Recently, the shortage of spot goods has intensified, which has entangled downstream manufacturers who want to purchase recently. Either they have not found a suitable manufacturer, or the price is not too expensive. Sodium tripolyphosphate, as a basic chemical material and related phosphorus containing products, plays an important role, and the relative price has also increased. Why is the unit price of food grade sodium tripolyphosphate higher than that of industrial grade?

First of all, it can be seen literally that the content and related indicators of industrial grade sodium tripolyphosphate meet the national standard. The main raw material of sodium tripolyphosphate is phosphate rock. In the production process, the price of wet process is slightly lower, while the sodium tripolyphosphate produced by thermal process is relatively higher.

The raw material of food grade sodium tripolyphosphate is based on the thermal process. As a food additive, it is standardized and standardized in food processing. The production of food grade sodium tripolyphosphate ensures safety in the long process from raw material production to transportation to sales to consumption.

The industrial application of sodium tripolyphosphate has the functions of chelation, suspension, evacuation, gelling, emulsification and pH buffer. It can be used as an important assistant for synthetic detergent, industrial water softener, tanning pretanning agent, dyeing assistant, organic synthetic catalyst, evacuation agent for pharmaceutical industry, etc. Sodium tripolyphosphate of Chuandong Chemical Group plays an important role in ceramic production.

Food safety is a major event. As food additive, sodium tripolyphosphate can also be used in milk and dairy products, frozen drinks, nuts, cocoa and chocolate products, wheat flour and its products, cooked meat products, baked food, expanded food, canned aquatic products, etc.

It can be seen that there is an essential difference between industrial grade and food grade sodium tripolyphosphate. Food grade can be used for industrial purposes, while industrial grade sodium tripolyphosphate must not be used for food purposes. Because there are no requirements for heavy metals such as arsenic and lead in the industrial grade product indicators, the unit price of food grade sodium tripolyphosphate is higher than that of industrial grade.
