Dipotassium guanylate

Dipotassium guanylate (CAS 3254-39-5), also designated E628, is the dipotassium salt of guanylic acid used as a flavor enhancer in food manufacturing.

Where is Dipotassium guanylate used?

• Processed foods: umami depth in soups, broths, seasonings and snack coatings
• Instant noodles and bouillon: with monosodium glutamate or disodium inosinate for consistent flavor at reduced additive loads
• Meat processing: flavor retention in cured and restructured products
• Pharmaceuticals: nucleotide source in nutritional preparations and oral formulations
• It amplifies savory, umami taste profiles, typically with other nucleotides.

Good to know: Works with glutamates to achieve synergistic flavor intensification at low use levels. Food-grade material conforming to E628 purity specifications is the standard commercial form.
