Raisins are dried grapes. They are produced in many regions of the world, such as the United States, Australia, Chile, Argentina, Mexico, Greece, Turkey, Iran, Togo, Jamaica, and South Africa. Raisins may be eaten raw or used in cooking and baking.

[edit] Etymology

The word raisin dates back to Middle English and is a loanword from Old French; in Old French and French, raisin means "grape", while a raisin in French is called a raisin sec, a "dry grape". The Old French word in turn developed from Latin racemus, "a bunch of grapes". The origin of the Latin word is unclear.

[edit] Varieties

Raisin varieties depend on the type of grape used. Seedless varieties include Thompsons, Flames, and Sultana. Raisins are typically sun-dried, but may also be "water-dipped", or dehydrated. "Golden raisins" are treated with Sulfur Dioxide (SO2) to give them their characteristic color. A particular variety of seedless grape, the Black Corinth, is also sun dried to produce Zante currants, mini raisins that are much darker in colour and have a tart, tangy flavour.

[edit] Nutritional value

Raisins are about 90% sugars by weight, of which about half is fructose and half is glucose. Raisins are also high in antioxidants, and are comparable to prunes and apricots in this regard.

[edit] Sweetness

Raisins are sweet due to their high concentration of sugars. If they are stored for a long period, the sugar inside the fruit crystallises. This makes the fruit gritty, but does not affect its usability. To de-crystalise raisins, they can be soaked in liquid (alcohol, fruit juice, or boiling water) for a short period, dissolving the sugar.

The Victorian parlour game called Snap-dragon involved raisins being plucked from a bowl of burning brandy.
