Sodium Nitrite 99% Powder,Food grade

CAS:7632-00-0,

Sodium nitrite is primarily used as a food preservative and color fixative in processed meats, such as bacon, ham, and sausages. It helps inhibit the growth of harmful bacteria, particularly Clostridium botulinum, and enhances the reddish-pink color of cured meats. Beyond food applications, sodium nitrite is used in the production of dyes and as a reagent in various chemical processes. In medicine, it serves as an antidote for cyanide poisoning. However, its use is regulated due to potential health risks when consumed in large quantities.

Sodium nitrite (NaNO₂) is a versatile chemical compound used in various industries, primarily for its preservative, coloring, and antimicrobial properties. Here are some of its common applications:

### 1. **Food Industry**
   - **Preservative in Processed Meats**: Sodium nitrite is commonly used to cure meats like bacon, ham, and sausages. It helps preserve the color, flavor, and prevents the growth of harmful bacteria, especially *Clostridium botulinum*, which causes botulism.
   - **Color Fixative**: It maintains the pinkish-red color in cured meats by interacting with myoglobin in the muscle tissue.

### 2. **Pharmaceuticals**
   - **Antidote for Cyanide Poisoning**: Sodium nitrite is part of the cyanide antidote kit. It converts hemoglobin to methemoglobin, which binds to cyanide, neutralizing its toxic effects.
   - **Vasodilator**: In some cases, sodium nitrite is used to widen blood vessels (vasodilation) for treating certain medical conditions.

### 3. **Chemical Industry**
   - **Manufacturing Dyes**: Sodium nitrite is used in the synthesis of azo dyes, which are widely used in textiles, printing, and leather industries.
   - **Rubber Industry**: It's used as an inhibitor to prevent rubber degradation during processing.

### 4. **Metallurgy**
   - **Corrosion Inhibitor**: Sodium nitrite is used as a corrosion inhibitor in various metalworking processes. It's commonly added to cooling systems, where it prevents rusting of metals.
  
### 5. **Environmental Applications**
   - **Wastewater Treatment**: Sodium nitrite is used in some wastewater treatment processes to control odors and prevent the formation of hydrogen sulfide gas.

### 6. **Laboratory Use**
   - **Chemical Reagent**: It is used as a reagent in various chemical reactions, particularly in diazotization reactions in organic chemistry.

Despite its benefits, sodium nitrite must be used with caution due to its toxicity in high amounts, and strict limits are set for its use, particularly in the food industry.
