Basic Information
Product Name: IRON PEPTONATE
CAS Number: 91079-40-2
Alias: Ferric Peptonate, Peptone Iron Complex
Chemical Full Name: Complex chelate of ferric ion with protein peptone hydrolysate
Molecular Formula: Mixed polypeptide-ferric complex (no fixed single molecular formula)
Molecular Weight: Mixed macromolecular complex
EINECS: Not available
Structural Information
- Structure Type: Water-soluble polypeptide ferric chelate nutritional raw material
- Structural Features: Small molecular peptone hydrolyzed from animal/plant protein, peptide carboxyl & amino groups coordinate with ferric iron to form stable water-soluble complex; avoids iron ion precipitation under neutral pH, high gastrointestinal absorption rate
- Characteristic: Organic ferric supplement for pharmaceutical, culture medium, food nutrition fortifier
Physical & Chemical Properties
- Appearance: Brown to dark brown fine powder
- Odor: Faint characteristic protein peptone odor
- Solubility: Freely soluble in water to form brown transparent solution; insoluble in ethanol, acetone, ether
- Stability: Stable under sealed dry cool storage; resistant to precipitation in neutral and weakly alkaline aqueous systems; heat stable under conventional sterilization temperature; will dissociate under strong acid/strong alkali heating
- pH (1% aqueous solution): 4.5–7.0
Synthesis & Applications
Production Method
Enzymatic hydrolysis of animal protein to obtain peptone, chelation reaction with ferric salt solution, decolorization, spray drying to form iron peptone powder.
Main Applications
- Pharmaceutical raw material: Oral iron supplement raw material for iron-deficiency anemia auxiliary treatment
- Microbiological culture medium: Iron source nutrient for bacterial, fungal microbial culture
- Food & health care additive: Organic iron nutrition fortifier for functional food, infant nutrition supplements
- Veterinary medicine raw material: Iron supplement for livestock and poultry feed additives
