Lemon Oil Argentina is cold-pressed from the peels of Citrus limon fruits, better known as the common lemon. The tree likely has its origins in northeast India, though it was eventually introduced to the Americas after Spanish explorers brought citrus seeds to New World colonies. The aroma of lemon oil is light and fresh, with a sweet and fruity odor highly reminiscent of fresh lemon peels. In perfumery, it is often used for its “refreshing” qualities, making it a common inclusion in lotions, creams, colognes, and various air care products. The flavor of lemon oil is similar to its aroma, exhibiting a refreshingly fruity and aldehydic tinge that goes well in candies, soft drinks, and countless other packaged goods. When blended with vanilla notes, lemon oil produces an old-fashioned “custard” flavor that is also highly appealing in frozen treats.
