What is Konjac?

Konjac is an Asian plant that belongs to the family Araceae. It grows in China, Japan and Southeast Asia and has been used as traditional food for over 2, 000 years. The edible part of this plant comes from its corm .

Konjac contains glucomannan – a soluble dietary fiber that can absorb up to 50 times its weight in water. This makes it useful in traditional medicine and food products.


Why are konjac noodles considered healthy?

Answer: Konjac noodles are low-calorie , low-carb and gluten-free. They are also rich in soluble fiber which can aid digestion and help manage blood sugar levels.

How are konjac noodles made?

Answer: The first step involves harvesting the corms of the konjac plant after two to three years of growth using hand tools or machines depending on the scale of production.

Once harvested, the corms undergo processing that includes cleaning and slicing them into small pieces which undergo several rounds of washing with clean water until all impurities have completely washed away.
Next, the processed slices get dried out before undergoing milling/grinding by special mills that turn them into powder form known as ‘konnyaku flour’.

The final stage involves mixing this powder with natural calcium hydroxide solution through different forms by passing them through extrusion machines.

Once it has been formed into noodles, they are cooked in boiling water for up to 10 minutes or until they become somewhat transparent and soft. They can now be combined with sauce or used as a base for stir-fry dishes.

What other products can be made from konjac flour?

Answer: Konjac flour is also used as a thickening agent , vegetarian gelatin substitute known as “konnyaku jelly” and vegan seafood alternatives like scallops, squid, fish fillet imitation just to mention but a few.

And that’s the process of how konjac noodles come about- Whether you’re looking for healthy options or simply love the unique texture of these guilt-free noodles, give them a try!

Ingredients in Konjac Noodle Manufacturing

Konjac noodles are a popular low-carb and low-calorie alternative to traditional wheat-based noodles. Made from the root of the konjac yam, these translucent and gelatinous noodles have become a staple in many healthy diets. But what exactly goes into making these unique noodles? Let’s take a closer look at some of the ingredients involved in konjac noodle manufacturing.

What is Konjac Yam?

Before diving into the specific ingredients used in konjac noodle production, it’s important to understand what konjac yam is. Also known as elephant yam or devil’s tongue, this starchy root vegetable is native to Southeast Asia and has long been used as an ingredient in traditional Asian cuisine and medicine.

The edible part of the konjac yam is its corms, which resemble sweet potatoes but have a much higher concentration of glucomannan – a water-soluble dietary fiber that gives konjac noodles their unique texture.

Glucomannan Powder

As mentioned above, glucomannan powder is derived from the konjac yam’s corms and forms the foundation of all konjac noodles. This odorless and tasteless white powder can absorb up to 50 times its weight in water, creating a thick gel-like substance when mixed with liquid.

In addition to its role as a thickening agent, glucomannan also has numerous health benefits. Studies have shown that consuming glucomannan can help lower cholesterol levels, regulate blood sugar levels, promote fullness and aid in weight loss efforts.

Calcium Hydroxide

Calcium hydroxide is another key ingredient used in manufacturing konjac noodles. This food-grade compound helps break down raw konjac corms by softening their structure and removing any bitter tastes or odors.

Once dissolved into water at specific concentrations, calcium hydroxide creates an alkaline solution that is used to soak the sliced konjac corms before further processing.


Water is a crucial ingredient in creating konjac noodles. From soaking and boiling the sliced corms to rinsing and adding glucomannan powder, clean water is needed at various stages throughout the manufacturing process.

Using purified or distilled water can ensure that other impurities and minerals do not alter the taste or texture of the final product.

Citric Acid

Citric acid is often added to konjac noodles as a natural preservative. This weak acidic compound helps prevent microbial growth and spoilage by reducing pH levels in food products.

In addition to its antimicrobial properties, citric acid provides a tart flavor profile that complements many dishes featuring konjac noodles.
