Potassium dihydrogen phosphate market
1. Market overview
The potassium dihydrogen phosphate industry market has shown a steady growth trend in recent years.
In 2023, the global potassium dihydrogen phosphate market capacity reached 14.924 billion yuan,
and is expected to grow at an average annual growth rate of 2.8% to 17.729 billion yuan by 2029.
As one of the important producers of potassium dihydrogen phosphate in the world,
China occupies nearly 30% of the global market share,
and the domestic market size will be about 5.223 billion yuan in 2023.
2. Main application areas
The application of potassium dihydrogen phosphate in the industrial market mainly includes the following aspects:
Food industry: As a food additive, potassium dihydrogen phosphate is used to regulate the pH of food,
improve taste and extend shelf life, and is widely used in bread, pastries, beverages and meat products.
Agriculture: As a highly efficient water-soluble fertilizer, potassium dihydrogen phosphate provides phosphorus
and potassium required by plants to promote crop growth, improve yield and quality.
