Product use and characteristics:

In food industry---used as food additives, emulsifiers, texture improvers, chelating agents, quality improvers, alkaline aqueous agents for flour products raw material; it can prevent discoloration of canned fruits; improves the expansion of ice cream and the yield of ham and sausage; enhances the water-holding capacity of fish, improves the taste of noodles, increases yield, and prevents aging of cheese, etc.

For technical grade---TKPP can be used as water soluble fertilizer. It can be used for soil improvement, also it is a high-efficiency phosphorus and potassium compound fertilizer. Adding an appropriate amount of trace elements can make a multi-element efficient high-nutrient macroelement water-soluble fertilizer, which can be used by irrigation way. Tetrapotasssium Pyrophosphate aqueous solution, which can not be directly absorbed by crops because it contains the pyrophosphate , it shall be firstly converted into orthophosphate and then absorbed, so it has the effect of slow release, in addition, when the product is dissolved in water and it is an exothermic process, so this raises the temperature of the water so that frost damage to the crop roots is avoided.

Packaging and storage: inner plastic outer weaving, net weight 25, 1000Kg per bag or customized according to customers’ requirements. Store in a ventilated and dry place, avoid rain, humidity, handle with care, prevent bag damage, keep away from toxic substances.

Shelf life：24 months
