Application
Citric acid provide sourness to food, adjust the taste of food and make it more delicious. Antioxidants can inhibit oxidation reactions in food and extend the shelf life of food.
Chelating agents can bind to metal ions to prevent food deterioration and color changes caused by metal ions.
Promote gelation and help form gel structure in certain food processing.
Regulate PH value to adjust the acidity and alkalinity of food to meet the needs of processing and preservation.
