Product Description

Introduction

Konjac Powder is derived from the corms of Amorphophallus konjac, a high-value functional ingredient rich in Konjac Glucomannan (KGM), a natural water-soluble dietary fiber. Sourced from premium konjac corms in China’s Yunnan, Guizhou, Sichuan and Hubei (accounting for 60% of global output), our raw materials grow in pollution-free high-altitude areas with optimal conditions.

Adopting advanced low-temperature physical extraction and purification technology (free of chemical solvents and additives), the process ensures naturalness and safety, maximizing active ingredient retention while removing impurities for high purity.

KGM content ranges from 80% to 95% (customizable), higher than the industry average (70%-85%), with a molecular weight of 200,000-2,000,000 Daltons and excellent gel-forming, thickening and water-absorbing properties.

Differentiation Advantages: Ultra-high purity (KGM up to 95%, ash ≤3.0%), stable quality (consistent viscosity 20,000-40,000 mPa·s and particle size 40-120 mesh), and versatile applicability (forms reversible/irreversible gels). It is listed as a common food in China with no usage restrictions.

Key Active Compounds

The core active component is Konjac Glucomannan (KGM), a non-ionic water-soluble heteropolysaccharide composed of D-glucose and D-mannose (molar ratio 1:1.4-1.6), with 5%-10% acetylation that affects its solubility and gel properties.

Auxiliary components include trace natural polysaccharides, amino acids, vitamins and minerals, which enhance nutritional value without affecting core functions.

Benefits

Health Benefits

  • Weight Management: KGM swells in the stomach to increase satiety, reduce food intake and support metabolic health.

  • Blood Glucose Regulation: Slows carbohydrate digestion, reduces postprandial blood glucose peak and improves insulin sensitivity.

  • Cardiovascular Health: supports healthy lipid levels, reducing vascular wellness risk.

  • Gut Health Promotion: Acts as a prebiotic to regulate intestinal flora, promote peristalsis and alleviate constipation.

  • Detoxification: Promotes excretion of metabolic wastes, reducing digestive system burden.

Functional Benefits

  • Gel-Forming Property: Forms stable reversible/irreversible gels, suitable for konjac-based foods and vegetarian alternatives.

  • Thickening & Stabilizing Property: Improves product viscosity and stability, preventing stratification.

  • Water-Retaining & Binding Property: Prevents drying/shrinkage and improves texture of meat, baked and pasta products.

  • Film-Forming Property: Forms biodegradable edible films for food packaging and preservation.

Application Cases

Food Industry

  • Functional & Health Food: Core ingredient in weight-loss, dietary fiber and blood glucose-lowering products (dosage: 5%-15%).

  • Conventional Food:

  • Gel Foods: Konjac tofu, noodles, vegetarian meat (8%-20%).

  • Baked Goods & Pasta: Bread, cakes, noodles (2%-5%).

  • Dairy & Beverages: Yogurt, juices, ice cream (0.5%-3%).

  • Meat Products: Ham, sausages (1%-4%).

Pharmaceutical Industry

Used as pharmaceutical excipient for sustained-release tablets/capsules and in drugs for constipation, hyperlipidemia and type 2 metabolic balance.

Cosmetics & Personal Care

Added to masks, lotions and hair care products as moisturizer/thickener (1%-5%), locking moisture and stabilizing formulas.

Other Industries

  • Animal Feed: Improves digestion and reduces waste (2%-5%).

  • Environmental Protection: Removes heavy metals and pollutants from wastewater.

  • 3D Printing: Used as biodegradable bio-based material.
