What Elements Are in Lemon Juice?

Lemons are citrus fruits that grow in tropical locations, but they are shipped all over the world. Their juice is used in drinks, recipes and even cleaning supplies. Known as a sour fruit, the tart flavor of lemon juice is mixed with natural and artificial sweeteners to make lemonade and other drinks. The juice from the lemon is known to be low in calories and high in vitamin C, making it a popular and healthy option. Add this to my Recipe Box.

Lemon Flavor

    The most commonly recognized quality of lemon juice is its tartness. This results from a relatively high concentration of citric acid, which amounts to approximately 5% of its volume. Other acids in lemon juice include malic acid, ascorbic acid (also known as vitamin C, which is another important ingredient), tartaric acid, fumaric acid and trace amounts of other acids.
