Food grade phosphoric acid is an inexpensive sour agent that can replace citric acid for the production of various beverages. According to reports, beverages such as cola are made with dilute phosphoric acid as the main body, supplemented by various flavoring agents. Food-grade phosphoric acid is also the basic raw material for the production of food-grade phosphate. Starting from food-grade phosphoric acid, it can produce multiple series and varieties of food-grade phosphates. Phosphate can adjust and improve the structure, color, aroma and taste of the food in food, and improve the performance of food during baking. Phosphorus is also an indispensable basic nutrient element for the human body, so food-grade phosphoric acid and food-grade phosphate have long been widely used as food additives in developed countries.
China started late in the development and application of food-grade phosphoric acid and food-grade phosphate, but with the development of the national economy and the gradual improvement of people’s living standards, the country has also given sufficient attention to the development of food-grade phosphoric acid and food-grade phosphate. It has successively formulated national standards for food-grade phosphoric acid and some food-grade phosphates. Some domestic scientific research units and production plants are also developing and have achieved certain results. Food-grade phosphoric acid and food-grade phosphate have been used in the beverage industry and food canning industry. China is a country with a large population, and the potential market of food-grade phosphoric acid and food-grade phosphate is very large in China.
