Is Potassium Tartrate (E336) Halal?

MUIS lists E336 (Potassium Tartrate / Potassium Hydrogen Tartrate) as doubtful (mashbooh), which means the source cannot be confirmed from the E-number alone — not that it is haram. Although the base material is plant-derived, some production routes use animal-derived processing aids or carriers, and the E-number does not identify the producer. The reliable check is a recognised halal certification logo on the finished product, or a manufacturer statement of the source.

Potassium tartrate (cream of tartar) is the potassium salt of tartaric acid, recovered as a by-product of winemaking. It is widely used as a leavening acid in baking powder and to stabilise beaten egg whites.

• Look for a recognised halal certification logo (MUIS, JAKIM, MUI, HMC or similar) on the packaging — certified products have had the source of this additive verified.
• Check whether the label states the origin, for example 'vegetable origin', 'plant-based' or 'soy'.
• If there is no certification and the origin is not stated, contact the manufacturer or choose a product with a halal alternative.
