Konjac root

Plain-language explanation

E425, commonly known as konjac, is a natural food additive derived from the root of the konjac plant, which is native to parts of Asia. It is primarily used as a thickening agent, gelling agent, or dietary fiber in various food products like noodles and jellies. Because it is entirely plant-based, it is universally considered halal by all major certification bodies, including JAKIM, MUI, MUIS, ESMA, and HFA. You can safely consume products containing this ingredient without worrying about animal-derived contamination, though it is always good practice to ensure the overall product carries a reliable halal certification.
