Bacterial fermentation

Plain-language explanation

Gellan gum is a thickening agent produced by fermenting sugar with the bacterium Sphingomonas elodea. It is considered halal by major certification bodies like JAKIM, MUI, MUIS, ESMA, and HFA, as the fermentation process is permissible. However, its halal status depends on the source of the sugar used in production, which must be from halal-certified ingredients and free from alcohol or non-halal enzymes.
