Food Grade Ferrous Sulfate Heptahydrate

Product Basic Parameters

Standard chemical name: Ferrous Sulfate heptahydrate. Molecular formula: FeSO₄·7H₂O. Exact molecular weight: 278.01. CAS registration number: 7782-63-0. All parameters comply with international industrial and food-grade standard calibration data for accurate batch traceability and customer parameter verification.

Physical Properties

The product presents blue-green crystalline or granular form with no peculiar odor and natural astringent taste. It features stable physical and chemical phase characteristics under conventional storage conditions. Efflorescence occurs when exposed to dry ambient air. Oxidation reaction takes place in humid air, generating brown-yellow basic ferric sulfate on the product surface. It delivers complete water solubility and shows no solubility in ethanol, meeting the solvent adaptability requirements of downstream production processes.

Industrial & Food Applications

The product serves two core downstream application scenarios with stable ingredient performance. It is applied as a standard iron fortifier for nutritional supplement production, supplementing iron elements in formula materials. It is also adopted as a color fixing and conditioning agent for fruit and vegetable processing, stabilizing the natural color tone of fresh produce and processed finished products. The product meets conventional industry usage standards for food additives and nutritional raw materials.

Standard Packaging Specification

Double-layer packaging structure is adopted for all finished products to ensure storage and transportation integrity. The inner layer is made of food-grade and industrial-grade compatible polyethylene sealing bag to isolate dust, moisture and external impurities. The outer layer is thickened compound plastic woven bag for physical compression and tear resistance. Each packaged unit has a fixed net weight of 25kg, with unified packaging specifications for convenient inventory counting, palletizing and container loading.

Storage & Transportation Guidelines

Finished products require storage in dry, well-ventilated indoor warehouses with stable ambient temperature and low humidity to avoid property changes caused by environmental fluctuation. During road and sea transportation, goods shall be kept away from high-temperature heat sources and humid environments. Manual and mechanical unloading shall be operated gently to prevent packaging breakage and product leakage. Independent storage and transportation arrangement is mandatory, with strict separation from all toxic and hazardous substances to avoid cross-contamination, complying with international chemical material logistics safety norms.
