To truly appreciate the scent of lychee, it is important to understand the fruit itself. Lychee, scientifically known as Litchi chinensis, is a monotypic tree in the soapberry family, Sapindaceae [2]. It is native to South China, Malaysia, and northern Vietnam and is widely cultivated in Southeast Asia and South Asia. The lychee tree is evergreen, reaching heights of up to 15 meters, and its leaves are pinnate with 4 to 8 elliptic-oblong leaflets. The flowers grow in clusters and possess a fragrant aroma, which is a precursor to the enticing scent of the fruit itself.

The lychee fruit is small, sweet, and enclosed within a pink-red, rough-textured outer shell. It has a fleshy texture, varying in shape and size, and a thin, easily removable skin that reveals the delicious fruit inside. The sweet, aromatic aril, which is the edible part of the fruit, is where the enticing fragrance of lychee originates. The seeds of lychee contain methylene cyclopropyl glycine, which has been linked to hypoglycemia and encephalopathy in malnourished children who consumed the fruit [2]. Therefore, it is important to enjoy lychee responsibly and focus on its delightful aroma and flavor.

Lychee cultivation dates back to ancient China, where it was highly regarded and even enjoyed in the Chinese Imperial Court. The fruit gained attention from European travelers and was introduced to the West in the 17th century. Since then, it has become a beloved tropical fruit globally, celebrated for its unique taste, texture, and, of course, its enchanting scent. Lychee thrives in frost-free climates with high heat, rainfall, and humidity, making it an ideal crop in various tropical regions [2].

The Scent Profile of Lychee

The aroma of lychee is often described as aqueous, rosy, and mildly sweet, resembling the scent of juicy grapes [1]. It is a captivating fragrance that combines floral and fruity notes, creating a unique olfactory experience. Various molecules present in lychee contribute to its scent profile. Let's explore some of these key compounds [1]:

• Guiacol: This aromatic compound is responsible for the smoky and phenolic notes in lychee's fragrance.
• Vanillin: Known for its sweet and creamy scent, vanillin adds a touch of warmth and richness to the aroma.
• Furaneol: This molecule imparts a sweet, caramel-like note to lychee, enhancing its overall sweetness.
• b-damascenone: With its floral character, b-damascenone adds a rosy facet to the scent of lychee.
• Cis-rose oxide: This compound contributes to the floral and rose-like aroma of lychee.
• Linalool: Linalool is a versatile molecule found in many flowers, including lychee. It imparts a fresh and floral scent.
• Isovaleric acid: This compound provides a slightly cheesy note, contributing to the complexity of lychee's fragrance.
• Geraniol: Geraniol, with its sweet and rosy scent, adds a delicate floral nuance to lychee.

These aromatic molecules work together to create the distinct scent of lychee. Although lychees cannot be distilled like most fruits, their fragrance has been successfully incorporated into perfumery through synthetic production. Perfumers often utilize lychee to provide a fresh, watery tone to floral compositions or to add a hint of fruitiness to floriental fragrances. The combination of lychee with honey and rose can result in delicate and graceful fragrances [1]. Many fragrance brands, both niche and designer, have embraced lychee as a captivating scent. Perfumes from renowned brands such as Laura Biagiotti, Coco Mademoiselle, Benefit, Juliette has a Gun, Chopard, Dolce & Gabbana, Emporio Armani, Estée Lauder, Lancôme, Guerlain, and Calvin Klein feature lychee notes in their creations [1].
