Application
Citric acid give food a strong and refreshing sour taste and improve the taste and flavor of food.
Preservatives can inhibit the growth and reproduction of microorganisms and extend the shelf life of food.
Buffers adjust the pH value of the food system to maintain the stability of food.
Complexing agents combine with metal ions to prevent metal ions from having adverse effects on food quality.
