Tempe (aliment)

Tempeh or tempe (ˈtɛmpeɪ; témpé, tempe) is a traditional Indonesian food made from fermented soybeans. It is made by a natural culturing and controlled fermentation process that binds soybeans into a cake form. A fungus, Rhizopus oligosporus or Rhizopus oryzae, is used in the fermentation process and is also known as tempeh starter. It is especially popular on the island of Java, where it is a staple source of protein. Like tofu, tempeh is made from soybeans, but it is a whole-soybean product with different nutritional characteristics and textural qualities. Tempeh's fermentation process and its retention of the whole bean give it a higher content of protein, dietary fiber, and vitamins. It has a firm texture and an earthy flavor, which becomes more pronounced as it ages. The term tempe is thought to be derived from the Old Javanese tumpi, a whitish food made of fried batter made from sago or rice flour which resembles rempeyek. The historian Denys Lombard also suggests that it could be linked to a later term tape or tapai which means 'fermentation'. In the western world, tempeh is the most common spelling. This is done to prevent readers from incorrectly pronouncing the word as "temp". The first known usage of this spelling is in an 1896 German article. Other spellings, such as témpé, were also used, but tempeh has become the standard spelling in English since the 1960s. Tempeh originated in Indonesia, almost certainly in central or east Java with an estimated discovery between a few centuries ago to a thousand years or more. The invention of tempeh cannot be separated from the origin of the fungus, which is the important part of the fermentation. This fungus consists of a mycelium that grows on teakwood and sea hibiscus leaves, which native Javanese people often used (and still do) as food wrappings. In fact, in traditional tempeh making, an usar (a mycelium-filled leaf) is used, instead of store-bought ragi. The type of soybean first used to make tempeh was the black soybean, which was a native plant.
