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.

Where is Calcium guanylate used?

• Processed and convenience foods: amplifies umami in soups, sauces, snack seasonings and instant noodles when blended with monosodium glutamate or disodium inosinate
• Low-sodium formulations: maintains taste intensity while cutting salt content
• Pharmaceutical applications: nucleotide source in specialized nutritional products and oral formulations
• It functions synergistically with glutamates to intensify savory taste profiles at low use levels.

Good to know: Belongs to the nucleotide family of umami-potentiating compounds; synergy with glutamates reduces the total flavor additive load required.
