Fumaric Acid is commonly used as a food additive (European E-number E297). It is an acidulant and can impart a sour flavor. It is commonly used to give dry foods a vinegar-like flavor in products like salt-and-vinegar potato chips. It is also used in lamb feed and causes lambs to produce 70% less methane during digestion. Industrially, fumaric acid is in the production of dyes, polyhydric alcohols and polyester resins. It is produced by the catalytic isomerization of maleic acid which is derived from maleic anhydride (produced from benzene and butane).
