Lemons belong to the Rutaceae, commonly known as the rue or citrus family. Lemons grown on an evergreen tree with sharp thorns on its twigs. Most citrus trees bloom and bear fruit only once a year. On the other hand, lemon trees bloom and give fruit all year round. Therefore, a lemon tree can flower, and at the same time, bear both unripen and ripened fruit.
Lemons taste extremely sour. It’s no wonder, because in their delicate yellow flesh are many fruit acids, especially citric acid and ascorbic acid – the latter is better known as vitamin C. Four lemons cover the daily vitamin C requirement, even though there are other fruits that are richer in vitamin C and much more pleasant to eat (40 g of blackcurrants cover the daily vitamin C requirement). Basically, lemons are not eaten as a fruit. In food preparation, lemon juice or lemon rind are mainly used; thus, lemons flavor a variety of sauces, fish and meat dishes, cakes and desserts.

Due to its high acid content, lemon juice can protect other fruits and vegetables from oxidizing; i.e., lemon juice can prevent sliced apples from turning brown.
