About
Lemon juice is the acidic liquid extracted from lemon fruits (Citrus limon), a small, oval citrus native to Southeast Asia and now cultivated worldwide in temperate and subtropical climates. The juice comprises approximately 5-6% citric acid, along with ascorbic acid (vitamin C), sugars, and various flavor compounds that provide its characteristic tart, bright taste. Fresh-squeezed lemon juice is prized for its vibrant acidity and aromatic quality, while bottled and concentrate forms offer convenience with varying degrees of flavor intensity.
The primary juice-bearing varieties include Eureka, Lisbon, and Meyer lemons, each with slight variations in acidity and sweetness. Meyer lemons, a cross between lemon and mandarin orange, are notably less acidic and slightly sweeter than standard varieties.
Culinary Uses
Lemon juice functions as one of the most versatile culinary ingredients, serving simultaneously as an acid, flavor enhancer, and preservative. In its simplest form—a few drops—it brightens dishes by cutting richness, balancing salt and sugar, and preventing enzymatic browning in fruits and vegetables. It is essential to marinades, vinaigrettes, and emulsions (particularly mayonnaise and hollandaise); fundamental to Asian, Mediterranean, and Latin American cuisines; and indispensable in seafood preparations, where its acidity partially "cooks" raw fish in ceviches. Beyond savory applications, lemon juice sweetens beverages, extends shelf life, and intensifies flavors in desserts and preserves.
