Calcium guanylate

Calcium guanylate (CAS 38966-30-2), also known by its food additive designation E629, is the calcium salt of guanylic acid used as a flavor enhancer in processed food manufacturing.

It belongs to the nucleotide family of umami-potentiating compounds, functioning synergistically with glutamates to intensify savory taste profiles at low use levels in various applications.

In processed and convenience foods, including soups, sauces, snack seasonings, and instant noodles, E629 amplifies umami character when blended with monosodium glutamate or disodium inosinate.

This synergy reduces the total flavor additive load required for a product. Manufacturers of low-sodium formulations use it to maintain taste intensity while cutting salt content effectively.

This provides a commercially significant benefit in reformulation projects. In pharmaceutical applications, it serves as a nucleotide source in specialized nutritional products and oral formulations.

Calcium guanylate is supplied as a white crystalline powder. It is available in food-grade quality meeting specifications relevant to E629 compliance under EU food additive regulations.

The material also meets equivalent frameworks in other global markets. Pharmaceutical-grade material is available for buyers requiring documentation aligned with compendial or GMP sourcing standards.
