Lemon Tree, Detailed Facts on Lemon Trees

Here is some general information on the lemon tree.

The lemon is both a small evergreen tree (Citrus - limon, often given as C. limon) native to Asia, and the tree's oval yellow fruit. The fruit is used for culinary and nonculinary purposes throughout the world - primarily for its juice, though the pulp and rind (zest) are also used, mainly in cooking and baking. Lemon juice is about 5% to 6% (approximately 0.3 M) citric acid, which gives lemons a sour taste, and a pH of 2 to 3. This makes lemon juice an inexpensive, readily available acid for use in educational science experiments. Many lemon-flavored drinks and candies are available, including lemonade and sherbet lemons. The distinctive sour taste of lemon juice makes it a key ingredient in many dishes across the world.

The exact origin of the lemon has remained a mystery, though it is widely presumed that lemons first grew in India, northern Burma, and China. In South and South East Asia, it was known for its antiseptic properties and it was used as an antidote for various poisons. Lemons entered Europe (near southern Italy) no later than the 1st century AD, during the time of Ancient Rome. However, they were not widely cultivated. It was later introduced to Persia and then to Iraq and Egypt around AD 700. The lemon was first recorded in literature in a 10th century Arabic treatise on farming, and was also used as an ornamental plant in early Islamic gardens. It was distributed widely throughout the Arab world and the Mediterranean region between AD 1000 and AD 1150. The genetic origin of the lemon, however, was reported to be hybrid between sour orange and citron.

The average lemon contains approximately 3 tablespoons of juice. Allowing lemons to come to room temperature before squeezing (or heating briefly in a microwave) makes the juice easier to extract. Lemons left unrefrigerated for long periods of time are susceptible to mold.

Lemon juice, rind, and zest are used in a wide variety of culinary applications:

Lemon juice is used to make lemonade, soft drinks, and marinades for both fish, where its acid neutralizes amines in fish by converting them into nonvolatile ammonium salts, and meat, where the acid partially hydrolyzes tough collagen fibers, tenderizing the meat, but the low pH denatures the proteins, causing them to dry out when cooked.
Lemon juice is also used as a short-term preservative on certain foods that tend to oxidize and turn brown after being sliced, such as apples, bananas and avocados, where its acid denatures the enzymes which cause browning and degradation. Lemon juice and rind are used to make marmalade and lemon liqueur.

Lemon slices and lemon rind are used a garnish for both food and drinks.
Lemon zest, the grated outer rind of the fruit, is used to add flavor to baked goods, puddings, rice and other dishes.

Pickled lemons are a Moroccan delicacy.

Lemons were the primary commercial source of citric acid prior to the development of fermentation-based processes.

A halved lemon is used as a finger moistener for those counting large amounts of bills, such as tellers and cashiers.

The peel oil is used as a wood cleaner and polish, where the solvent property of d-limonene is employed to dissolve old wax, fingerprints, and grime.

A halved lemon dipped in salt or baking powder can be used to brighten copper cookware. The acid dissolves the tarnish and the abrasives assist the cleaning.
As a sanitary kitchen deodorizer the juice can deodorize, remove grease, bleach stains, and disinfect; when mixed with baking soda, it can remove stains from plastic food storage containers.
