Description

Sodium L-Glutamate is the sodium salt of the naturally occurring L-glutamic acid, a key amino acid. It is a fundamental ingredient widely recognized for its flavor-enhancing properties and its role in biochemical processes. This high-purity compound is essential for manufacturers in the food, pharmaceutical, and nutraceutical industries seeking reliable, consistent quality for their formulations. Its consistent performance makes it a critical component for products where purity and bioactivity are paramount.

Application

• Food Industry: Primarily used as a flavor enhancer (monosodium glutamate, MSG) in savory foods, soups, sauces, and processed meats.
• Pharmaceuticals: Serves as a precursor in the synthesis of various drugs and as an ingredient in parenteral nutrition solutions and amino acid supplements.
• Nutraceuticals & Supplements: Incorporated into dietary supplements and health products for its role in protein synthesis and as a neurotransmitter precursor.
• Biochemical Research: Used as a defined component in cell culture media, microbiological growth media, and as a standard in analytical chemistry.
• Cosmetics: Functions as a skin conditioning agent and hair conditioner in personal care formulations.
• Animal Feed: Added to feed to improve palatability and support growth in livestock and poultry.

Quality Control

Our Sodium L-Glutamate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and safety, aligning with standards such as FCC (Food Chemicals Codex) and JP (Japanese Pharmacopoeia). Comprehensive testing includes assay, optical rotation, and limits for specific impurities. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in original packaging or equivalent moisture-barrier containers to prevent caking and degradation. Keep away from incompatible materials.
