles:
- Antimicrobial preservation: Specifically inhibiting the germination of Clostridium botulinum spores.
- Color development: Nitrites break down into nitric oxide (\(\text{NO}\)), which binds to myoglobin to form nitrosomyoglobin, converting upon heating to the stable pink pigment nitrosylhemochrome.
- Flavor development: Contributing to the characteristic cured meat aroma and preventing lipid oxidation (warmed-over flavor).

Step 3: Final Answer:
Therefore, nitrates are used in meats as curing agents, which corresponds to option (A).
