About
Lemon juice is the acidic liquid extracted from lemons (Citrus limon), a citrus fruit native to Asia Minor and widely cultivated in Mediterranean regions. The juice comprises approximately 5-6% citric acid, along with ascorbic acid (vitamin C), flavonoids, and volatile aromatic compounds that give lemons their characteristic sharp, tart flavor. Fresh lemon juice has a bright, clean acidity and subtle floral undertones, while bottled and pasteurized versions may have slightly altered flavor profiles due to processing. The juice's pH typically ranges from 2.0 to 3.0, making it highly acidic.
Culinary Uses
Lemon juice functions as both an acidulant and flavor enhancer across global cuisines. It is essential in Mediterranean, Middle Eastern, and Southeast Asian cooking, used to brighten seafood dishes, emulsify vinaigrettes, and prevent enzymatic browning in cut fruits and vegetables. The juice serves as a key ingredient in marinades, dressings, sauces (such as hollandaise and beurre blanc), and beverages from cocktails to lemonades. In baking, it activates baking soda and provides acidity to balance sweetness. The juice is also used as a primary ingredient in pickling, curing, and food preservation.
