Trisodium Phosphate
Usage: In food processing industry, it is used as buffering agent, emulsifier, anti-caking agent, antioxidant additive, nutrition supplement and metal chelating agent.
Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
