What Sodium Glutamate(MSG) Is
Introduction: Sodium Glutamate(MSG) is a white prismatic crystals or crystalline powder, odorless, with a unique meaty flavor, easily soluble in water. It’s an organic compound, and the sodium salt of glutamic acid. The main component of MSG, a commonly used seasoning in daily life, is sodium glutamate. Widely used in households, catering industry, and food processing industry. It is also commonly used as medical and biochemical reagents.
Synonyms: Sodium 5-oxido-5-oxonorvaline; Monosodium glutamate with other flavour-enhancers; DL-monosodium glutamate; sodium glutamate(1-); α-Amiopetandioic acid monosodium salt; sodium acid l-glutamate; Monosodium glutamate; Glutamic acid, monosodium salt, DL-
Chemical Properties: Stable to light and heat, does not absorb moisture. It has a molar mass of 169.11109 g/mol and a 1.635 g/cm³ density. In an acidic environment, sodium glutamate will produce glutamic acid or glutamate hydrochloride; in an alkaline environment, sodium glutamate will react chemically to produce a substance called disodium glutamate.
Reactivity and Uses: Sodium glutamate is the most widely used umami agent at home and abroad. When coexisting with salt, it can enhance its taste-presenting effect. Our country stipulates that it can be used in appropriate amounts in various types of food according to production needs.

Production Technology of Sodium Glutamate(MSG)
1. Raw Material Preparation
A. Source Materials:
- Carbohydrates: Common sources include starch, molasses, or sugar cane.
- Nitrogen Source: Ammonium salts, urea, or other nitrogenous compounds.
2. Fermentation
A. Microorganisms:
- Select strains of Corynebacterium glutamicum or Brevibacterium flavum are used to produce glutamic acid through fermentation.
B. Fermentation Conditions:
- Temperature: Typically maintained between 30-35°C.
- pH: Controlled at around 7.0 using ammonia or other pH regulators.
- Aeration: Adequate oxygen supply is essential for optimal microbial growth and glutamic acid production.
- Duration: The fermentation process generally takes 2-3 days.
3. Extraction and Purification
A. Separation of Biomass:
- After fermentation, the microbial cells are separated from the fermentation broth using centrifugation or filtration.
B. Crystallization:
- The glutamic acid in the broth is converted to its sodium salt by neutralizing with sodium hydroxide, resulting in MSG.
C. Purification:
- The MSG is then crystallized out of the solution by adjusting the temperature and pH. The crystals are separated, washed, and dried.
4. Refining
A. Recrystallization:
- The crude MSG crystals undergo further purification through recrystallization to achieve high purity. This involves dissolving the crude crystals in water, filtering, and recrystallizing the product.
B. Drying:
- The purified MSG crystals are dried to remove any residual moisture.
C. Milling:
- The dried crystals are milled to the desired particle size.
5. Quality Control
A. Testing:
- The final product undergoes rigorous quality control testing to ensure it meets the required standards for purity, composition, and safety.
B. Packaging:
- The MSG is packaged in suitable containers to protect it from moisture and contamination during storage and transportation.
6. Environmental Considerations
A. Waste Management:
- Proper treatment and disposal of fermentation by-products and waste materials are crucial to minimize environmental impact.
B. Energy Efficiency:
- Optimizing energy use throughout the production process to reduce costs and environmental footprint.

Environment and Health
Environmental Impact
The production of MSG typically involves the fermentation of carbohydrates like sugarcane or corn starch. This process can have several environmental implications:
- Water Consumption: The fermentation process requires significant amounts of water, leading to concerns about water resource depletion.
- Energy Use: Large-scale fermentation and purification processes consume considerable energy, contributing to carbon emissions.
- Waste Generation: The production process generates by-products and waste materials, which need to be managed properly to avoid environmental contamination.
Storage and transportation
- Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep container tightly sealed. They should be stored separately from acidic substances, strong oxidants, and flammable substances, and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.
- Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety glasses, anti-toxic substance penetration overalls, and rubber gloves. Avoid dust generation. Avoid contact with acids, strong oxidants, and flammable materials. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment.
Health Implications
- It is generally harmless if inhaled, absorbed or absorbed through the skin. Excessive heating will produce sodium pyroglutamate, which may have certain effects on human health.
- Eye contact: Lift eyelids and rinse with running water or saline. Seek medical attention.
Regulatory Compliance
- MSG is recognized as safe for consumption by numerous health authorities, including the U.S. Food and Drug Administration (FDA) and the World Health Organization (WHO). However, it is regulated to ensure purity and safety for consumers.
Sodium Glutamate(MSG) FAQs
Monosodium glutamate (MSG) is the sodium salt of the common amino acid glutamic acid. Glutamic acid is naturally present in our bodies, and in many foods and food additives.
FDA considers the addition of MSG to foods to be “generally recognized as safe” (GRAS). Although many people identify themselves as sensitive to MSG, in studies with such individuals given MSG or a placebo, scientists have not been able to consistently trigger reactions.
The glutamate in MSG is chemically indistinguishable from glutamate present in food proteins. Our bodies ultimately metabolize both sources of glutamate in the same way. An average adult consumes approximately 13 grams of glutamate each day from the protein in food, while intake of added MSG is estimates at around 0.55 grams per day.
