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. It amplifies savory, umami taste profiles, typically in combination with other nucleotides.

This additive works with glutamates to achieve synergistic flavor intensification at low use levels. In processed food production, E628 is incorporated into soups, broths, seasonings, and snack coatings to boost umami depth without increasing sodium content.

Instant noodle and bouillon manufacturers use it alongside monosodium glutamate or disodium inosinate to deliver consistent flavor profiles at reduced additive loads. This efficiency makes it a preferred choice for large-scale industrial food production.

In meat processing, it supports flavor retention in cured and restructured products where taste consistency across batches is a formulation priority. It ensures that the savory profile remains stable throughout the shelf life of the product.

Pharmaceutical applications include use as a nucleotide source in specialized nutritional preparations and oral formulations where palatability enhancement is required. It helps mask bitter notes and improves the overall patient experience with oral medications.

Dipotassium guanylate is supplied as a white crystalline powder. Food-grade material conforming to E628 purity specifications is the standard commercial form available to food manufacturers and formulators globally.

It is typically offered in bulk quantities suited to industrial seasoning and flavor blending operations. The material is handled according to strict safety protocols to ensure it meets the necessary regulatory requirements for food and pharma use.
