Description and Uses
Trans-2-octenoic acid has found a little use in perfumery as a trace ingredient in artificial essential oils, etc. It has been suggested for use in flavor compositions, but at this time (Oct. 1968) it has not yet been listed as G.R.A.S. by the American authorities. It could probably be used in imitation Cheese, Butter, Nut, Butterscotch compositions, etc.
