Abstract: A method of producing a potent epoxydecenal flavorant. Trans-4,5-epoxy-(E)-2-decenal is enriched to contain at least 90% of the (−) isomer and is added to a product in an amount sufficient to flavor the product. The product may be a foodstuff, such as a food or beverage. Addition of the substantially pure (−)-trans-4,5-epoxy-(E)-2-decenal isomeric form achieves enhanced product taste and/or aroma, and provides increased economy and efficiency in its production.
