What is Glucomannan
Konjak is prepared from a kind of perennial herbage plant with low energy, low protein, and high fiber.It is known primarily for its starchy corm, a tuber-like structure that is actually part of the plants stem, but which grows underground and acts as a storage organ for the plant. Konjak glucomannan is the main component of konjak extract. Glucomannan is used as a food additive for its thickening and emulsifying properties, and as a nutritional supplement for the treatment of obesity, constipation, high cholesterol, diabetes and acne. In addition, Glucomannan powder contains more than ten kinds of amino acid required by human body, microelement and unsaturated fatty acid, it is effective in tumor resisting, blood health keeping and weight-control.
What are the benefits of Glucomannan
- Glucomannan prevents and reduces the incidence of intestinal system disease.
- Konjak extract can reduce the residence time of the harmful substances in the gastrointestinal and gall-hsiang, effectively protect the gastric mucosa,
clean the stomach wall. - Glucomannan can be used for inhibition of cholesterol, lowering blood pressure, lowering blood sugar, dilation of blood vessels, to prevent of atherosclerosis and other cardiovascular disease.
- Glucomannan has effect on prevention and treatment of diabetes.
- Glucomannan powder has significant effect on weight loss.
Applications of Glucomannan
- 1. Glucomannan powder can be applied in food field as raw material.
The viscosity of the aqueous solution of konjac glucomannan chitosan, high molecular weight, good rheological property and antibacterial properties of water holding capacity, and can be developed as a new type of non-toxic and pollution-free edible food packaging, are widely used in food additives and food preservation. Konjac Glucomannan as antistaling agent can form a layer of film with close permeability in the fresh food surface, making the food surface stomatal closure, reduce water evaporation, isolate oxygen into effect, thereby reducing food respiration, reduce nutrient consumption and water evaporation, and inhibit the entry and reproduction of bacteria. Thus, preservation and prolong the shelf life of effect. When using KGM for the preservation of fruits and vegetables, decrease respiration rate of fruits and vegetables, vitamin B loss rate and rot rate were decreased, while the flavor of fruits and vegetables to keep longer, showing good fresh-keeping effect. Biostrac by konjac glucomannan film coated on Longan at about 30 DEG shelf-life, results showed that: in longan surface of konjac glucomannan can effectively avoid deterioration in a short period of time the longan, through measuring the damage rate and weight loss rate were only 20% and 2.56%. The color and moisture of the pericarp were basically maintained. Under this condition, the shelf life could be extended to about 10 d. In addition, konjac glucomannan gel because of its excellent performance and cohesiveness of the works can also be used modifier for cake, noodles and other food processing, thereby increasing the adhesion, make the taste better. The use of konjac glucomannan in ice cream and ice cream frozen food can effectively improve the organization of the state, because of its good water holding capacity generation can effectively suppress the thick ice, thereby increasing the melting resistance of frozen food, make the taste more lubrication, improve its viscosity and expansion rate at the same time. The addition of konjac glucomannan in meat products such as ham sausage can significantly increase the cohesiveness and volume. Used in yogurt and condensed milk and other dairy products can play a role of stabilizer, can hold water, thickener and stabilizer in rice pudding and various beverages. - 2. Glucomannan powder can be used as raw materials in health care products and supplement field.
Konjac glucomannan in the human intestinal water absorption swelling, can promote gastrointestinal peristalsis, effectively reduce the absorption of harmful substances, timely conversion of intestinal waste into excreta excreted, so in the treatment of constipation, Runchang laxative, lipid-lowering and other diseases have a very good effect. Biostarct mixed konjac flour into food to study the levels of total cholesterol and low-density lipoprotein cholesterol in patients with hyperlipidemia. The results showed that: glucomannan can directly reduce blood lipids, so that the above indicators of 110 hyperlipidemia patients were significantly decreased. KGM also has the function of removing fat deposits in the cardiovascular system by reducing the absorption of cholic acid and cholesterol, increasing the excretion of cholic acid and cholesterol, and reducing the blood lipid and serum cholesterol
It is a good news for patients with diabetes, coronary heart disease, hypertension and other diseases. In addition, konjac glucomannan is a low calorie food, which can be used in the large intestine of the human body by microorganisms in the large intestine, but it can not be hydrolyzed by digestive enzymes, so it can be used as a good anti-cancer and slimming food in the field of health care. - 3. Glucomannan powder can be applied in cosmetic field as raw material.
Glucomannan is composed of glucose and mannose, containing a large number of hydroxyl, soluble in water, because of containing a large number of hydroxyl groups through hydrogen bonding adsorption of large amounts of water, thus has higher water holding capacity, even comparable to sulfated hyaluronic acid; also with proteins, peptides and other functions for the occurrence of each sub polar group the role of stability may also play a role; the oxygen and metal hydroxyl ligand, the heavy metal lock in the air, avoid the harm to the human body skin. - 4.Application in chemical industry
Konjac glucomannan through chemical modification of functional groups can be made of ion exchange chromatographic packing, the advantages of chromatographic packing: with excellent stability, insoluble in water, acid and alkali, high mechanical strength, high flow rate of liquid under strong, short regeneration time. In addition, it can also be used to produce immobilized enzyme, which has the advantages of reusable, good stability, high activity and low cost.
