Faster, Chewier Noodles with Three-Stage Extrusion

2026-01-29







Three-stage extrusion is a noodle-making technology

in which kneading and extrusion

are performed in three consecutive stages.



Unlike standard single-pass extrusion,

this process builds a tighter internal structure

step by step—

raising noodle density

while enhancing both elasticity

and a smooth, tender bite.



This structural difference

is what delivers

“firm chew” when you bite

and “clean softness” as you swallow.



The benefits are especially clear

in buckwheat noodles.



Traditional buckwheat noodles

can break easily

or loosen during boiling

due to the nature of starch.



With three-stage extrusion,

the internal structure becomes denser,

helping the strands stay continuous

without frequent breakage.



As a result,

the noodles can be boiled right away

without needing to separate strands

like typical naengmyeon noodles.



They finish with a chewy texture

in a shorter cooking time

without sticking together.



This improves cooking convenience,

reduces the chance of failure at home,

and makes timing control easier

in large-scale cooking environments.



The impact is also significant

across product applications.






The Naengcheongol series

is a lineup where the advantages

of three-stage extrusion

are immediately noticeable.



Even after rinsing in cold water,

the noodle core holds its structure well,

and the noodles cling effectively

to broth and seasonings—

delivering both satisfying chew

and a refreshing, smooth slurp.



The same staged extrusion

is also applied to newer products

such as udon noodles,

reinforcing noodle structure

so they remain springy and chewy

without turning mushy

even when left in hot soup.



This allows the technology

to support a wider range of menus—

from hot soups

to cold salads

and spicy mixed dishes—

with stable, consistent quality.



Market response has been positive.



Consumers highlight

that the noodles

“don’t break down easily

and stay chewy longer,”

and that

“texture holds up

even with short boiling time.”



Three-stage extrusion products

such as the Naengcheongol series

and udon noodles

have been welcomed

for these practical advantages.



The significance is not

in showcasing a process

for its own sake,

but in delivering real benefits—

shorter cooking times,

fewer cooking failures,

and a better everyday eating experience.
















Chilkab Nongsan

is taking the technology further

by applying three-stage extrusion

selectively

where it best fits.



Based on each ingredient’s

starch structure

and water absorption—

buckwheat, wheat, and rice—

as well as the target texture

such as springiness, softness, and elasticity,

the company continues R&D

to refine recipes.



Pressure, temperature, moisture,

and aging time

are adjusted precisely.



Rather than applying

one uniform process

to every product,

Chilkab Nongsan fine-tunes

the intensity of three-stage extrusion

to match product concepts

and cooking contexts—

broth-based, mixed, or stir-fried;

and home, foodservice,

or institutional dining.



In short,

three-stage extrusion

enhances density, elasticity,

and softness

through staged extrusion and aging.



Thanks to this technology,

buckwheat noodles

can be boiled directly

without separating strands,

achieving a chewy texture

in a short time.



Products such as

the Naengcheongol series

and udon noodles

have gained strong traction

by combining cooking convenience

with stable texture.



Chilkab Nongsan

will continue expanding

the application of three-stage extrusion

through precision process design—

bringing “better-tasting noodles”

that consumers can truly feel

in everyday meals.
