Microencapsulated Ferrous Fumarate （50%, GMS/CSD）

What is Microencapsulated Ferrous Fumarate (50%, GMS/CSD)?

Microencapsulated Ferrous Fumarate (50%, GMS/CSD) is a food-grade iron supplement featuring ferrous fumarate (C₄H₂FeO₄, CAS: 141-01-5) as the core material encapsulated by mono and diglycerides as the wall material via spray drying technology, appearing as dark brown free-flowing fine granules insoluble in water. Making it suitable for food fortification, dietary supplement formulations, and animal feed premix applications.

1. Microencapsulated Iron Source with Masked Taste

Ferrous fumarate is encapsulated by mono and diglycerides as the wall material through microencapsulation technology, effectively masking the metallic iron taste and reducing undesirable organoleptic attributes. This enables seamless integration into a wide range of food and supplement formulations without compromising sensory quality.

2. High Iron Content for Efficient Fortification

With a standard iron content of 50.0%–60.0% (typical value 54%), this premix delivers a concentrated and reliable iron source, allowing formulators to achieve target iron levels with lower addition rates. This supports precise dosing accuracy and cost-effective formulation design across tablet, capsule, and powder mix applications.

3. Excellent Flowability and Sieving Performance

The product appears as dark brown free-flowing fine granules with 100% passing 20 mesh and ≥95% passing 40 mesh. The microencapsulated granular format ensures consistent powder flowability and blend homogeneity, supporting accurate dosing and uniform mineral distribution in tablet compression, capsule filling, and industrial powder mixing processes.

1. Iron-Fortified Staple Foods and Condiments

Due to its water insolubility and masked iron taste, this premix is ideal for dry fortification of wheat flour, rice, salt, and soy sauce without altering the sensory profile of the final product.

2. Infant Formula and Baby Food

The microencapsulation technology effectively masks the metallic taste, making it suitable for infant formula and complementary foods where flavor neutrality and palatability are critical.

3. Pharmaceutical and Nutraceutical Iron Supplements

Well-suited for tablet, capsule, and chewable supplement manufacturing, where the microencapsulated wall material reduces gastrointestinal irritation and masks the characteristic iron aftertaste.

4. Veterinary and Aquaculture Feed Premixes

Provides a palatable, non-irritating iron source for neonatal animal feed (especially piglets) and aquaculture premixes, while preventing iron-induced oxidative damage to other feed components.

Q1: What is microencapsulated ferrous fumarate and how does the microencapsulation process work?

A: Ferrous fumarate is encapsulated by mono and diglycerides as wall material through microencapsulation technology, masking the metallic iron taste and reducing undesirable organoleptic attributes. Tricalcium phosphate is added as an anti-caking agent. The product appears as dark brown free-flowing fine granules insoluble in water, with iron content of 50.0%–60.0% (typical value 54%).

Q2: Is this product suitable for human dietary supplements and functional foods?

A: Yes. The product meets food-grade quality specifications with strictly controlled heavy metal and microbiological parameters. It carries extensive clean-label certifications including Gluten-free, GMO-free, Vegan/Vegetarian, Lactose free, Starch free, and BSE/TSE-free, making it suitable for dietary supplement and functional food formulations.

Q3: What are the solubility and particle size characteristics of this premix?

A: The premix appears as dark brown free-flowing fine granules that are insoluble in water. The particle size ensures 100% passing 20 mesh and ≥95% passing 40 mesh, delivering consistent flowability and blend homogeneity for tablet, capsule, and powder mix manufacturing.

Q4: What clean-label certifications and contaminant-free declarations does this product carry?

A: The product carries extensive declarations including Gluten-free, GMO-free, Vegan/Vegetarian, Lactose free, Starch free, BSE/TSE-free, Antibiotics free, Hormone free, Pesticide free, Irradiation free, Melamine free, Mineral Oil free, Mycotoxins free, PAH free, PCB free, and CMR/SVHC compliant certifications.

Q5: How should this product be stored and what is its shelf life?

A: Store in a cool, dry place at room temperature, protected from direct sunlight and moisture. The container must remain tightly sealed after opening. The product is packaged in fiber cartons with aluminum inner bags, 25kg per carton. Under proper storage conditions, the product maintains its specified quality parameters for 18 months from the date of manufacture.
