Konjac, a traditional plant native to southern and southwestern China, is increasingly gaining global recognition for its nutritional benefits and versatile applications in food production. At the heart of its popularity is konjac gum, a dietary fiber extracted from the plant’s tuber. This natural polysaccharide is low in calories and protein, but rich in glucomannan, making it ideal for health-conscious consumers and weight management.

What Is Konjac Gum?

Konjac gum is composed of D-mannose and D-glucose in a specific ratio:

Chemical Composition

D-mannose : D-glucose = 1 : 1.6

At our Anzhou facility in Sichuan, Eastern Morning produces premium-grade konjac gum with viscosity levels up to 40,000 mPa·s, ensuring superior performance in industrial food production.

When dissolved in water, it forms a high-viscosity solution. After undergoing alkali treatment, it turns into an elastic, thermally irreversible gel. These unique characteristics allow konjac gum to be used in a variety of food products, such as konjac cake, tofu, vermicelli, and even bionic foods that mimic textures of seafood or meat.

Synergistic Effects with Other Hydrocolloids

One of the most valued properties for R&D professionals is konjac gum’s synergy with other hydrocolloids.
When mixed with xanthan gum or carrageenan, it creates a much stronger and more elastic gel than any of these ingredients used individually.

This synergy allows manufacturers to reduce total gum dosage, lowering costs while achieving a superior clean-label stabilizer system for complex foods.

Konjac-Based Gel Foods

Thanks to its gel-forming, emulsifying, thickening, and stabilizing properties, konjac is widely used in gel-based food production. These properties remain stable even in acidic or salty environments. The result is food that offers a smooth texture, improved gelatinity, and better mouthfeel.

Popular konjac-based gel foods include:

• Konjac tofu
• Konjac vermicelli
• Konjac cake
• Konjac soft candy
• Konjac yogurt and ice cream
• Konjac-based bubble tea pearls

Konjac Tofu

Konjac tofu is a traditional food with a distinctive taste and texture. It is typically made using either konjac powder or fresh konjac. Known for being simple to produce and highly versatile, konjac tofu is especially appealing to health-conscious and vegetarian consumers.

Konjac Vermicelli

Traditional vermicelli, often made from mung beans, rice, or potatoes, can suffer from issues like brittleness or murky soup. By incorporating konjac glucomannan into the mixture, these noodles gain:

• Better elasticity
• Enhanced toughness
• Improved cooking quality
• No chemical additives needed (like alum)

Konjac Cake

Konjac cake is made by blending konjac flour into traditional cake recipes. The inclusion of konjac helps enhance the cake’s structure, moisture retention, and gelling properties, creating a healthier dessert option that doesn’t compromise on texture or appearance.

Bionic Konjac Foods

Innovation Spotlight

One of the most innovative uses of konjac is in bionic foods, which simulate the texture and taste of meat and fruit pulp.

Bionic Meat Products (Plant-based Meat Alternatives)

Due to konjac’s high water retention and ability to form porous, thermally irreversible gels, it is a critical ingredient for the plant-based meat industry.

Manufacturers use our high-purity glucomannan to replicate the elastic mouthfeel and juiciness of real animal protein.
It serves as a clean-label binder for:

• Vegan sausages
• Meatless patties
• Vegetarian seafood analogues

Bionic Fruit Pulp (Texture Enhancers for Beverages)

By blending konjac powder with natural fruit juices and flavorings, manufacturers can create “bionic fruit pulp” or texture-enhancing toppings. These are widely used as:

• Bubble Tea Pearls & Toppings
  Providing a chewy, resilient texture that stays stable in both hot and cold acidic drinks.

• Fruit Juice Suspensions
  Acting as a stabilizer to give beverages a “pulpy” mouthfeel without the high cost of fresh fruit processing.

• Confectionery Fillings
  Enhancing the “pop” sensation and fullness of liquid-filled snacks.

Other Food Applications of Konjac

Beyond the common products, konjac is also integrated into various other food items:

Traditional Applications:
• Konjac fruit peels
• Konjac rice cakes
• Ice cream

Modern Noodle Products:
• Ramen and instant noodles
• Knife-cut noodles
• Sliced noodles

Dumpling Applications:
• Wonton skins
• Shaomai wrappers
• Other dumpling wrappers

In these applications, konjac improves product form, texture, and resilience, making it a versatile ingredient for both modern food manufacturing and traditional recipes.

Final Thoughts

Konjac gum represents a perfect blend of traditional food wisdom and modern food technology innovation. Its unique properties make it an invaluable ingredient for creating healthier, more functional food products that meet the growing consumer demand for nutritious, low-calorie alternatives.

As the food industry continues to evolve toward healthier and more sustainable options, konjac-based ingredients will undoubtedly play an increasingly important role in shaping the future of food production and consumption.
