General Comment
2011-06-29 A dietary fibre obtained from tubers of Amorphophallus konjac (also known as devil's tongue or snake palm), glucomannan is used commercially as an emulsifier and thickener in the food industry. Flour from the konjac tubers is used to make Japanese shirataki noodles, which are very low in calories. Glucomannan can absorb up to 200 times its weight in water, so it is also used for absorbent articles such as disposable nappies.
