Description

Glucose-Cysteine CAS NO 38325-69-8 is a specialized biochemical compound formed from the Maillard reaction between glucose and the amino acid L-cysteine. This product matters as a key flavor precursor and processing aid, essential for developing savory, meaty, and roasted flavor profiles in a controlled manner. It is primarily needed by manufacturers in the food and flavor industries seeking to enhance and standardize the taste of processed foods, savory snacks, and reaction flavors.

Application

• As a key flavor precursor in the production of savory reaction flavors (meat, poultry, seafood).
• For enhancing and standardizing umami and roasted notes in processed foods, soups, sauces, and gravies.
• In the development of natural meat flavorings and savory snack seasonings.
• As a processing aid to improve the aroma profile of pet foods and animal feed.
• For research and development in food science and flavor chemistry studies.
• Potential use in pharmaceutical intermediates or cosmetic applications requiring specific thiol derivatives.

Quality Control

Our Glucose-Cysteine is produced and tested under a rigorous quality management system. While typically supplied as a food-grade material, specifications can be tailored to meet customer requirements for purity and application performance. Certificates of Analysis (COA) documenting key parameters such as assay, identification, and moisture content are provided with each batch to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking. Keep away from incompatible materials.
