Kelp Noodles

Origin

While coastal Asia has eaten seaweed for millennia, kelp noodles are a relatively modern product developed as a low-calorie, mineral-dense noodle alternative. They gained traction in the 2000s with raw, paleo, and keto diets thanks to minimal processing, low carbs, and the natural mineral profile of brown seaweed.

How to make them

Kelp noodles combine kelp, sodium alginate from brown seaweed, and water. They are purchased ready-made and softened at home.

1. 01

   Raw kelp is harvested, cleaned, and processed.

2. 02

   Sodium alginate helps form a stable noodle structure.

3. 03

   The mixture is shaped into thin, translucent strands.

4. 04

   Noodles are rinsed and packed for sale.

5. 05

   Before eating: rinse, then soak 10–30 minutes in water with lemon juice or vinegar to soften.

Storage

Unopened packages keep at room temperature or refrigerated up to about a year. After opening, store submerged in water airtight and use within 3–5 days. Flavor intensifies over time, so fresher is better.
