Bacterial fermentation

Plain-language explanation

E418, or gellan gum, is a thickening agent produced by the bacteria Sphingomonas elodea through a fermentation process. Since it is created from microbial fermentation and not from animal sources, it is universally considered halal by major certification bodies like JAKIM, MUI, and MUIS. Its halal status is not dependent on the source, provided the growth medium used for the bacteria does not contain any haram or doubtful ingredients. Therefore, it is generally regarded as a safe and permissible ingredient for Muslim consumers.
