Wheat noodles
Also known as: wheat flour noodles
Wheat noodles are made from wheat flour, water and salt: with the alkaline water kansui they turn yellow and springy, like ramen, and without it they stay white and soft, like udon and somen.
Wheat noodles are noodles made from wheat flour, water and salt. They come in two branches: alkaline noodles, kneaded with the alkaline water kansui, and plain noodles without it. Ramen, chūka soba and tanmen belong to the first branch; udon, hiyamugi, somen and flat kishimen to the second.
Japanese rules describe this very simply. Fresh udon is wheat flour kneaded with water and cut into noodles. Chinese noodles, chūka men, are wheat flour kneaded with kansui. For dried noodles without alkali the name depends on thickness: 1.7 mm or more is udon, 1.3 to 1.7 mm hiyamugi, under 1.3 mm somen.
It is the alkali that makes ramen noodles yellow and springy, while udon, made without it, stays white and soft.
Why it matters to you. All wheat noodles contain gluten. A yellow colour does not mean the noodles contain egg: look for kansui or the carbonates E500 and E501 in the ingredients.

Frequently asked questions
What are wheat noodles?
Noodles made from wheat flour, water and salt. They are either alkaline, made with kansui like ramen, or plain like udon, hiyamugi and somen.
How do ramen noodles differ from udon?
Ramen noodles are kneaded with the alkaline water kansui, so they are yellow and springy. Udon is only wheat flour and water, white and soft.
Why are ramen noodles yellow?
Because of the alkali: natural flavones in wheat flour turn yellow at alkaline pH. So the yellow colour comes from kansui, not necessarily from egg.
How much kansui goes into the dough?
Researchers give 0.5 to 1.7 % of the flour weight; one recipe uses 1 g of kansui and 1.75 g of salt per 100 g of flour.
Is it true that yellow noodles are always egg noodles?
No. Alkaline noodles get their yellow colour from flour flavones, which turn yellow at alkaline pH once kansui is added. Egg is not always among the ingredients.
