Introduction

Konjac Extract is obtained from the tubers of Amorphophallus konjac, a perennial plant native to Asia and widely cultivated in China and Japan. For centuries, konjac has been valued in traditional Asian diets as both a health food and a culinary ingredient, used to make konjac noodles, jellies, and functional foods.

The extract is standardized to glucomannan, a natural water-soluble dietary fiber known for its strong swelling and gelling properties. Glucomannan absorbs water and expands in the stomach, which promotes satiety, helps reduce calorie intake, and supports weight management. It also contributes to maintaining healthy blood sugar and cholesterol levels by slowing carbohydrate absorption and binding bile acids.

Commercial production involves careful cleaning, drying, and milling of konjac tubers, followed by extraction and purification to achieve high glucomannan concentration. The resulting extract is a fine white to off-white powder, highly water-soluble, and stable under proper storage. It is widely used in nutraceuticals, weight management products, functional foods, and dietary fiber supplements.

Product Processing 

f84fce27-f2d4-490b-adf8-8ff1cbd3b43f

Standard and Certificates 

All of our products are made in a GMP-compliant facility where every step of production is carefully managed. Over the years, our factory has passed several well-recognized audits, including HACCP, ISO22000 and ISO9001. The products also meet Kosher and Halal requirements, and we hold FDA registration as well. These certifications reflect the standards we follow rather than just labels we collect—they’re part of how we ensure consistency and safety in every batch. 


Free Sample Available 

If you’d like to get a feel for the product before placing an order, we can send you a free sample. In most cases, we provide around 10–20 grams so you can evaluate the quality yourself. For items with higher raw material costs, we will confirm the exact amount we can offer so everything is clear before shipping. 


Standard Packaging and Private Label 

For regular shipments, we usually pack goods in 1–5 kg aluminum foil bags, 10–20 kg cartons, or 10–30 kg fiber drums, depending on the item and order size. 
If you’re planning to sell under your own brand, we also handle private labeling. We can help design and produce packaging with your logo or artwork so the products arrive ready for retail. Many customers find this saves them a lot of time compared with printing and repacking on their end. 

Shipping Method 

Orders under one metric ton are generally shipped through major express couriers such as DHL, FedEx, UPS or EMS. For larger quantities, we can arrange transport by sea or railway. The best method depends on your location and how quickly you need the goods, so we’ll help you choose the most practical option. 


After Sale Services 

Most of our products remain stable for up to two years, and we guarantee their quality within that period. If anything arrives below your expectations, our return process is straightforward. You can send back the portion in question, and we will refund the corresponding amount—no complicated procedures or hidden conditions.
