The Core Ingredient: Starch
At its most basic, the answer to "what are cellophane noodles made out of" is simply starch and water. Unlike pasta made from wheat flour or rice noodles made from rice flour, cellophane noodles get their unique translucent quality from the type of starch used. This makes them naturally gluten-free and a versatile ingredient in various Asian cuisines. The flavor of the noodle itself is quite neutral, which allows it to absorb the flavors of the sauces and broths it is cooked in.
Variety of Starches Used
The specific starch used to make cellophane noodles varies by region, influencing the noodle's texture and characteristics. The most traditional and widely used starch, particularly in China, comes from mung beans. These are often called fensi or bean thread noodles and are known for their classic, slightly gelatinous texture that becomes clear and slippery when cooked.
In Korea, sweet potato starch is commonly used to make dangmyeon, a thicker variety of cellophane noodle that turns translucent when cooked and is a key ingredient in dishes like japchae. Other starches like potato, canna, and tapioca are also used in different regions, such as in Japanese harusame noodles which are often made with potato starch. The choice of starch directly affects the final texture of the noodle, ranging from elastic to soft.
How are Cellophane Noodles Produced?
The production of cellophane noodles involves extracting and refining starch from its source. The process typically includes several steps:
- Starch Preparation: Grinding the source ingredient (like mung beans or sweet potatoes) and mixing it with water to isolate the starch.
- Slurry Creation: Combining the purified starch with warm water to form a thick, sticky mixture.
- Extrusion: Pushing the slurry through a tool with small holes to form thin strands.
- Drying: Hanging the delicate strands to dry, often in the sun, which results in the brittle, opaque white noodles found in stores.
Industrial production may involve additional steps like steaming, blanching, chilling, and further drying to ensure consistent quality. Traditionally, the process can involve extruding starch paste into boiling water and a freezing-thawing cycle to achieve the desired springy texture before drying.

Comparison Table: Cellophane vs. Rice Noodles
While both are staples in Asian cooking, cellophane and rice noodles are distinct. Here's a quick comparison:
| Feature | Cellophane Noodles | Rice Noodles |
|---|---|---|
| Primary Ingredient | Starch (Mung bean, Sweet Potato, etc.) | Rice Flour and Water |
| Appearance (Cooked) | Translucent, clear | Opaque, solid white |
| Texture | Chewy, elastic, or soft | Soft and delicate |
| Flavor Absorption | High | Moderate |
| Gluten Content | Naturally gluten-free | Naturally gluten-free |
Culinary Versatility
Cellophane noodles' neutral flavor and ability to absorb liquids make them highly versatile. Once rehydrated by soaking in hot water, they can be added to numerous dishes:
- Soups and Hot Pots: They add texture and absorb the broth.
- Stir-fries: Used in dishes like "ants climbing a tree".
- Salads: Chilled, they form the base of cold noodle salads like Thai yam wun sen.
- Fillings: Their soft texture works well in spring rolls and dumplings.
- Deep-frying: They can be deep-fried for a crispy garnish.
Conclusion
In conclusion, cellophane noodles are translucent, gluten-free noodles primarily made from starch and water. The specific starch, most commonly mung bean or sweet potato, determines their regional variation and texture. Though bland on their own, they excel at absorbing flavors, making them a versatile ingredient in diverse Asian cuisines. Understanding what are cellophane noodles made out of provides insight into their unique properties and culinary applications.
