Citric acid has a molecular formula of C6H8O7. It is an important organic acid. It is a colorless crystal, odorless, has a strong sour taste, and is easily soluble in water. It is an acidity regulator and a food additive.
Citric acid is the most biochemically produced organic acid in the world, and citric acid and its salts are one of the pillar products of the fermentation industry. Mainly used in the food industry, such as sour agent, solubilizer, buffer, antioxidant, fishy and deodorant agent, flavor enhancer, gelling agent, toner, etc.
Food-grade citric acid is primarily derived from natural, renewable raw materials such as corn or sugarcane, emphasizing its alignment with eco-friendly practices. The use of plant-based substrates not only ensures a sustainable supply chain but also supports the growing consumer demand for products with a reduced environmental footprint. By harnessing nature's resources in a responsible and efficient manner, the production process guarantees that food-grade citric acid remains a green choice for modern food manufacturers.
