Physical Properties

The product is a uniform white powder with excellent water solubility. It has a melting point of 622℃ and presents weak alkalinity with no corrosiveness. It possesses strong chelating activity for calcium, magnesium and other metal ions, enabling effective hard water softening and suspension dissolution. It acts as an inorganic surfactant and high-efficiency emulsifier for lubricants and fats. Bulk density ranges include 0.35-0.5g/cm³ (low density), 0.51-0.65g/cm³ (medium density) and 0.66-0.9g/cm³ (high density) for customized production.

Application Scope

Mainly used as a food quality improver for canned food, fruit juice beverages, dairy products and soybean milk. It tenderizes meat texture in canned ham and softens broad bean skin in canned bean products. It also serves as a professional softener and densifier for multiple food processing workflows in the food industry.

Packaging Specification

Adopt double-layer protective packaging. Inner polyethylene bag isolates external moisture and impurities, outer high-strength woven bag resists mechanical damage. Standard net weight per package is 25kg, meeting international bulk shipment standards.

Storage & Transportation Requirements

Preserve in dry and ventilated warehouse environments. Avoid exposure to high temperature and humid air during transportation. Conduct gentle loading and unloading operations to prevent package rupture and product loss.

Furthermore, it must be stored separately from poisonous substances.
