tbl lemon juice

Lemon juice is the acidic liquid extracted from the fruit of Citrus limon, a small evergreen tree native to Southeast Asia and widely cultivated in Mediterranean climates. The juice comprises approximately 5-6% citric acid by weight, along with ascorbic acid (vitamin C), minerals, and aromatic compounds that give it its characteristic sharp, tart flavor. Fresh-squeezed lemon juice is cloudy and perishable, while commercial bottled versions may be clarified, concentrated, or preserved with sulfites. The primary acid content (primarily citric acid) is responsible for its fundamental role in both flavor development and food preservation.

Lemon juice exists in two primary forms: fresh juice from whole lemons and processed juice, which may be from concentrate or bottled with preservatives. The freshly squeezed product is prized for its bright, complex citrus notes and aromatic qualities, while concentrated juice offers convenience and extended shelf stability. The acidity, typically around pH 2-3, makes lemon juice a potent culinary agent that extends far beyond simple flavor addition.

Lemon juice functions as both a flavor enhancer and functional ingredient across global cuisines. It brightens dishes by adding acidity that balances richness and rounds out flavors—used in vinaigrettes, marinades, and finishing preparations. In preservation, its acidity prevents browning in produce and inhibits bacterial growth in ceviche and other acid-cured preparations. Lemon juice is essential in Mediterranean, Middle Eastern, and Asian cuisines, appearing in classics like Greek salads, Mexican ceviches, Indian curries, and cocktails. It is often applied at the last moment to preserve volatile aromatic compounds, though it also features in cooking and reduction for depth.
