character
White powder or lump. The relative density was 2.534. Melting point 1109 ℃. Soluble in water, insoluble in ethanol. The aqueous solution is alkaline. The solubility of 100g water is 187 g at 25 ℃. The pH value of 1% aqueous solution was 10.2. Potassium pyrophosphate has all the properties of other condensed phosphates.
purpose
Emulsifiers, tissue improvers, chelating agents are used in food industry. They are also used as raw materials for preparing alkaline water for pasta products. They are usually used in combination with other condensed phosphates. They are usually used to prevent struvite in canned aquatic products, prevent discoloration of canned fruits, increase the expansion of ice, yield of ham and sausage, water holding capacity of ground fish, sending out flour taste and increasing yield, and preventing drying Aging of cheese, etc.
packaging and storage
25kg, 50kg, 1000kg, inner plastic and outer woven bags. Store in a well ventilated, dry and clean place.
