Food safety has always been one of the focus areas of consumer concern. As the manufacturer of sodium hexametaphosphate, we think that the safety of food additives is also a top priority.

Choosing sodium hexametaphosphate should start with the manufacturer. The credit of the manufacturer who specializes in producing phosphate, such as Chongqing Chuandong Chemical, is very good. Sixty-four years of research and development of production technology, but also with the relevant qualifications of food grade production, so that sodium hexametaphosphate in food applications more widely.

Secondly, the production of food grade sodium hexametaphosphate must be based on food grade phosphoric acid and soda by thermal method. Because wet-process phosphoric acid can not achieve the quality of food grade production, because in the preparation method, the thermal process is yellow phosphorus furnace to produce yellow phosphorus, and then burning water to absorb into phosphoric acid. The wet process is to decompose the ore powder with sulfuric acid to obtain phosphoric acid. The difference between the main components is that the thermal method contains fewer impurity ions and the wet method contains more impurity ions, which can not reach the food grade quality.

The main functions of food grade sodium hexametaphosphate in food are water retention agent, acidity regulator, stabilizer, bulking agent, anticoagulant and coagulant. However, there is a clear stipulation on the amount of food additions, the maximum amount of additions is 10g/kg. In addition, the content of fluorine, lead, arsenic and other ions in the products is also clearly required (one in a million). To ensure the production of edible food grade sodium hexametaphosphate, factories need relevant qualifications. Chongqing Chuandong Chemical also reminds buyers here to buy products from qualified manufacturers, so that heavy metals and impurities indicators can meet the use requirements.
