What is Monosodium Glutamate CAS 142-47-2?

Monosodium Glutamate CAS 142-47-2 is the sodium salt of L-glutamic acid, commonly called MSG or sodium glutamate. Commercial food-grade MSG is usually supplied as the monohydrate with formula C5H8NO4Na.H2O.

It is generally produced by fermentation of carbohydrate sources such as corn, rice, or tapioca using Corynebacterium strains, followed by purification and neutralization with sodium hydroxide. This is a controlled biological process rather than chemical synthesis from petroleum.

How does Monosodium Glutamate enhance flavor?

It provides umami, the savory taste associated with glutamate, and intensifies meaty or broth-like notes in foods. Because it contributes less sodium by weight than table salt, formulators can sometimes reduce total sodium while maintaining savory intensity.

What grades and regulatory identities apply?

Food-grade MSG is commonly supplied under E621, FCC, or GB/T 8967 specifications. Pharmaceutical or specialty grades may have tighter impurity, microbial, and assay controls depending on the intended market.

What storage and handling conditions should be followed?

Store Monosodium Glutamate in sealed, dry packaging away from moisture and strong oxidizing agents. Keep it in a cool, clean area to protect flowability, appearance, and sensory quality.

Product Description

Monosodium Glutamate, CAS 142-47-2, also called MSG or sodium glutamate, is the sodium salt of L-glutamic acid.

Synonyms: MSG; Sodium glutamate; Monosodium L-glutamate; L-Glutamic acid monosodium salt; Sodium 2-aminopentanedioate.

CAS: 142-47-2.

It is usually supplied as the monohydrate, with white crystalline granules or powder and a distinct umami taste.

It has a purity of not less than 99.0% and a specific rotation of about +24.8° to +25.3°.

It is produced by fermentation of carbohydrate sources such as corn, rice or tapioca, followed by purification and neutralization.

It provides umami and intensifies meaty or broth-like notes in foods.

It is used in bouillon cubes, soup mixes, stocks and sauces.

It is applied to potato chips, crackers and savory snacks for flavor boosting.

It is used in sausages, hams and preserved meats to improve taste and palatability.

It is essential in Asian and international cuisines for marinating meats and seasoning stir-fries, stews and soups.

It is a key ingredient in instant noodles and pre-packaged meals.

It can contribute less sodium by weight than table salt, helping reduce total sodium while maintaining savory intensity.

Confirm appearance, purity, transmittance, specific rotation, loss on drying, pH, chloride, iron, heavy metals, arsenic, sulfate and mesh size.

Store in a cool, dry, well-ventilated area away from toxic, harmful or strong-smelling goods.

Keep containers tightly closed, as the product can cake in high humidity.

Confirm packaging with the requested quantity and destination requirements.
