Chemical Information
FooDB NameAcetic acid
DescriptionHas been used as a food preservative since antiquity. It is used in - and contributes to - the flavour of pickles, sauces, mayonnaise and salad dressings. Acts synergistically with lactic and sorbic acid, and is more effective against yeasts and bacteria than against moulds. It is used in food processing as a flavour enhancer, flavouring agent, pH control agent, pickling agent, solvent and formulation aid Acetic acid is an organic compound with the chemical formula CH3COOH. It is a colourless liquid that when undiluted is also called glacial acetic acid. As the main component of vinegar, it has a distinctive sour taste and pungent smell. Acetic acid is found in many foods, some of which are garden rhubarb, wild celery, pear, and ginger.
