The largest production capacity in Taiwan, the “TSMC of bean threads”

The ingredients of Jung Nung bean threads are high-grade potato starch and pea starch imported from Europe,

and mung bean starch imported from Thailand.The Jinde Factory uses more than 120 20-foot containers of potato starch each year

to produce an annual output of 2.04 million kilograms of bean threads.

The annual consumption of potato starch at the Nangang Factory can reach about 360 containers and its annual production volume

of bean threads can reach 6.12 million kilograms. The combined production volume of both factories is 8.16 million kilograms per year.


Jung Nung product quality   Generations of artisanal expertise

Jung Nung products are all made from natural starch through an artisanal process handed down for generations.

We never add any additives such as maltodextrin (soluble corn fiber), artificial thickeners or other artificial additives.

In our rigorous production process, we never mix in other starches (cassava flour, etc.) or artificial additives,

which is why our bean threads have great elasticity, translucent appearance, smooth texture and strong cohesion after cooking

 and a refreshing and pleasant viscosity that no other brand can offer. (tender with a bite, translucent and smooth)

Our bean threads are divided into four types according to their width: broad, standard, narrow and fine.

The greater the width, the more difficult it is to make. Combining width with thinness requires high standards and manufacturing expertise.

Jung Nung bean threads are different from other broad bean threads in the market.

They have a unique “Q factor” (or bite) yet they have a smooth and tender texture as well as translucent appearance. Broad, thin, tender, chewy, smooth,

and with a high absorption capacity for soup and sauce—traditional bean threads crafted to perfection.

(Wide, thin, tender, chewy) (Unique production technology) (standard width and ultra-thin)

[Baoding] Top-End Pure Mung Bean Bean threads from mung bean starch contain natural dietary fiber and natural chlorophyll

 without any artificial maltodextrin added to replace natural dietary fiberas is the case in many other bean threads in the market.
