Citrus limetta
Citrus limetta, commonly known as sweet lime, sweet lemon, and sometimes Mediterranean sweet lemon, is a species of citrus fruit from the family Rutaceae. It is closely related to the lemon and lime, but it has a sweeter and less acidic flavor. The fruit is consumed all over the world but is especially popular in South Asia, Southeast Asia, and some Mediterranean countries.
Description[edit | edit source]
Citrus limetta grows on small trees or bushy plants that reach a moderate height. The leaves are green, glossy, and aromatic. The flowers are white and can be quite fragrant, typical of citrus flowers. The fruit itself is round, typically 3–6 cm in diameter, and has a greenish-yellow to yellow color when ripe. The peel is thin, and the interior is divided into segments filled with juicy vesicles. Unlike its citrus cousins, the sweet lime has very little acidity and a sweet flavor, making it unique among citrus fruits.
Cultivation[edit | edit source]
Sweet lime is cultivated in tropical and subtropical climates. It requires well-drained soil and full sun exposure. The trees are frost-sensitive and need protection from cold weather. They are propagated through grafting to ensure fruit quality and disease resistance. Major producers include India, Mexico, and Egypt.
Uses[edit | edit source]
The fruit of Citrus limetta is primarily consumed fresh. Its juice is highly valued for its sweet flavor and is often used in beverages, desserts, and as a flavoring agent in various dishes. In traditional medicine, sweet lime juice is recommended for its digestive benefits and is believed to have a cooling effect on the body. The peel and essential oils extracted from the fruit are used in the cosmetic industry and for household cleaning products due to their pleasant scent and antibacterial properties.
Nutritional Value[edit | edit source]
Sweet lime is rich in Vitamin C and dietary fiber. It also contains various antioxidants and minerals such as potassium, which are beneficial for health. The fruit is low in calories, making it a popular choice for those looking to maintain a healthy diet.
