Chemical Information
Name(E)-Aconitic acid
DescriptionIsolated from Asarum europaeum, from cane-sugar molasses, roasted chicory root, roasted malt barley, passion fruit, sorghum root and sugar beet. Flavouring agent used in fruit flavours and alcoholic beverages. Aconitic acid is an organic acid. The two isomers are cis-aconitic acid and trans-aconitic acid. The conjugate base of cis-aconitic acid, cis-aconitate is an intermediate in the isomerisation of citrate to isocitrate in the citric acid cycle. It is acted upon by aconitase. Trans-aconitate in the urine is a biomarker for the consumption of soy products. (E)-Aconitic acid is found in many foods, some of which are cereals and cereal products, rice, garden tomato (variety), and root vegetables.
