Analytical Methods and Phytochemistry of the Typical Italian Liquor "Limoncello": A Review

Abstract

Following an ancient tradition, limoncello is a homemade liqueur obtained from peels of Sorrento lemons. However nowadays, due to the fact that its production on industrial scale is widespread and the demand on the international market is increasing, virtually all kinds of lemons are used to make this liqueur. Its main distinctive feature is a bright yellow colour. Limoncello is served especially after-dinner as a digestive after having been stored in a refrigerator at 4 °C. It is very popular and commonly consumed in all Italy and many areas of the Mediterranean region but it is also becoming famous in other countries like United States, Canada, Australia, New Zealand, and northern Europe.
