DESCRIPTION
E579 Ferrous Gluconate is the ferrous salt of gluconic acid, and E579 Ferrous Gluconate supplies iron in the +2 oxidation state, which is generally associated with good bioavailability in nutrition applications.
E579 Ferrous Gluconate can oxidize to ferric forms in the presence of oxygen and oxidizing conditions, and this oxidation can change color and reduce stability, so formulation and packaging controls are important.
E579 Ferrous Gluconate is often preferred over some inorganic iron salts because E579 Ferrous Gluconate can have lower astringency and reduced metallic taste at comparable iron doses in certain matrices.
E579 Ferrous Gluconate can interact with polyphenols, phosphates, and some proteins, and these interactions can affect solubility, color, and taste, so compatibility testing is required for each product.
E579 Ferrous Gluconate should be used according to applicable food additive regulations and good manufacturing practices for the target market.
E579 Ferrous Gluconate should be protected from moisture and excessive heat, and E579 Ferrous Gluconate should be stored away from strong oxidizers to preserve iron(II) stability.
E579 Ferrous Gluconate is typically supplied as a yellowish to gray-green powder with defined assay, and consistent particle size supports uniform blending in premixes.
E579 Ferrous Gluconate may be used with stabilizing acids or chelating strategies in some formulations to improve iron stability, but chelation can also affect bioavailability and taste profile.
E579 Ferrous Gluconate should be stored in tightly closed containers to minimize oxygen exposure and maintain quality.
E579 Ferrous gluconate is the iron(II) salt of gluconic acid and is used as a food additive and iron source.
E579 Ferrous gluconate is typically supplied as a yellowish to greenish powder or granules and is soluble in water.
E579 Ferrous gluconate provides ferrous iron, which can be more readily absorbed than some ferric forms in many nutrition contexts.
E579 Ferrous gluconate is used for iron fortification in foods and supplements and as a color fixative in black olive processing.
E579 Ferrous gluconate can contribute metallic taste or promote oxidation if not properly formulated, so antioxidants and chelation strategies may be used.
E579 Ferrous gluconate performance depends on pH, oxygen exposure, and interactions with proteins, polyphenols, and other ingredients.
E579 Ferrous gluconate should be stored in tightly closed containers in a cool, dry place and protected from moisture and excessive oxygen exposure.

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 or if a large amount is swallowed.
Iron ingestion can be harmful in high amounts, especially for children, so keep out of reach and follow dosage guidance.
Note to Physicians:
Treat symptomatically.
Consider iron exposure and gastrointestinal irritation based on amount ingested.
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.
Prevent contamination and use clean, food-grade equipment for weighing and blending.
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 and oxygen exposure to reduce oxidation and color change.
Keep away from strong oxidizers and reactive chemicals.
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:
Control oxidation risk because E579 Ferrous Gluconate can oxidize and change color and performance in air-exposed or high-moisture environments.
Evaluate formulation interactions because iron can catalyze oxidation and react with polyphenols and phosphates, affecting taste and color.
Rotate stock using FIFO practices to maintain consistent quality and predictable fortification performance.
