Potassium pyrophosphate, also known as tetra-sodium pyrophosphate, is made from the melting of di-potassium phosphate which causing it loss of one water molecule.
At room temperature, it is as a white crystalline powder or granules and has a strong moisture absorption capability in air and is easily soluble in water but insoluble in ethanol.
Its aqueous solution is alkaline and has effect on inhibition of food spoilage and fermentation.
The pH of 1% aqueous solution is about 10.5. At about 25 ºC, the solubility of potassium pyrophosphate in 100g of water is 187g.
It is hydrolyzed into potassium phosphate in acid or alkaline solution and can form a viscous-like slurry body when being mixed with water.
In the food industry, it is used as an emulsifier, chelating agent, tissue improvement agent, etc.
It is mostly used in combination with other condensed phosphates, such as for the preparation of adhesive of ham and sausage in the ratio of 10% potassium pyrophosphate, 10% sodium pyrophosphate, 30% potassium polyphosphate, 30% sodium polyphosphate and 20% sodium metaphosphate.
It is commonly used for preventing the generation of struvite in canned fish, preventing the discoloration of canned fruit, increasing the swelling degree of ice cream, the extracting amount of the raw materials of coffee as well as the yield of ham and sausage, enhancing the water holding capacity of fish, improving the taste and yield of noodles, and preventing the aging of cheese.
