Acidity regulators

Acidity regulators help to maintain a constant acid level in food. It alter or controls the acidity or alkalinity of a food.

This is important for taste, as well as influencing the function of other substance in the food. Food acids are included in foods to accomplish a number of tasks including sharpening the flavors as well as perform the function of preservatives and antioxidants.

An acidified food can retard the growth of some micro-organisms.

Food acids used most frequently for these purposes included acetic cid, citric acid, tartaric acid, malic acid, fumaric acid and lactic acid.

pH considerations are important in packaged foods and beverages. Excessively acidic or alkaline conditions can alter the appearance, taste and nutrient quality of prepared foods and beverages.

Example include citric acid and various forms of phosphate like sodium dihydrogen phosphate in soft drinks.
