Product Introduction

Our product is the highest grade of natural hydrocolloid, taken from the first-grade Amorphophallus konjac tubers that are grown in our certified planting bases. This is an off-white powder that contains a minimum of 90% Glucomannan, as confirmed by UV spectrophotometry, ensuring the reliable performance of your compositions. The substance is very soluble and generates very viscous solutions at even at very low doses. Each batch is fully tested for active ingredients, pesticide residues, heavy metals and microbiological contamination before it leaves our facility. Our extract can be relied on by manufacturers as a clean-label ingredient solution, available in compact 25kg drums and Packaging options to suit your needs, with full documentation and timely delivery from our diverse warehouse system.

Third-Party Test Report

Testing Authority: We work with internationally recognised third-party laboratories such as SGS, Eurofins, etc. to ensure a full range of testing services to verify product quality and safety.

Pesticide Residue Analysis: Multi-residue screening confirms compliance with EU and US regulatory limits, ensuring agricultural chemical levels remain well below maximum residue limits for over 500 compounds.

Heavy Metals Testing: Testing with ICP-MS confirms lead, arsenic, cadmium and mercury levels are within strict food-grade standards, often with findings well below codex limits.

Konjac Extract Powder Advantages

Superior Water Binding Capacity: Our extract can bind up to 100 times its own weight of water, producing phenomenal viscosity at levels as low as 0.3-0.5%. This means great savings in your formulation expenses, and incredible textural qualities.

Clean Label Appeal: This single-ingredient, non-GMO, plant-based fibre source with natural origin certification helps you address customer demand for recognisable ingredients without artificial additives or chemical changes.

Thermal Stability: The structure of glucomannan is thermally stable, allowing its use over a wide temperature range. It works well in hot-fill systems and freeze/thaw cycles without a substantial loss of viscosity or syneresis.

Konjac Powder In Food

Konjac Extract Powder Application

Food Manufacturing: Is a premium thickening and gelling agent in noodles, jellies, jams, dairy products and bakery goods, offering better texture, moisture retention and shelf-life extension.

Beverage Formulation: It is used as a suspension ingredient and viscosity modifier in functional drinks, smoothies, and plant-based beverages to avoid sedimentation and achieve a pleasing mouthfeel.

Dietary Supplements: Used in weight control formulations and digestive health products, taking advantage of its excellent fibre content to enhance satiety and maintain gastrointestinal health.

Production Process

Step 1 – Selection of Raw Materials: Carefully choose mature Konjac Extract Powders from our certified planting bases, which have a growth duration of at least 12 months. We only use the best quality raw materials with the correct glucomannan content for manufacture.

Step 2 – Cleaning and Slicing: Clean the tubers properly to remove soil and other contaminants. Slice them to a regular thickness so that they are processed evenly. Clean, standardised raw material, ready for effective extraction.

Step 3 – Drying: The drying process is managed at low temperature to reduce moisture content while maintaining the glucomannan molecular structure. Result: Stable intermediate product with increased shelf life and retained functional qualities.

Step 4 – Milling: Use accurate milling equipment to grind dried slices to the required particle size distribution. Result: Fine powder with optimal surface area for extraction efficiencies in later stages.

Step 5 – Alcohol Precipitation: Add milled powder to a food-grade ethanol solution to selectively precipitate the high purity glucomannan, eliminating starches, proteins and colours. Result: glucomannan fraction with dramatically increased purity.

Step 6 – Washing and Dehydration: The precipitated glucomannan is washed several times with ethanol to remove any remaining impurities and the solvent is removed by centrifugation. Ultra-high purity glucomannan with a low level of impurities.
