Amorphophallus konjac has strong adaptability to climate and soil, low planting cost, simple management, easy cultivation and processing, wide edible, medicinal and industrial uses, low cost and high economic benefits, and is being deeply studied, developed and widely used.
Konjac is a big family, with about 130 species in the world and more than 30 species in China, which are widely distributed in the southwest and the middle and lower reaches of the Yangtze River. Originally wild, it has been introduced and improved into cultivated plants, and its economic value and quality have been greatly improved.
Amorphophallus konjac is the only cash crop that can provide glucomannan in large quantities, which shows a wide application prospect in food, medicine, printing and dyeing, oil drilling and other industries. With the development of science and technology, the application value of konjac will be continuously developed and displayed.
The edible value of konjac is the main reason why it is widely welcomed by people and has a long planting history. At present, the biggest consumption of konjac is eating. The main component of konjac is glucomannan, which not only contains 10 kinds of amino acids and trace elements needed by human body, but also has the characteristics of low protein, low fat, high fiber, strong water absorption and high expansion rate. It can be used as the main and auxiliary materials of bionic vegetarian food, konjac jelly, ice cream, puffed ice cream, ham sausage, candy, milk, flour products, beverages and other products, and can also be directly made into various foods.
Glucomannan is widely used as a food additive because of its good water solubility, gelation, water retention, excipient, suspension, stability, film-forming, adhesion, high purity, good transparency, no odor, high viscosity, large expansion coefficient, rapid dissolution and strong compatibility. Glucomannan is also an excellent dietary fiber, which can be made into very popular functional food. At the same time, glucomannan is also an efficient and economical natural fruit preservative.
The medicinal value of konjac is also very high. Has the effects of reducing blood fat, blood sugar and blood pressure, losing weight, caring skin, promoting health, and relaxing bowels. Amorphophallus konjac is widely used in industry.

Amorphophallus konjac, alias Amorphophallus konjac, Amorphophallus konjac taro, Amorphophallus konjac, Ophiopogon japonicus, Amorphophallus konjac. Native to East India and Sri Lanka, there are primitive species in the tropical forests of East India. It is widely cultivated in tropical and subtropical Asian countries. China is cultivated in Yunnan and Sichuan provinces and the middle and lower reaches of the Yangtze River.
Cultivated population of perennial herbs of Amorphophallus in Araceae. Konjac tuber is rich in starch and pectin, which is toxic. They must be boiled with lime water before they can be eaten or brewed. They are often used to make konjac tofu. It also has the effects of reducing blood lipid, serum cholesterol, reducing swelling and attacking toxin, and is also an important additive and chemical raw material.

Amorphophallus konjac is a perennial herb, the main component is glucomannan, which contains many amino acids and minerals such as calcium, zinc and copper that cannot be synthesized by human body. It is a high-quality dietary fiber with low fat, low sugar, low calorie and no cholesterol. Konjac glucomannan has the characteristics of hydrophilicity, gelation, antibacterial, edibility and low calorific value. It can be used as gel, emulsifier, thickener, stabilizer and filler. It has broad application prospects not only in food processing, but also in medicine and health care industries.
Konjac has a long history as a food raw material, and there are more and more varieties of Konjac food, mainly including Konjac vermicelli, Konjac silk knot, Konjac powder skin, Konjac tendon, Konjac plum blossom, Konjac butterfly, Konjac shrimp, Konjac tofu, Konjac noodles and so on. The consumption of konjac food in Yunnan, Guizhou, Sichuan, Guangdong, Fujian and other places in China is relatively large. Consumers in Jiangsu, Beijing, Shanghai and other places have gradually improved their understanding of konjac food and its health care function, and their consumption is on the rise.
Konjac food has been recognized as "precious natural health food" by FAO. The health function of konjac food lies in the unique physical and chemical properties of glucomannan.
1. Purify blood: Konjac glucomannan can effectively inhibit the absorption of lipolytic substances such as cholesterol and bile acids in the small intestine, promote the excretion of fat, reduce the entry of fat and cholesterol into the blood, and reduce the total amount of triglycerides and cholesterol in the serum, so it can play a role in preventing hypertension, hyperlipidemia and cardiovascular diseases. According to relevant data, the human body can achieve the above effect by taking 3 grams of konjac glucomannan every day (three times) and persisting in eating for a long time.
2. Scavenger of gastrointestinal tract: A large number of studies show that the unique bundled hydrogel fiber of konjac can keep the intestine full, promote the physiological peristalsis of the intestine, soften the feces, speed up defecation, reduce the pressure of the intestine and relieve constipation.
3. The bane of intestinal cancer: the unique bundle hydrogel fiber of konjac can promote the rapid elimination of heavy metal elements and food toxic substances in the intestine, reduce the contact time between harmful substances and the intestinal wall, prevent the intestinal tract from absorbing these substances, remove the residues in the stomach, intestine and gallbladder, and effectively reduce the probability of harmful bacterial infection in the colon and rectum. It is an ideal cancer prevention and health food.
4. Good news for diabetic patients: Due to the high viscosity of konjac glucomannan, the viscosity of chyme in the digestive tract is enhanced, the retention time of chyme paste in the stomach cavity is delayed, and a protective film is formed on the intestinal wall, which effectively inhibits the rise of blood sugar value and urine sugar value. Experts at home and abroad have confirmed that konjac food is an ideal food for diabetic patients, which can reduce blood sugar, improve symptoms and control the disease.
