Import Disodium 5-Ribonucleotides — Buy in wholesale FOB from Supplier in China

Disodium 5-ribonucleotides, also known as E635 or I+G, is a food additive composed of disodium inosinate (IMP) and disodium guanylate (GMP) in a 1:1 ratio, synthesized from nucleic acid precursors. The product appears as a white to light yellow crystalline powder with an assay range of 97.0% to 102.0% for IMP+GMP combined, and each component is tightly controlled between 48.0% and 52.0%. It is not a standalone flavor but a synergistic enhancer that amplifies umami when combined with monosodium glutamate, particularly in processed foods where natural glutamates are present.

The material is manufactured through chemical synthesis, with strict limits on impurities: heavy metals capped at 10 ppm, arsenic at 1.0 ppm, and lead at 1 ppm. Transmittance exceeds 95.0% at 500 nm, indicating high purity, and pH is maintained between 7.0 and 8.5. Microbiological standards require total aerobic bacteria under 1,000 cfu/g, yeast and mold under 100 cfu/g, and negative results for coliform, E. coli, and Salmonella. These levels align with standard international food additive specifications for nucleotide enhancers, though no certification claims are made by the supplier.

This additive is primarily used in savory snacks, instant noodles, sauces, and ready-to-eat meals where flavor intensity is critical. Buyers include manufacturers of processed foods in Asia, Europe, and North America seeking cost-effective umami enhancement. Packaging is typically in 25 kg fiber drums with inner polyethylene lining. Trade terms are not stated; buyers must confirm MOQ, lead time, and Incoterms directly with the supplier. The product is shipped from Nanjing, China, and requires compliance with local food additive regulations upon import.

Dinayen Enterprise Management is a supplier based in Nanjing, China, with a physical address listed at Suning Wisdom Valley. The company is categorized as a harbor-tier supplier, indicating a baseline level of verification on the platform, but no certification documents, years in business, or export history are disclosed. The listing does not mention production capacity, staff size, or client names. The supplier claims experience in exporting this additive for nearly ten years, but no evidence or third-party validation is provided.

The company's profile shows zero response rate and no average response time, suggesting limited communication capacity or operational responsiveness. Buyers should treat this as a manufacturer-direct source with minimal public traceability. There is no indication of GMP, ISO, or HACCP certification. The supplier's role is limited to sourcing and exporting; no details about in-house synthesis, quality control labs, or R&D are present. Due diligence must be performed directly with the supplier before placing orders.
