Konjac flour, also known as konjac flour or konjac mannan, is an extract of konjac.Konjac is a beneficial alkaline food.For people who eat too much acidic food from animals, eating foods made from konjac can achieve the acid-base balance of the food, which is beneficial to human health.Konjac is a tuber flat-shaped, like a big water chestnut. It is very nutritious. It contains a variety of vitamins and minerals such as potassium, phosphorus, and selenium. It also contains konjac polysaccharides that humans need, and has low calorie, low fat and high fiber.element characteristics.

Product Description:
Glucomannan is a natural, water-soluble polysaccharide derived from the root of the Konjac plant (Amorphophallus konjac), which is native to Southeast Asia. It has been used for centuries in traditional Asian medicine and cooking, particularly in Japanese cuisine, where it is a key ingredient in foods like konjac noodles (shirataki noodles) and konjac jelly.
Glucomannan is most commonly consumed as a dietary supplement, often marketed for its potential health benefits, particularly for weight management, cholesterol reduction, and digestive health.
Health Benefits of Glucomannan:
-
Weight Loss:
- Appetite Control: Glucomannan's ability to expand in the stomach may help reduce hunger and promote feelings of fullness, leading to a natural reduction in calorie intake.
- Supports Weight Management: Studies have shown that glucomannan supplementation, when combined with a calorie-controlled diet, can lead to modest weight loss in some individuals.
-
Digestive Health:
- Constipation Relief: Due to its high fiber content, glucomannan may help improve intestinal health by adding bulk to stools and promoting regular bowel movements.
- Gut Health: As a soluble fiber, it acts as a prebiotic, providing nourishment for beneficial gut bacteria, which supports overall gut microbiota balance.
-
Cholesterol and Blood Sugar Control:
- Cholesterol Reduction: Glucomannan may help lower total cholesterol and LDL cholesterol levels by binding to bile acids and preventing their reabsorption, promoting the excretion of cholesterol.
- Blood Sugar Regulation: Preliminary studies suggest that glucomannan may assist in controlling blood sugar levels, making it potentially beneficial for individuals with type 2 diabetes or those looking to manage blood glucose levels.
-
Heart Health:
- By lowering cholesterol levels and supporting blood sugar regulation, glucomannan may contribute to cardiovascular health.
Uses of Glucomannan:
-
Dietary Supplement:
- Glucomannan is commonly sold as a dietary supplement in the form of capsules, tablets, powder, or shakes. It is typically consumed before meals, where it expands in the stomach and helps control appetite.
-
Food Additive:
- In the food industry, glucomannan is used as a thickening agent and gelling agent. It is often found in products like noodles (shirataki noodles), jellies, sauces, and low-calorie snacks.
-
Functional Foods:
- Glucomannan is also used in the production of weight-loss beverages, dietary bars, and other low-calorie foods.
Dosage and Usage:
-
Typical Dosage: The recommended daily dosage of glucomannan typically ranges from 1 to 3 grams per day, taken before meals with plenty of water. It's important to follow specific product instructions or consult a healthcare professional for personalized advice.
-
Important Considerations:
- Glucomannan should be taken with plenty of water (at least one glass) to prevent choking or blockage in the throat or digestive system due to its high absorbent properties.
- Always start with a small dosage to assess your tolerance, especially if you have any digestive issues.

The main component of konjac gum is glucomannan, is a kind of low-calorie, low protein, high dietary fiber food, and of more than ten kinds of amino acids and trace elements, as a functional food, also has a water soluble, thickening, stability, suspension, gel, film, adhesive and so on a variety of physical and chemical properties, so it is a kind of natural health food are also the ideal food additives. Konjac as food and food additives USES very wide: As a thickener and stabilizer can be added to the jelly, jam, fruit juice, vegetable juice, ice cream, ice cream and other cold drinks, solid beverage, seasoning powder and soup powder; As binder can be added to the noodles, rice noodle, twisted in the skin, meatballs, sausages, bread and cakes to enhance thews and keep fresh state; As gels can be added to various kinds of jelly, candy, and crystal sugar, can also be used to make bionic foods.
Application of Konjac glucomannan
1. Application in the food industry: Making the gelling food, used as the food thickening agent and adherence agent such as the jelly ,ice cream, gruel, meat, flour food, solid drink ,jam etc.
2. Application in the health care industry : Modulate the metabolism of lipid , decline the serum triglyceride and cholesterol,improve sugar resistance and prevent the diabetes, relief the constipation and prevent intestines cancer, produce no energy and prevent the fatness ,modulate the immunity function.
3. Application in the chemical industry:Because the Konjac glucomannan average molecular weight of 200,000 up to 2,000,000 is so big, the viscidity is high, and the fluidity is good, it has been applied to the chemical industries such as petroleum, the dye printing cataplasm, the terra film, the diaper, the medicine capsule and so on.
Advantages of konjac powder:
1. Cleaning labels
Konjac flour is a food with cleaning label properties
2. High viscosity
