About
Lemon juice is the acidic liquid extracted from lemons (Citrus limon), a small yellow citrus fruit native to Asia and widely cultivated in Mediterranean regions. The juice comprises approximately 5-6% citric acid by volume, which provides its characteristic sharp, tart flavor and significant food preservation properties. Fresh lemon juice is extracted by hand-squeezing or mechanical pressing of the fruit, yielding a clear to pale yellow liquid with a pH of approximately 2-3. The juice contains both soluble and volatile compounds that contribute complexity beyond simple acidity, including limonene and other aromatics that enhance the sensory profile of dishes.
Lemon juice is a fundamental acidifying agent in kitchens worldwide, essential for balancing flavors, brightening dishes, and preventing enzymatic browning in foods.
Culinary Uses
Lemon juice functions as a multipurpose acidifying agent in virtually all culinary traditions. In European cuisines, it brightens sauces, dressings, and seafood preparations; in Mediterranean cooking, it is central to vinaigrettes and marinades. Asian cuisines employ lemon juice in curries, stir-fries, and dipping sauces, while Latin American and Middle Eastern traditions use it in ceviches, salsa verde, and tahini-based sauces. Beyond flavor, lemon juice prevents oxidative browning in fruits and vegetables, cooks delicate proteins, and balances richness in fatty dishes. It is equally valuable in beverages, desserts, and preserves.
