Sodium Tripolyphosphate
Usage: Used as organizational improvement agent, pH buffer, removal of metal ions, for meat processing, processing of aquatic products, meat products and dairy processing water treating agent and so on. In the processing of meat, aquatic products processing, flour products as a texture modifier, with an increase in the effect of water retention in food.
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.
