Instant noodles are a precooked and usually dried noodle block, sold with flavoring powder and/or seasoning oil. The flavoring is usually in a separate packet, although in the case of cup noodles the flavoring is often loose in the cup. Some instant noodle products are seal packed; these can be reheated or eaten straight from the packet. Dried noodle blocks are cooked or soaked in boiling water before eating.
The main ingredients used in dried noodles are wheat flour, palm oil, and salt. Common ingredients in the flavoring powder are salt, monosodium glutamate, seasoning, and sugar. The dried noodle block was originally created by flash frying cooked noodles, and this is still the main method used in Asian countries, though air-dried noodle blocks are favoured in Western countries.
Instant noodles were invented by Momofuku Ando (born Go Pek-Hok) of Nissin Foods in Japan. They were launched in 1958 under the brand name Chikin Ramen. In 1971, Nissin introduced Cup Noodles, a dried noodle block in a polystyrene cup. Instant noodles are marketed worldwide under many brand names.
Ramen, a Japanese noodle soup, is sometimes used as a descriptor for instant noodle flavors by some Japanese instant noodle manufacturers (as Indomie use Mie goreng as a descriptor for their Mi goreng range). It has become synonymous in America for all instant noodle products.
