DESCRIPTION

E629 Calcium Guanylate is the calcium salt of 5'-guanylic acid, and E629 Calcium Guanylate is a 5'-ribonucleotide used in flavor systems for its potent umami synergy.
E629 Calcium Guanylate has limited umami effect alone, but E629 Calcium Guanylate strongly amplifies umami when combined with glutamate, producing a much stronger savory effect than either component alone.
E629 Calcium 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.

E629 Calcium Guanylate provides calcium instead of sodium, and this can be useful for specific mineral positioning or sodium reduction strategies, but calcium salts can have different solubility and sensory behavior.
E629 Calcium Guanylate can influence mouthfeel and may contribute slight chalkiness in some systems at higher usage levels, so sensory optimization and solubility testing are important.
E629 Calcium Guanylate should be used according to applicable food additive regulations and good manufacturing practices for the target market.

E629 Calcium Guanylate is typically supplied as a white to off-white powder, and moisture control is important to prevent caking and preserve flow.
E629 Calcium Guanylate should be protected from high humidity and excessive heat to maintain consistent performance.
E629 Calcium Guanylate is generally compatible with typical seasoning processes, but pH and ionic strength can affect solubility in some systems.

E629 Calcium guanylate is the calcium salt of guanylic acid (a guanine-based 5’-ribonucleotide) used as a flavor enhancer for umami taste.
E629 Calcium guanylate is typically supplied as a white crystalline powder with moderate water solubility compared with sodium salts.
E629 Calcium guanylate is used at very low levels because it has strong taste synergy with glutamates.

E629 Calcium guanylate delivers umami enhancement most effectively when combined with glutamic acid or glutamate salts.
E629 Calcium guanylate is often used with inosinate salts as part of mixed nucleotides in savory foods.
E629 Calcium guanylate is used in soups, seasonings, snacks, sauces, and processed foods to increase savory intensity.

E629 Calcium guanylate performance depends on formulation matrix, pH, salt balance, and processing conditions.
E629 Calcium guanylate should be stored in tightly closed containers in a cool, dry place to prevent moisture pickup and preserve quality.
E629 Calcium guanylate is valued for strong umami synergy, high efficiency at low dosage, and usefulness as an alternative nucleotide salt in savory flavor systems.

FIRST AID

Inhalation:
Move to fresh air if dust is inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing dust during powder handling.

Skin Contact:
Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
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 E629 Calcium Guanylate is most effective as an umami synergist rather than a standalone enhancer.
Optimize dosage carefully because small changes in E629 Calcium Guanylate can strongly affect savory intensity in synergy systems.
Evaluate solubility and mouthfeel impact because calcium salts can be less soluble and may affect texture in some applications.
