Why this verdict

E336 is potassium tartrate (cream of tartar), used in baking powder, meringues, and confectionery. SANHA classifies E336 as Mushbooh because tartaric acid is commonly recovered as a by-product of winemaking. JAKIM Handbook 2010 classifies E336 as halal when it is not obtained from a wine by-product. MUIS marks E336 as syubhah, listing it plainly as a by-product of the wine industry. Because the source is not always disclosed on the label, E336 is doubtful by default.
