Koch Author: [Chloé Blanchard](https://www.mynaturalorigins.com/en/blog/author/chloe-blanchard) Published On: November 10, 2022 Published In: [Food & Beverage](https://www.mynaturalorigins.com/en/blog/tag/food-beverage), [Life Science & Nutrition](https://www.mynaturalorigins.com/en/blog/tag/life-science-nutrition) Konjac Amorphophallus Konjac K. Koch is a tuberous rhizome of the Araceae family native to southern China, which grows in the countries of Southeast Asia. We find it being mentioned in very old Chinese writings. ## **Konjac: an old plant with health benefits**   Formerly grown and consumed in starch form during food shortages, it was particularly used in Chinese traditional medicine to reduce intestinal disorders, prevent tumours and sooths burns. It was also indicated as a cough medicine and in treatments used for asthma, hernias and haematological and skin diseases (1). The konjac rhizome contains a large quantity of mannan which produces mannose sugar (2). A gelatinous paste which expands in contact with water is obtained from konjac flour. This acts as an appetite suppressant and can also be used to prepare pasta, snacks and tofu dishes of the Far East.     ## **Exceptional slimming properties**   On the agro-food market, konjac is a trendy food largely used as a thickener in the form of purified flour, called glucomannan extracted from the root of the plant (3). It can be found in desserts, puddings, cooked dishes and especially in the food supplement field. Konjac is essentially made up of soluble fibre beneficial for the microorganism of the intestine. Once ingested, this forms a covering of the intestine and produces a feeling of being full. Glucomannan can absorb up to 100 times its weight in water! As such, konjac is a good weight loss ally, especially for athletes’ diets, which the food supplement market has developed mainly based on its slimming properties and its low calorific value (3kcal/100g).     ## **A unique food in its kind**   There are numerous therapeutic benefits of konjac: it participates in lowering bad cholesterol, preventing cancer and diabetes, and absorbing fat and sugars limited by the rhizome’s active ingredients. Konjac fibres slow down the absorption of sugar, thus promoting good blood glucose concentration levels contributing also to improving metabolism with regard to insulin levels (4). Konjac glucomannan is moreover beneficial for proper intestinal functioning (5) and preventing certain chronic diseases. Consumers endorse it for its slimming advantages: a healthy, low calorie and rich in fibre food. Over 30% of konjac based products claim having a "high fibre content" and are positioned around losing and controlling weight (6) . Our konjac sourcing comes from China.
