Lemon juice, that tangy and refreshing liquid, is a staple in kitchens and bars around the world. But beyond its obvious sourness, what exactly is in lemon juice? Let’s dive into the world of lemons and explore the components that make this juice so special.
The Basics: Water and Carbohydrates
Like many fruits, lemons are primarily composed of water. Water makes up about 88-89% of lemon juice, making it a hydrating choice. The remaining portion consists mainly of carbohydrates, about 10%. A medium-sized lemon contains only around 20 calories, making it a guilt-free addition to your diet.
The Star Player: Citric Acid
The characteristic sour taste of lemon juice comes from citric acid. Lemon juice typically contains 5-6% citric acid. This natural acid is responsible for many of the culinary uses of lemon juice, from flavoring dishes to acting as a preservative.
- Quantity: Lemon juice contains 1.44 grams of citric acid per ounce. Lemon juice concentrates contain 1.10 grams of citric acid per ounce.
Vitamins and Minerals
Lemons are well-known for being a good source of vitamin C. Vitamin C, also known as ascorbic acid, is an essential nutrient and antioxidant. A 100g serving of lemons provides 64% of the daily recommended value of Vitamin C.
Lemons also contain small amounts of minerals. These include:
- Calcium
- Potassium
- Magnesium
- Iron
- Sodium
Other Organic Compounds
Besides citric acid and Vitamin C, lemon juice contains various other organic compounds that contribute to its flavor and aroma. These include:
- Alkaloids
- Flavonoids
- Phenolic compounds
- Reducing sugar
- Terpenes
- Glycosides
- Tannins
- Saponins
Lemon Juice and Acetic Acid
To stabilize lemon juice, acetic acid vinegar is sometimes added. A lemon juice composition should have at least 25% acetic acid vinegar, and can be as high as 75%. A composition of 25–50% vinegar, containing 4.5–6% acetic acid, is typically preferred for commercial purposes. The acetic acid vinegars that are suitable for use include cider, malt, Taragon, Rexamber, and White Distilled.
The Importance of Balance
The components of lemon juice work together to create its unique properties. The citric acid provides the sourness, while the other organic compounds contribute to the aroma and complexity of flavor. The vitamins and minerals offer nutritional benefits.
Lemon Juice in the Culinary World
In cooking, lemon juice is a versatile ingredient. Just a few drops can enhance the flavor of a dish. Lemon juice is a key ingredient in drinks like lemonade, and desserts like lemon meringue pie. It can also prevent fruit from browning.
