DESCRIPTION
E623 Calcium Diglutamate is a calcium salt associated with glutamic acid, and E623 Calcium Diglutamate releases glutamate in aqueous systems, which is responsible for umami taste perception.
E623 Calcium Diglutamate provides a standardized, consistent source of umami enhancement similar to other glutamate salts, but with calcium as the counterion, which changes mineral contribution and solubility behavior.
E623 Calcium Diglutamate can support reduced-sodium formulation strategies, but calcium salts can influence solubility, mouthfeel, and sometimes cause slight chalkiness at higher levels, so sensory optimization is important.
E623 Calcium Diglutamate shows synergy with 5'-ribonucleotides such as inosinate and guanylate, and this synergy can multiply perceived umami intensity when used together in seasonings.
E623 Calcium Diglutamate is typically produced by neutralizing glutamic acid with a calcium base followed by purification and drying to food-grade specifications.
E623 Calcium Diglutamate should be used according to applicable food additive regulations and good manufacturing practices for the target market.
E623 Calcium Diglutamate is typically supplied as a white to off-white powder, and E623 Calcium Diglutamate should be dispersed properly to ensure uniform distribution in dry mixes and seasonings.
E623 Calcium Diglutamate should be stored in tightly closed containers in a cool, dry place to prevent moisture pickup and caking.
E623 Calcium Diglutamate should be handled with good hygiene and dust control practices during bulk powder processing.
E623 Calcium diglutamate provides glutamate ions in solution, which activate umami taste receptors.
E623 Calcium diglutamate can provide flavor enhancement with different ionic contribution compared with sodium or potassium glutamate salts.
E623 Calcium diglutamate shows synergy with nucleotides such as inosinate and guanylate, boosting umami intensity.
E623 Calcium diglutamate is used in soups, snacks, seasonings, sauces, and processed foods to enhance savory taste.
E623 Calcium diglutamate performance depends on formulation salt balance, pH, and presence of synergistic umami ingredients.
E623 Calcium diglutamate should be stored in tightly closed containers in a cool, dry place to prevent moisture pickup and caking.
E623 Calcium diglutamate is valued for consistent umami impact and usefulness as an alternative glutamate salt in savory food applications.

Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.

HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Maintain good hygiene and clean-up practices in handling areas.
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 free-flowing behavior.
Keep containers properly labeled and protected from contamination.
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:
Optimize dosage because E623 Calcium Diglutamate affects umami intensity and taste balance, and excessive levels can create overly strong savory notes or mineral aftertaste.
Consider synergy with nucleotides because combining E623 Calcium Diglutamate with inosinate and guanylate can significantly increase perceived umami.
Rotate stock using FIFO practices to maintain consistent quality and predictable flavor enhancement performance.
