What Is L-Glutamic Acid Powder?

L-Glutamic Acid Powder is the free acid form of the non-essential alpha-amino acid L-Glutamate, the levorotatory enantiomer having chemical formula C₅H₉NO₄. It is a white crystalline powder. The sodium salt derivative (MSG) has a different pH behaviour and solubility profile.

It is made by large scale fermentation of Corynebacterium glutamicum using non-GMO carbohydrate sources. This fermentation technique provides high enantio-purity (>99%), stable impurity profiles and robust bio-activity – characteristics sometimes missing in lower-grade alternatives.

It operates in the organism as a major excitatory neurotransmitter in the central nervous system and as an important nitrogen donor in amino acid metabolism. It is industrially used as a chiral building block, pH buffer and biological precursor in a variety of industries.

Third-Party Test Report

Besides the internal testing, Hongda also verifies the quality of its products by SGS and Eurofins, two internationally recognised testing companies. Third-party reports include:

· Pesticide residue testing

· Heavy metals (Pb, As, Hg, Cd)

· Microbiological study

· Optical rotation (specific)

• Nutrition labelling

Traceability of each batch. Reports can be provided on request either prior to or after an order is placed.

Product Specification

L-Glutamic Acid Powder Advantages

≥99% Purity with Consistent Batch Quality

The fermentation-based technique provides an enantiomeric excess of >99% which is necessary for peptide medicine synthesis and parenteral amino acid infusions. Each batch is tested by HPLC, UV and GC at Hongda’s own SGS standardised lab before shipping.

Low Hygroscopicity – Fewer Caking Problems

This product has minimal water absorption compared to several other amino acids. In the sealed original packaging and at humidity levels below 60%, it will retain its free flowing crystalline form during the shelf life, resulting in less processing challenges on your production line.

Multi-Certification Compliance

Certified Kosher, Halal, BRC, Organic (EU & NOP), ISO9001, ISO22000, cGMP (2025) the product meets the standards required for export to US, European and Asian markets without the need for extra re-testing.

Dependable supply. 3,000 tons per year.

Hongda has more than 10 contemporary production lines and 3,000 m2 warehouse and the raw material supply is stable as we have professional planting bases, so we can provide adequate inventory for small trial orders and also large supply contracts.

L-Glutamic Acid Powder Application

Pharmaceutical & Parenteral Nutrition

Used as a starting material for the production of Folic Acid (Vitamin B9) and polypeptide therapies. In clinical amino acid infusion formulations (IV fluids) it has been shown to enhance liver function in patients with hepatic encephalopathy, an application requiring tight endotoxin control and ultra-pure grades for compatibility with the blood-brain barrier.

Beauty & Personal Care

Primary substrate for production of Sodium Cocoyl Glutamate and other gentle amino acid surfactants. In skin creams, it acts as a natural moisturising factor (NMF) component and pH adjuster, keeping skin neutral pH at 5.5 — which is critical for microbiota balance and barrier integrity.

Food Science & Flavour Control

It is not only a precursor of MSG, but also a precise flavour modifier and pH regulator in acid food matrices. It adds umami depth without the high sodium concentration of salt-based alternatives, which is important for clean label formulation.

Foliar Feeds & Agriculture

When used as a chelating agent in foliar sprays it combines with micro nutrients such as Ca, Mg and Zn to increase leaf cuticle absorption. It also increases stomatal opening under drought or severe salinity stress without the energetic expense of nitrate reduction to sustain photosynthesis.

Animal Nutrition.

It is used in starter feeds for high-yield animals to promote the development of intestinal morphology and enhance nutrient absorption, especially in heat-stress settings where the efficiency of digestion is reduced.

Production Process

Hongda L-Glutamic Acid is produced by a highly controlled fermentation and extraction process:

1. Raw Material Selection — Traceable non-GMO carbohydrate feedstocks from specific planting bases

2. Microbial Fermentation - Fermentation of Corynebacterium glutamicum at controlled temperature and pH

3. Separation and crystallization—Isoelectric precipitation at pH 3.22, followed by washing and drying

4. Purification — Refining through multiple stages to achieve purity ≥99%

5. Quality testing – HPLC purity, heavy metals, microbiological and optical rotation analysis

6. Packaging 25 kg/drum, fibre drum outer packaging, double-layer PE inner bag, in a purification workshop of 100000 grade

FAQ

Q1: What is the difference between the product and MSG?

A: L-Glutamic Acid is the free acid form. It is less water soluble and has an acidic pH. MSG is a sodium salt used to give rapid flavour and solubility. They provide diverse technical functions in the formulation.

Q2: What is the effect of pH on solubility?

A: Lowest solubility at the isoelectric point (pH 3.22) This pH value is critical in liquid formulation work because dissolving rate increases dramatically above and below it.

Q3: Is the product made by fermentation or chemical synthesis?

A: It is created by natural fermentation on non-GMO carbohydrate sources, resulting in excellent bio-activity and a clean impurity profile.

Q4: How to storage the powder to avoid caking?

A: Keep in the original unopened package in a cool, dry place with humidity below 60%. Under correct conditions it remains free flowing and is low in hygroscopicity.

Q5: Is the product in accordance with international export standard?

A: Yeah. It routinely meets USP and FCC monograph specifications and is Kosher, Halal and Organic certified for key export markets.

Q6: May I have samples before placing an order in bulk?

Q: Yeah. Samples are available from 20 to 100 g. For a sample with complete documentation, please Contact Us at duke@hongdaherb.com.
