Sodium tripolyphosphate is generally added 3-5‰ in food processing, and the maximum amount is 3% in aquatic processing.
Properties: White powder with a melting point of 622°C, readily soluble in water, exhibiting significant chelation ability towards calcium and magnesium metal ions. It can soften hard water, transform suspensions into solutions, has weak alkalinity, and is non-corrosive. As an inorganic surfactant, it demonstrates strong emulsifying properties for lubricating oils and fats. The bulk density is typically categorized as low (0.35-0.5 g/cm³), medium (0.51-0.65 g/cm³), or high (0.66-0.9 g/cm³).
