− | The '''lemon''' (''Citrus × limon'') is a [[hybrid]] [[citrus]] [[tree]] of cultivated origin. The [[fruit]] are used primarily for their [[juice]], though the [[pulp]] and [[peel (fruit)|rind]] ([[zest (ingredient)|zest]]) are also used, primarily in [[cooking]] or mixing. Lemon juice is about 5% [[citric acid]], which gives lemons a [[Basic taste#Sourness|sour]] taste and a [[pH]] of 2 to 3. This [[acid]]ity makes lemon juice a cheap, readily available acid for use in educational [[chemistry]] experiments. | + | The '''lemon''' (''Citrus × limon'') is a [[hybrid]] [[citrus]] [[tree]] of cultivated origin. Trees can reach 10 meters (33 feet), but usually are smaller. Branches are thorny, forming an open crown. Leaves are green, shiny and [[leaf shape|elliptical-acuminate]]. [[Flower]]s are white on the outside with a violet streaked interior and have a strong [[fragrance]]. Flowers and ripe fruits can be found on the tree at the same time. |

− | The lemon is a cultivated hybrid deriving from wild species such as the [[citron]] and [[Mandarin orange|mandarin]]. When and where this first occurred is not known. The citron – apparently the fruit described in [[Pliny's Natural History]] (XII, vii.15) as the ''malum medicum'', the "medicinal fruit" – seems to have been the first citrus fruit known in the Mediterranean world. Depictions of citrus trees appear in [[Roman Empire|Roman]] [[mosaic]]s of [[North Africa]], but the first unequivocal description of the lemon is found in the early 10th-century [[Arabic language|Arabic]] treatise on farming by [[Qustus al-Rumi]]. The use and cultivation of the lemon, by the Cantonese (Southern Barbarians) is noted in the early 12th century. At the end of the 12th century, Ibn Jami', personal physician to the Muslim leader [[Saladin]], wrote a treatise on the lemon, after which it is mentioned with greater frequency in the Mediterranean. However, it is believed that the first lemons were originally cultivated in the hot, semi-arid [[Deccan Plateau]] in [[Geography of India|Central India]].

− | The origin of the name ''"lemon"'' is through [[Persian language|Persian]] (لیمو ''Limu'' [pronounced with long e and short u]), akin to the [[Sanskrit]] ''nimbuka''. They were cultivated in [[Genoa]] in the mid-15th century, and appeared in the [[Azores]] in 1494. More recent research has identified lemons in the ruins of [[Pompeii]].<ref>Russell, Tony & Catherine Cutler (Hermes House 2004) Trees, an Illustrated Identifier and Encyclopedia Aness Publishing. </ref> Lemons were once used by the British [[Royal Navy]] to combat [[scurvy]], as they provided a large amount of [[Vitamin C]].

− | Both lemons and [[lime (fruit)|limes]] are regularly served as [[lemonade]] or [[limeade]], its equivalent, or as a [[garnish (food)|garnish]] for drinks such as [[iced tea]] or a [[soft drink]], with a slice either inside or on the rim of the glass. Only lemons, however, are used in the Italian liqueur [[Limoncello]]. A wedge of lemon is also often used to add flavor to water. The average lemon contains approximately 3 tablespoons of juice. Lemons warmed to room temperature before squeezing (in a [[Microwave oven|microwave]] or by leaving on a counter) increases the amount of juice that can be extracted. Storing lemons at room temperature for long periods makes them more vulnerable to [[mold]].

− | Lemons also make a good short-term preservative, commonly used on sliced apples. This keeps the fruit crisp and white for about a day, preventing the unappetizing browning effect of oxidization. This helps to prolong the usage of the fruit.

− | Lemons and other citrus fruits contain amounts of different [[chemical]]s and are thought to have some health benefits. They contain a [[terpene]] called [[limonene]] which gives their characteristic lemon smell and taste. Lemons contain significant amounts of [[citric acid]]; this is why they have a low pH and a sour taste. They also contain [[Vitamin C]] (Ascorbic acid) which is essential to human health. 100 [[litre|milliliter]]s of lemon juice contains approximately 50 [[gram|milligram]]s of Vitamin C (55% of the recommended daily value) and 5 [[gram]]s of citric acid.

The electricity generated may also be used to power a motor to move the lemons (on wheels) like a car or truck. These experiments also work with other fruit like apples and with [[potato]]es.

− | Several other plants have a similar taste to lemons. In recent times, the Australian bush food [[Lemon myrtle]] has become a popular alternative to lemons.<ref>*[http://www.teachers.ash.org.au/bushtucker/lemon_myrtle.html Lemon Myrtle]</ref> The crushed and dried leaves and edible essential oils have a strong, sweet lemon taste, but contain no citric acid. Lemon myrtle is popular in foods that curdle with lemon juice, such as [[cheesecake]] and [[ice cream]].
