What Is Kansui in Ramen Noodles?

Kansui is an alkaline ingredient traditionally used in many ramen noodles. It contributes to their characteristic firm, springy texture and often their yellowish color, even when no egg is present.

What alkalinity changes

• The alkaline environment changes how wheat proteins and starch behave during noodle making.
• Some packaged noodles use alkaline salts such as sodium carbonate or potassium carbonate.
• Egg noodles and alkaline ramen noodles are not automatically the same product.
• Follow the noodles’ package cooking time because fresh and dried textures vary.

What to avoid

Do not make high-alkalinity noodle additives by guessing chemical quantities; follow a tested recipe or buy prepared noodles.

Frequently asked question

Does kansui make ramen gluten-free?

No. Typical ramen noodles are made from wheat flour and contain gluten unless specifically labeled otherwise.
