no: lemon juice
Lemon juice is a good source of vitamin C and citric acid, with minimal calories and no significant fat or protein content. It contains trace amounts of potassium and antioxidant compounds including flavonoids.
About
Lemon juice is the acidic liquid extracted from the fruit of Citrus limon, a small evergreen tree native to Southeast Asia. The juice comprises approximately 5–6% citric acid by weight, along with water, sugars, and trace minerals, giving it a distinctly sour and tart flavor profile. Fresh lemon juice appears pale yellow to clear, while bottled versions may contain preservatives. The juice's acidity and flavor intensity vary depending on fruit ripeness, growing conditions, and storage duration. Commercially, lemon juice is produced through mechanical pressing and often pasteurized for shelf stability.
Culinary Uses
Lemon juice serves as both a flavoring agent and functional ingredient across global cuisines. It brightens dishes by adding acidity without salt, making it essential in vinaigrettes, marinades, sauces (hollandaise, béarnaise), and seafood preparations. The juice prevents oxidation in fruits and vegetables, inhibits bacterial growth in ceviche, and tenderizes proteins through acid denaturation. It is fundamental to Mediterranean, Middle Eastern, and Asian cooking, appearing in everything from Greek avgolémono soup to Indian curries and Asian stir-fries. Fresh-squeezed juice offers superior flavor and aroma compared to bottled versions, though the latter provides convenience and consistency.
