Description

Disodium 5'-Ribonucleotide is a high-purity nucleotide salt, a key ingredient for enhancing savory flavor profiles. This compound is valued for its synergistic effect with monosodium glutamate (MSG), significantly boosting umami taste while allowing for sodium reduction. It is an essential component for manufacturers in the food and beverage, nutraceutical, and biotechnology sectors seeking to improve product palatability and develop specialized formulations.

Application

• Food Flavor Enhancer: A critical ingredient in savory snacks, instant noodles, soups, sauces, seasonings, and processed meats to intensify umami taste and create a more rounded flavor profile.
• Sodium Reduction Agent: Used in low-sodium or "light" food products to maintain a full, savory flavor while reducing overall salt (NaCl) content.
• Nutraceutical & Dietary Supplement: Incorporated into health supplements and medical nutrition products for its role as a nucleotide source, supporting various metabolic functions.
• Cell Culture & Biotechnology: Serves as a component in specialized cell culture media and fermentation processes for the production of vaccines, antibodies, and other biologics.
• Pharmaceutical Intermediate: Used in the synthesis of more complex nucleotide-based active pharmaceutical ingredients (APIs) and antiviral drugs.
• Animal Feed Additive: Enhances the palatability of feed for livestock and aquaculture, promoting feed intake and growth performance.

Quality Control

Our Disodium 5'-Ribonucleotide is manufactured under strict quality systems. We offer grades compliant with major international standards, including FCC (Food Chemicals Codex) and JECFA specifications for food applications, as well as high-purity grades for pharmaceutical and biotech use. Every batch undergoes rigorous analytical testing. Certificates of Analysis (COA) documenting purity, identity, and safety parameters are available upon request to ensure full traceability and compliance for your production needs.

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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
