Food-grade dibasic potassium phosphate with stable chemical indicators. Chemical name is Potassium Phosphate Dibasic, molecular formula K₂HPO₄, molecular weight 174.18, CAS 7758-11-4, meeting international food-grade raw material standards.
Physical Properties
The product is colorless or white square crystal granules or powder with obvious deliquescence. It presents alkaline characteristics and is insoluble in ethanol. The 1% aqueous solution maintains a stable pH value of approximately 9, with reliable chemical stability for food processing.
Food Application
Widely used in the food industry as a buffering agent, chelating agent, yeast food, emulsifying salt and antioxidant synergistic agent, optimizing food system stability and product quality.
Packaging Specification
Standard 25kg double-layer protective packaging. Inner polyethylene sealed bag suppresses deliquescence, outer compound woven bag provides mechanical protection for logistics.
Storage & Transportation Requirements
Store in low-humidity, ventilated dry warehouses to reduce deliquescence. Keep away from heat and moisture during transportation. Handle packages gently. Strictly separate from toxic substances to ensure food-grade purity.
