Lemon

Lemon (Citrus limon) is a small, oval or elliptical citrus fruit known for its vibrant yellow skin and tart flavor. Typically measuring between 6-12 cm in length and 4-7 cm in diameter, lemons have a smooth, slightly dimpled skin that may be green when unripe, turning bright yellow as it matures. The skin is relatively thin, about 1-3 mm in thickness, and contains essential oils that contribute to the fruit's characteristic scent and taste. Inside, the pulp is bright yellow, juicy, and segmented, with each segment containing 6-8 small, oval seeds. The fruit's primary taste is sour and acidic, with a pH level ranging between 2.00 and 2.60, though ripe lemons can also have a subtle sweetness. Lemons are highly valued for their acidity, which is commonly used in culinary applications, beverages, and as a natural preservative. The fruit's shelf life is typically 1-2 weeks at room temperature, but refrigeration can extend it to 3-4 weeks. Rich in vitamin C, lemons are widely used not only for their taste and health benefits but also for their essential oils, which are utilized in aromatherapy and cleaning products.
