Monosodium Glutamate/MSG CAS: 142-47-2

Food-grade monosodium glutamate (MSG, CAS 142-47-2) is the sodium salt of L-glutamic acid, a naturally occurring amino acid found in protein-rich foods such as tomatoes, cheese, mushrooms, and seaweed. It is one of the most widely used flavor enhancers in the global food industry, prized for its ability to deliver and intensify the savory umami taste.

Commercial MSG is produced through microbial fermentation using corn or starch as raw material. This process - fermentation → glutamic acid extraction → neutralization → crystallization → drying → screening - converts carbohydrates into high-purity L-glutamic acid using food-grade bacterial strains. This method accounts for over 90% of global MSG production and is recognized as safe by FDA, EFSA, and JECFA.

Our MSG meets ≥99.0% purity (dry basis) and is available in a range of particle sizes: 30, 40, 50, 60, 80 and 100 mesh. Finer mesh dissolves faster for liquid applications, while coarser crystals are preferred in dry blends where visible dispersion matters.

The bulk MSG products Sinoright supplied are produced in internationally certified manufacturers including Fufeng, Meihua, and Lianhua. Our product complies with GB/T 8967, FCC 12th Edition, and JECFA standards. Full COA and supporting documentation are provided with each shipment.

Test Standard: GB/T 8967 (National food safety standard for MSG, China)

Seasonings & Compound Blends

MSG enhances umami and rounds out salty and savory notes in compound seasonings, barbecue rubs, hot pot soup bases, instant noodle seasonings, snack flavorings, bouillon cubes, and table salt blends. It works synergistically with other flavor enhancers to create a fuller, more balanced taste profile.

Processed Foods

In industrial food production, MSG helps maintain consistent flavor across batches in canned foods, frozen meals, soups, sauces, ready-to-eat products, and processed meat and poultry items. It supports formulation stability and enables sodium reduction by partially replacing salt without sacrificing taste.

Fermented Condiments

In soy sauce, vinegar, oyster sauce, and fermented bean products, MSG deepens the umami profile and contributes to a rounder, more complex flavor. It is commonly applied during aging or finishing stages to standardize taste quality across production runs.

Other Applications

MSG is also used in microbial culture media as a nitrogen source for fermentation-based manufacturing, and as a feed attractant in aquaculture. These represent a niche but established segment of MSG applications.

Q1: What is the correct CAS number for food-grade MSG? I've seen 142-47-2, 6106-04-3, and 32221-81-1.

The CAS number used in our product documentation is 142-47-2, which corresponds to monosodium glutamate (anhydrous basis). This is the CAS referenced in international food standards including FCC (Food Chemicals Codex), JECFA, and GB/T 8967, and is widely accepted for customs declarations and regulatory filings worldwide. CAS 6106-04-3 refers to the monohydrate crystalline form in certain chemical registries, and CAS 32221-81-1 is not commonly used in international food-grade MSG trade or food additive specifications. Accordingly, our product documentation and commercial quotations use CAS 142-47-2 as the primary reference.

Q2: How do you guarantee the quality of food-grade MSG? Do you provide a COA?

Yes. Each batch is accompanied by a detailed COA covering:

• Assay (on dry basis) - ≥99.0%
• Transmittance, Specific Rotation, Loss on Drying, pH
