Description

L(+)-Monosodium Glutamate Monohydrate is the monohydrate form of the sodium salt of L-glutamic acid, a high-purity flavor enhancer widely recognized for its umami taste. This specific enantiomer is critical for ensuring product consistency, safety, and efficacy in sensitive applications. It is an essential ingredient for manufacturers in the food and beverage, pharmaceutical, and nutraceutical industries seeking to enhance savory flavor profiles or utilize glutamic acid derivatives in biochemical processes.

Application

• Food & Beverage Industry: Primary use as a flavor enhancer (umami) in soups, sauces, seasonings, snacks, and processed meats.
• Pharmaceutical Formulations: Used as an excipient or a source of L-glutamate in infusion solutions and specific medicinal products.
• Nutraceuticals & Dietary Supplements: Incorporated into supplements aimed at supporting cognitive function or as a metabolic intermediate.
• Microbiological Culture Media: Serves as a nitrogen source in the preparation of specialized culture media for fermentation and research.
• Biochemical Research: Used as a standard or reagent in enzymatic studies and biochemical assays.
• Animal Feed Additive: Employed to improve the palatability and intake of certain feed formulations.

Quality Control

Our L(+)-Monosodium Glutamate Monohydrate is manufactured under strict quality management systems. It is typically produced to meet or exceed standards such as Food Chemical Codex (FCC) and USP-NF for relevant grades, ensuring identity, strength, purity, and quality. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters like assay, optical rotation, and impurity profiles, confirming compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature. Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking. Keep away from incompatible materials.
