Bulk Magnesium Gluconate Powder Supplier|High-purity magnesium gluconate for dietary supplements, functional foods, beverages, and pharmaceutical applications. ISO9001-certified factory with OEM support and global export capability.
Magnesium Gluconate Powder is an organic magnesium salt produced through the reaction of magnesium compounds with gluconic acid. Gluconic acid is commonly obtained through the fermentation of glucose using food-grade microorganisms, followed by purification and mineral salt formation. It is commonly used as a highly soluble magnesium ingredient in supplements and functional foods.
Raw Material Preparation
Food-grade magnesium sources and fermentation-derived gluconic acid are carefully selected and tested.
Neutralization Reaction
Magnesium compounds react with gluconic acid under controlled temperature and pH conditions to produce magnesium gluconate.
Purification
The solution undergoes filtration, purification, and concentration to remove impurities.
Crystallization
Controlled crystallization forms stable magnesium gluconate crystals.
Drying
The crystals are dried using controlled drying technology to achieve low moisture content.
Milling & Sieving
The dried material is milled into a uniform powder with controlled particle size.
