DESCRIPTION
E628 Dipotassium Guanylate is the dipotassium salt of 5'-guanylic acid, and E628 Dipotassium Guanylate is a 5'-ribonucleotide used in flavor systems for its potent umami synergy.
E628 Dipotassium Guanylate has limited umami effect alone, but E628 Dipotassium Guanylate strongly amplifies umami when combined with glutamate, producing a much stronger savory effect than either component alone.
E628 Dipotassium Guanylate is often used together with inosinate salts in nucleotide blends, and these blends provide broad savory enhancement and improved taste rounding in many seasoning applications.
E628 Dipotassium Guanylate provides potassium instead of sodium, and this makes E628 Dipotassium Guanylate useful for sodium-reduction strategies while maintaining strong nucleotide synergy.
E628 Dipotassium Guanylate can influence taste and salt perception, and potassium salts can introduce bitter or metallic notes at higher levels, so sensory optimization is important.
E628 Dipotassium Guanylate should be used according to applicable food additive regulations and good manufacturing practices for the target market.
E628 Dipotassium Guanylate is typically supplied as a white to off-white powder, and moisture control is important to prevent caking and preserve flow.
E628 Dipotassium Guanylate should be protected from high humidity and excessive heat to maintain consistent performance.
E628 Dipotassium Guanylate is generally compatible with typical seasoning processes, but pH and ionic strength can affect solubility in some systems.
E628 Dipotassium guanylate is the potassium salt of guanylic acid (a guanine-based 5’-ribonucleotide) used as a flavor enhancer for umami taste.
E628 Dipotassium guanylate is typically supplied as a white crystalline powder with good water solubility.
E628 Dipotassium guanylate is used at very low levels because it has strong taste synergy with glutamates.
E628 Dipotassium guanylate delivers umami enhancement most effectively when combined with glutamic acid or glutamate salts.
E628 Dipotassium guanylate is often used together with inosinate salts as part of mixed nucleotides in savory foods.
E628 Dipotassium guanylate is used in soups, seasonings, snacks, sauces, and processed foods to increase savory intensity.
E628 Dipotassium guanylate performance depends on formulation matrix, pH, salt balance, and processing conditions.
E628 Dipotassium guanylate should be stored in tightly closed containers in a cool, dry place to prevent moisture pickup and preserve quality.
E628 Dipotassium guanylate is valued for strong umami synergy, high efficiency at low dosage, and broad usefulness in savory flavor systems.

Seek medical attention if irritation persists.
Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs.
Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care as needed.
HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Use clean, dry equipment to prevent moisture pickup and clumping.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust where dust may be generated during powder transfer.
Minimize airborne particulate accumulation in enclosed areas.
Storage:
Store in tightly closed containers in a cool, dry place.
Protect from moisture to prevent caking and maintain potency and flow.
Keep away from strong odors and contaminants to preserve sensory neutrality.
Spill and Leak Procedures:
Sweep up spilled powder and avoid dust generation.
Collect into suitable containers for reuse or disposal according to local regulations.
Clean residues with water if needed and dry the area to prevent slip hazards.
Handling Precautions:
Formulate with glutamates because E628 Dipotassium Guanylate is most effective as an umami synergist rather than a standalone enhancer.
Optimize dosage carefully because small changes in E628 Dipotassium Guanylate can strongly affect savory intensity in synergy systems.
Evaluate potassium taste impact when using E628 Dipotassium Guanylate for sodium reduction because potassium salts can add slight bitterness at higher levels.
