As a vital nutrient in the food and fermentation industries, Food Grade Manganese Sulfate (MnSO₄·H₂O) plays an indispensable role in human health and food production.
For international buyers looking to source high-quality ingredients, understanding the technical nuances and market dynamics of this product is key to making informed purchasing decisions. As a leading supplier of food grade minerals and additives, Greenhai Nutritionals provides this guide to help you navigate the essentials of this important compound.
Chemical Properties: The Basics of MnSO₄·H₂O
Understanding the identity of a product is the first step in ensuring quality. Food Grade Manganese Sulfate Monohydrate is an inorganic mineral compound. Here are its defining characteristics:
-
Molecular Formula: MnSO₄·H₂O
-
Molecular Weight: 169.02
-
CAS Number: 7785-87-7; 10034-96-5
-
Appearance: It typically presents as a pale pink, free-flowing granular powder. This distinct color is a visual indicator of its purity .
-
Solubility: It is highly soluble in water, which makes it an excellent carrier for manganese in liquid supplements and fermentation broths. It remains insoluble in alcohol .
-
Stability: The product is stable under normal storage conditions. It begins to lose its crystal water when heated above 200°C, which is an important factor during any high-heat processing
Function and Role: Why is it Essential?
Manganese is an essential trace element required for human health and microbial growth. In the context of food and pharma-nutrition, Food Grade Manganese Sulfate Monohydrate serves critical functions:
-
Nutritional Supplementation: It serves as a highly bioavailable source of manganese in dietary supplements and fortified food products. Manganese is a cofactor for numerous enzymes involved in bone metabolism, carbohydrate metabolism, and antioxidant function .
-
Fermentation Nutrient (Processing Aid): One of its most significant uses in the food industry is as a nutrient for microbial fermentation. It is added to fermentation media to support the healthy growth of bacteria and yeast cultures used in the production of various foods, dairy cultures, and beverages. Regulatory bodies like the Codex Alimentarius (CCFA) recognize its use as a microbial nutrient in food manufacturing .
-
Cryoprotectant: In bacterial cultures, it helps protect cells during freezing and drying processes, ensuring the viability of starter cultures used in yogurt and cheese production.
Global Market Demand: A Steady Growth Trajectory
In Greenhai Nutritionals researching, we found the international market for food grade manganese sulfate is substantial and growing. While a significant portion is dedicated to battery and agricultural grades, the demand for high-purity Food Grade and Pharmaceutical Grade material remains steady due to consistent needs in the health and food processing sectors.
-
Market Size: The global market for all Manganese Sulfate was valued at approximately US$ 554 million in 2025 and is projected to reach nearly US$ 1.24 billion by 2032. This growth represents a strong Compound Annual Growth Rate (CAGR) of around 13.0% .
-
Key Drivers: This growth is fueled not only by the electric vehicle (EV) battery sector but also by the increasing global demand for nutritional supplements, fortified foods, and complex fermented products. As the global population grows and seeks better nutrition, the need for essential minerals like manganese in the food chain increases .
-
Regional Insights: Asia Pacific, particularly China, is a major hub for both production and consumption. However, demand remains robust in North America and Europe, where strict food safety regulations drive the need for certified, high-quality ingredients .
How to Choose the Right Food Grade Manganese Sulfate
Selecting the right supplier and product specification is critical for food safety and regulatory compliance. Here, Greenhai Nutritionals provides 4 key factors international buyers should consider:
Verify Regulatory Compliance and Standards
Food grade manganese sulfate must meet strict purity guidelines to be safe for consumption. Always look for products that comply with international standards. The most common references for food safety are FCC (Food Chemical Codex) and USP (U.S. Pharmacopoeia) .
-
FCC Grade: Indicates suitability for food, beverage, and nutritional supplement applications .
-
Multi-Compendial: Greenhai Nutritionals offers material that meets both FCC and USP standards, simplifying your inventory for different markets .
Check the Certificate of Analysis (CoA)
A reliable supplier will always provide a CoA/TDS. For food grade manganese sulfate MnSO₄·H₂O, pay close attention to the purity assay and the limits for heavy metals. According to FCC&USP standards, typical specifications require :
-
Assay (Content): 98.0% – 102.0% of MnSO₄·H₂O.
-
Heavy Metal Limits:
-
Lead (Pb): ≤ 4 mg/kg
-
Arsenic (As): ≤ 3 mg/kg
-
Selenium (Se): ≤ 30 mg/kg
-
Assess Physical Characteristics
-
Appearance: Food grade manganese sulfate should be a consistent pale pink color, indicating good quality control .
-
Particle Size: Depending on your application—whether for direct compression in supplements or dissolution in liquids—you may require a specific mesh size (e.g., 30-60 mesh) to ensure flowability and mixing consistency .
Supplier Credibility and Packaging
Source from suppliers who specialize in food ingredients. Ensure that the manufacturing and storage facilities follow current FSSC22000 or ISO22000 . Proper packaging is also vital to maintain product integrity.
-
Packaging: Look for packaging designed to protect the product from moisture, such as plastic-lined bags or fiber drums. Common packaging sizes are 25kg bags or 50kg fiber drums .
-
Storage: The product should be stored in a dry, ventilated warehouse away from moisture and toxic substances .
