Perfume and Flavor Chemicals, page 272.
Colorless liquid.
Insoluble in water, soluble in alcohol, miscible with most perfume and flavor oils.
Widely used as a powerful lemon-fragrance chemical, but suffers from poor stability in many types of functional products.
Very commonly used in flavor compositions. Used in imitation apple, cherry, ginger, grape, lemon, lime, orange, grapefruit, spice, strawberry and even in vanilla.
Accordingly, its use is somewhat restricted and there is a low limit of concentration of Citral for most perfumes.
Concentration is normally about 40 ppm in the finished product, but can be up to 150-170 ppm in chewing gum.
