Why Is Alkali Added To Some Noodles?

Have you ever wondered why some Asian noodles like ramen or Jook-sing noodles have that distinctive springy texture and golden hue? The secret lies in an ancient culinary trick — alkaline water. This seemingly simple ingredient unlocks a world of texture science, cultural tradition, and practical food chemistry that has sustained noodle artisans for centuries. Let's unravel why alkaline noodles became a staple across Eastern kitchens and how this kitchen alchemy works its magic.

1. Anti-Souring Property (Critical in Humid Regions)

  • Problem in South China/Southeast Asia:
         Warm, humid climates cause dough to ferment quickly, leading to unwanted sourness (lactic acid buildup).

  • Alkali Solution:
         Adding alkaline water (kansui) neutralizes acids, preventing sourness and extending freshness.
         Example: Traditional Cantonese "Jook-sing noodles" (bamboo-pressed noodles) relies on alkali for stability.

2. Enhanced Cooking Performance

  • Heat Resistance:
         Alkali strengthens gluten, making noodles more heat-resistant (ideal for parboiling or instant ramen).

  • Texture:
         Creates a denser, springier bite (e.g., Japanese ramen's "koshi" chewiness).

3. Humidity Adaptation

  • Dough Stability:
         Alkali reduces stickiness, easing handling in high-humidity environments.

  • Storage:
         Inhibits microbial growth, prolonging shelf life without refrigeration (historically vital in pre-industrial Asia).


While alkaline additives have long been essential for achieving the desired texture in some products of Liji Food’s noodles, shuch as "Handmade Jook Sing noodles", the company recognizes that traditional formulations’ odor may be challenged for some consumers. By carefully reducing alkali content and improving manufacturing process, this concern has been eliminated. 

This evolution reflects how heritage food manufacturers like Liji can adapt to global tastes without erasing tradition, proving that even centuries-old techniques have room for thoughtful refinement.
