Something about food grade phosphoric acid

Food grade phosphoric acid is an inexpensive sour agents, it can replace citric acid used in the production of various beverages. Food phosphoric acid is the basic raw material of production of food-grade phosphates, food phosphoric acid can produce multi-series, multi-species food-grade phosphates. Phosphate in food can adjust and improve structure, color, flavor and sensory characteristics of the food, as well as improve performance in making baking food. Phosphorus is indispensable basic nutrients for the human, food grade phosphoric acid and phosphate for food in developed countries has been widely used as a food additive.

There are some difference between food grade phosphoric acid and CP grade phosphoric acid. Food phosphoric acid cannot have impurities to effect food safety, but it is not strict to purity; CP level of purity is required, namely, phosphoric acid content to meet the requirements of chemically pure. phosphoric acid or orthophosphoric acid is a common inorganic acid. Phosphoric acid in the air easily deliquescence. When heat it will water loss to get pyrophosphate, and further loss to get metaphosphoric acid. Phosphoric acid is mainly used for pharmaceutical industry, foodstuff industry, fertilizer industry, it can also be used as a chemical reagent.

Food grade phosphoric acid is considered from food safety, it distinguishes from other industrial products, such as food grade alcohol, food grade lubricants, food-grade wax, the request is it can not pollute the product or introduce new hazards when in use. China in development and application of food level phosphate and the food level  phosphoric acid aspects is more late, but with the national development, gradually improvement of living, our country pay more attention to food grade phosphoric acid and food level phosphate, and the national standards of them are established. Some domestic research units and production factory also develop it and certain results have been achieved. Food phosphates and phosphoric acid have been applied to the drink industry and  food canning industry. China is a populous country, food phosphoric acid and food-grade phosphates has a big potential in our market. Food grade phosphoric acid is also now have a certain market at present.
