Food Grade Acetic acid (CAS 64-19-7) is used as a food additive in the form of vinegar, which is a dilute solution of acetic acid. It is commonly used for flavoring, preserving, and pickling foods.
What is Food Additive Acetic acid E260 ?
E260, more commonly known as acetic acid, plays a vital role in culinary processes and food preservation. It is a simple organic compound with the chemical formula CH₃COOH.
Acetic acid can be produced naturally or synthetically. Fermentation is used to produce vinegar. In this method, ethanol is oxidised by Acetobacter bacteria. Synthetic production involves a chemical reaction between methanol and carbon monoxide.

Food Grade Acetic acid Applications
| Function | Applications |
| Acidulant | As an acidulant, acetic acid helps maintain and adjust food products' pH, ensuring optimal conditions for taste, texture, and microbial stability. |
| Flavoring Agent | Acetic acid acts as a flavoring agent by imparting a distinctive sour or tangy taste to foods and beverages, enhancing their palatability. |
| Preservative (Antimicrobial Agent) | Due to its antimicrobial properties, acetic acid acts as a preservative, inhibiting the growth of harmful bacteria, yeasts, and molds, thereby prolonging the shelf-life of food products. |
| Flavor Enhancer | As a flavor enhancer, acetic acid boosts the existing flavors in food items, improving their sensory appeal. |
| Raising Agent | Acetic acid can act as a raising agent in the baking industry. It reacts with baking soda to produce carbon dioxide gas, resulting in a leavening effect that gives baked goods their fluffy and light texture. |
| Edible Food Coating Agent | When used as an edible food coating agent, acetic acid helps to preserve the freshness and extend the shelf life of fruits and vegetables by creating a protective layer. |
