What is Konjac?

Konjac is processed from a root plant of the same name belonging to the Araceae family and is native to Southeast Asia. Glucomannan, the water-soluble fiber found in konjac root sets with an alkaline coagulant. Konjac is composed of 96-97% water, except for glucomannan, the key ingredient. Glucomannan passes through the human digestive tract mostly undigested and is partially converted into fatty acids by microorganisms in the the gut. It is considered one of the lowest calorie foods (5-7 calories per 100g) and is commonly used as an ingredient when calorie intake needs to be restricted.
