Product Overview

L-Glutamic Acid (CAS 56-86-0) is a non-essential acidic amino acid and the parent compound from which monosodium glutamate (MSG), the world’s most widely used flavor enhancer, is produced. It is a foundational industrial amino acid raw material with broad applications in food flavoring, feed nutrition and biochemical manufacturing.

We supply food grade and feed grade L-Glutamic Acid. Food grade is primarily used as a raw material for MSG production and as a direct umami flavor enhancer in condiments, compound seasonings and processed foods. It also acts as key substrate for enzymatic synthesis of γ-aminobutyric acid (GABA) for functional food and sports nutrition formulas. Feed grade serves as an amino acid nutritional additive in animal feed formulations.

Compliant with USP, EP, CP, AJI and FCC standards, and certified by ISO9001, ISO22000, HALAL, KOSHER and HACCP for global export.

 

Product Characteristics

1.Parent compound of MSG L-Glutamic Acid is the direct precursor for monosodium glutamate (MSG) production, making it a foundational raw material for the global flavor enhancer industry.

2.Natural umami taste profile Delivers characteristic savory (umami) taste, widely used to enhance flavor in condiments, soups, sauces and snack foods.

3.White crystalline powder Stable crystalline form with good flow properties, suitable for bulk industrial production and storage.

4.Acidic pH, limited cold-water solubility Saturated solution pH around 3.2; more soluble in hot water. The sodium salt (MSG) is preferred for direct beverage use due to higher solubility.

5.Dual food and feed supply Available in food grade for flavor, MSG manufacturing and biochemical synthesis, and feed grade for animal nutrition fortification.

 

Main Functions

1.Raw material for MSG (monosodium glutamate) production Primary industrial use: converted to sodium salt (MSG) for global flavor enhancer manufacturing.

2.Direct umami flavor enhancement Added directly to condiments, compound seasonings, instant soup bases, meat products and savory snacks to boost savory taste.

3.Food flavor improvement and masking Helps round out flavor profiles, reduces undesirable bitterness and enhances overall taste balance in processed foods.

4.Precursor raw material for GABA production L-Glutamic acid serves as the primary substrate for enzymatic synthesis of γ-aminobutyric acid (GABA). It is widely used by manufacturers to produce GABA for functional food and nutritional supplement formulations.

5.Sports nutrition & muscle metabolic support Supports protein metabolism and muscle recovery after intense exercise, used as an ingredient in sports nutrition formulas to ease exercise-induced fatigue.

6.Supports normal cognitive and intestinal function Participates in brain neurotransmitter metabolism and acts as an energy source for intestinal epithelial cells, supporting normal digestive and cognitive function.

7.Amino acid nutritional fortification in feed Serves as an amino acid additive in animal feed to support nutritional balance and growth performance.

8.Biochemical intermediate Used as a raw material for amino acid preparations and biochemical reagent production.

 

Main Applications

 

1. Food Industry & MSG Production (Core Application)

Food grade L-Glutamic Acid is predominantly used as the starting material for monosodium glutamate (MSG) production. It is also directly applied as a flavor enhancer (E620) in compound seasonings, soy sauce, hotpot bases, instant noodle seasoning, processed meat products and savory snacks. It improves umami taste and overall flavor balance in a wide range of processed food products.

 

2. Downstream Biochemical & Sports Nutrition

It acts as a key substrate for the enzymatic production of γ-aminobutyric acid (GABA). The derived GABA is widely used in functional food and sports nutrition formulations. L-Glutamic acid can also be added into sports nutrition blends to support muscle metabolism and post-exercise recovery.

 

3. Feed Industry (Secondary Application)

Feed grade L-Glutamic Acid is used as an amino acid nutritional additive in compound feed and premix formulations, supporting amino acid balance and nutritional supplementation for livestock and poultry.

 

4. Biochemical (Minor Application)

Used as a raw material for compound amino acid preparations and biochemical research reagents.
