Description
Technical Parameters

This product is a high-purity, food-grade konjac glucomannan powder (CAS No. 37220-17-8) derived from premium *Amorphophallus konjac* grown in China's high-altitude regions. It is produced through a rigorous process involving selection, peeling, low-temperature drying, fine grinding, multi-stage purification, decolorization, impurity removal, and aseptic refining. Processed entirely via physical methods, it is free from chemical modification, bleaching agents, additives, and solvent residues, making it a natural, water-soluble dietary fiber ingredient highly acclaimed in the international market.
Konjac glucomannan is a high-molecular-weight plant polysaccharide characterized by an exceptionally high expansion ratio, strong water absorption, excellent thickening and gelling properties, and superior suspension stability. It is also fat-free, low-calorie, and highly satiating. The product appears as a fine, white-to-off-white powder with high purity; it is odorless, free from black specks or impurities, flows well, and resists clumping. Upon contact with water, it swells rapidly-expanding to 80–120 times its own weight-to form a highly viscous, transparent gel with a smooth, refined mouthfeel and no gritty residue. It is an essential, high-demand ingredient for sectors such as meal replacements, blood-sugar-control foods, healthy dietary products, nutritional supplements, and vegetarian gel applications.

 

Seven Core Product Advantages

1. Ultra-high purity, high viscosity, and high activity

Derived from carefully selected, mature, high-quality konjac corms, our product undergoes peeling and purification processes that drastically reduce starch and ash content. It boasts a high concentration of active glucomannan and delivers robust, stable sol viscosity. At the same dosage, it far outperforms standard, low-cost konjac powders in terms of satiety, thickening power, and gel strength. Batch-to-batch viscosity remains consistent-eliminating fluctuations-making it ideal for standardized production by overseas brands.

2. Superior water absorption and swelling; ultimate satiety; a core ingredient for hit meal-replacement products

KGM (Konjac Glucomannan) offers industry-leading water absorption and swelling capabilities. It rapidly swells in cold water to form a full-bodied gel; once in the stomach, it provides lasting fullness, slows digestion, and curbs hunger for extended periods. It is a highly sought-after natural dietary fiber ingredient for overseas "Slim," "Diet," "Keto," and weight-management product lines, enjoying strong recognition among consumers in Europe and North America.

3. Zero fat, low sugar, low calorie; a natural, blood-sugar-friendly ingredient

This product is free from fat and sucrose, low in calories, and has a low glycemic index (GI). It resists rapid digestion and absorption by the body, preventing blood sugar spikes and fat accumulation. It aligns perfectly with global trends favoring sugar-free, low-fat, light-meal, blood-sugar-conscious, and diabetic-friendly foods, making it a preferred "clean-label" ingredient for health-conscious food brands.

4. Excellent gelling and stability; exceptional formulation compatibility

Konjac glucomannan possesses unique gelling properties effective in both hot and cold applications. It blends seamlessly with xanthan gum, guar gum, carrageenan, and locust bean gum to provide synergistic thickening, enhance gel elasticity, and improve texture.

In beverages, meal-replacement shakes, puddings, vegan jellies, and meat products, it serves multiple functions: suspension, anti-separation, water retention, thickening, structural stabilization, and mouthfeel enhancement. It ensures outstanding system stability and withstands high temperatures and refrigeration, resulting in a long shelf life.

5. Fine, translucent powder yielding a clear, impurity-free gel

Through multiple stages of fine grinding and precision filtration, the powder achieves uniform fineness and high purity, with minimal black specks and no coarse residue. Upon dissolution, the resulting gel is transparent and clear-free from turbidity or grittiness-making it ideal for premium transparent beverages, gel-based desserts, and high-end powdered health supplements, resulting in products with superior visual appeal and texture.

6. Purely physical processing: Clean Label and worry-free export compliance

Processed entirely via low-temperature physical methods without chemical bleaching, sulfur treatment, chemical modification, or preservatives. The ingredient list features a single component-Konjac Glucomannan-aligning perfectly with "Clean Label" standards and consumer trends in Europe and the US favoring natural, organic, and healthy products; this facilitates smoother retail audits and customs clearance.

7. Stable export supply chain capable of reliable, long-term bulk delivery

Backed by proprietary raw material cultivation bases and modern dust-free production lines, we maintain year-round stock reserves of over 10,000 tons to ensure uninterrupted supply. We offer neutral/unbranded export packaging, OEM/private labeling, and customization of fineness and viscosity specifications. Services range from sample provision and consolidated shipments to full-container bulk exports, supported by a complete suite of documentation, including COA, SDS, microbiological reports, HALAL, and KOSHER certifications.
