Food Grade Phosphoric Acid Uses

Food-grade phosphoric acid can be used as a flavoring agent; it can be used as a sour agent in cans, liquids, solid beverages and refreshing drinks, and can replace lemon and malic acid; in the beer saccharification process, it can replace lactic acid to adjust the pH value; in the sugar industry, it can be used as sucrose Clarifying agent; used in brewing as a yeast nutrient to prevent the reproduction of miscellaneous bacteria; flour is used as a improver, and is also widely used in high-precision electronics industry, pharmaceutical industry, etc.

The production methods for producing food-grade phosphoric acid mainly include thermal process and wet process: The thermal process uses phosphosilica, ore, coke, etc. as raw materials to reduce the phosphorus substances contained in the phosphate rock into phosphorus elements, and then convert the yellow phosphorus into It is burned in the air to produce phosphorus pentoxide, and finally the phosphorus pentoxide and water are reacted to produce phosphoric acid, which is called thermal phosphoric acid; the wet process uses strong inorganic acid to decompose the phosphate rock, and then filters the slurry The crude phosphoric acid is separated and purified (extraction, washing, distillation, decolorization, concentration, defluorination, bleaching and other processes) to produce phosphoric acid, which is called wet phosphoric acid. The phosphoric acid produced by the thermal phosphoric acid production process has good quality and high concentration. However, due to factors such as high energy consumption, high cost, and the production of chemical books accompanied by dust and toxic gases during production, its application proportion in the world is gradually declining.

 There is a downward trend; compared with the thermal phosphoric acid process, the production cost of the wet phosphoric acid process can be reduced by 20% to 30%, and the energy consumption is reduced by 2/3. After the purification process, the product quality is even better than that of the thermal phosphoric acid, especially the specific heat of heavy metal content. French phosphoric acid is low and is currently mainly used in industries such as metal surface treatment and phosphate preparation. The food industry mainly uses thermal phosphoric acid, and recognition of wet phosphoric acid is low. Now, food-grade wet-process phosphoric acid is used as the object to study its role as a degumming agent in vegetable oil degumming, and the degumming effect is compared with food-grade thermal phosphoric acid, aiming to provide scientific information for the application of food-grade wet-process phosphoric acid in the vegetable oil degumming process. in accordance with.
