Typical source

Fermentation or synthetic

Plain-language explanation

Acetic acid, also known as E260, is the main compound that gives vinegar its sour taste and is used as a preservative and flavoring. It can be produced naturally through the fermentation of ethanol by bacteria, which is always considered halal, or it can be synthetically made from non-halal sources like petroleum. Major halal certification bodies consider acetic acid halal when it is derived from plant-based fermentation, but its status depends on the source if it is synthetically produced.
