INSTANT noodles are sold in a precooked and dried noodle block, with flavouring powder and/or seasoning oil. The flavouring is usually in a separate packet, although in the case of cup noodles the flavouring is often loose in the cup. Some instant noodle products are seal packed; these can be reheated or eaten straight from the packet/container. Dried noodle blocks are cooked or soaked in boiling water before eating.
The main ingredients used in dried noodles are usually wheat flour, palm oil, and salt. Common ingredients in the flavouring 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, but air-dried noodle blocks are favoured in Western countries.
