Additives are used for many purposes but the main uses are: Acids Food acids are added to make flavors "sharper", and also act as preservatives and antioxidants. Common food acids include vinegar, citric acid, tartaric acid, malic acid, folic acid, fumaric acid, and lactic acid.
Threshold in a food is dependent upon: The threshold of the aroma in air. Concentration in the food. Solubility in oil and water. Partition coefficient between the air and the food. The pH of the food. Some aroma compounds are affected by the pH: weak organic acids are protonated at low pH making them less soluble and hence more volatile.
Sodium benzoate can act as a food preservative. It is most widely used in acidic foods such as salad dressings (for example acetic acid in vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (acetic acid), condiments, and frozen yogurt toppings.
