产品参数：

Product Name: Tetra Potassium Pyrophosphate (TKPP) Food Grade

Chemical Formula: K₄P₂O₇

Molecular Weight: 330.34
CAS NO.: 7320-34-5
National Standard: GB 25562-2010

产品说明

Properties: Solid particle potassium pyrophosphate is a white powder with a relative density of 2.534 and a melting point of 1109 ℃. It is easy to absorb moisture and deliquesce. It is easy to dissolve in water and insoluble in ethanol. At 25 ℃, 187 g of potassium pyrophosphate is dissolved in 100 g of water. It can chelate with alkaline earth metals and heavy metal ions.

Usage: In the food industry, it is used as an emulsifier, tissue improver, chelating agent, and also as a raw material of alkaline water for flour products. It is used with other condensed phosphates. Generally, prevent the occurrence of guano stone in canned aquatic products and prevent the discoloration of canned fruits; Improve the expansion of ice cream; Improve the yield of ham and sausage and the water retention of surimi; Improve the taste of noodles and increase the yield to prevent cheese aging. Added amount in food processing: processed cheese is 9g / kg (calculated by phosphorus); Lunch meat is 3G / kg (calculated by P2O5); The quick frozen shrimp is 5g / kg (calculated as P2O5).

Packing: The conventional packaging is 25kg / bag, double-layer plastic inner bag, and the outer bag is plastic woven bag.
Customized packaging and shipping marks.
