A Shanghai trading company that sources konjac for other people's brands, and writes down what it learns.
What konjac is A perennial root crop, Amorphophallus konjac. The underground corm is milled into konjac flour and refined into konjac glucomannan, a water-soluble fibre that swells many times its own weight when hydrated.
What we trade Glucomannan powder, konjac flour and gum (E425), shirataki noodles and konjac rice, konjac jelly and konjac sponges, in food, supplement and bulk grades, for brands, importers and manufacturers.
How we work We source from vetted producers in Yunnan, Hubei, Sichuan, Guizhou and Shaanxi, consolidate, check each lot against your specification, and arrange export. Producer documents are passed through unchanged.
What we do not do We are not a manufacturer and we claim no certificates. We do not sell to consumers and we do not give medical advice. Where the evidence is thin we say so.
