Our angle

Konjac has been a food for fourteen centuries. The marketing copy is recent. We try to keep them apart.

What konjac is A perennial root crop. The underground corm yields konjac flour and konjac glucomannan — a water-soluble fiber that swells to roughly two-hundred times its own weight when hydrated.

Why people care Shirataki fits a low-carb plate. Glucomannan has EFSA-authorized claims for weight loss at 3 g/day and cholesterol at 4 g/day. Konjac jelly is a familiar Asian snack. Sponges scrub kindly.

How we help buyers We supply konjac glucomannan and konjac flour at wholesale, with specification sheets, COA support, and MOQ flexibility for new product lines — food-grade, supplement-grade, and bulk powder.

Where we draw lines We name tradeoffs. Shirataki has a faint pondy odor when first opened. Mini-cup konjac jelly has documented choking-hazard advisories. Not every glucomannan study has shown the same weight effect.
