What is Glucomannan Flour?

Glucomannan is a milklike white or brownish powder, usually odorless and unsavory. It can be dispersed in acidic warm or cold water. Home heating or mechanical mixing can improve its solubility. Adding a certain quantity of antacids to its service can create For thermally safe sol, the liquid option uniformity is really high. Mannan is an all-natural high-molecular water-soluble polysaccharide with numerous -OH on its fragment. It is a hydrophilic substance, conveniently soluble in water, yet insoluble in all-natural solvents such as methanol and ether, and has wonderful swelling homes. The water absorption ability can reach worrying 100 times its really own mass. Konjac glucomannan has unique gel homes. Under non-alkaline conditions, it can have a solid teaming up outcome with carrageenan, xanthan gum cells, starch, and so on to improve the density of the solution.

Glucomannan Flour Structure

Konjac glucomannan was discovered in Japan at the end of the 20th century. It is made up of glucose and mannose residues with a molecular ratio of 1:1.5 ~ 1.6 (blossom konjac) or 1:1.69 (white konjac) polymerized via β-1,4 glycosidic bonds. It consists of regarding 3 branch chains for every 32 sugar residues. The branch chains are a number of residues long, and concerning every 19 sugar deposits have 1 acetyl team bound by an ester bond. There are several -OH on the monomer molecule, every one of which have solid reactivity.


Glucomannan Flour Application

Glucomannan Flour Pharmacological Effects

1. The outcome of KGM on sugar metabolic process
Konjac food is an optimum food for diabetics. It has the influence of decreasing blood sugar, enhancing signs and symptoms, and taking care of the condition. In clients with type diabetic person problems mellitus treated with Compound Konjac Granules, it was discovered that the fasting blood sugar decreased by 53%, the 2-h postprandial blood sugar level decreased by 51%, and the glycosylated hemoglobin decreased by 59.9%.

2. Impact of KGM on lipid metabolism
KGM impacts lipid metabolic process and has obvious hypolipidemic result. In addition to minimizing cream cholesterol in rats, konjac additionally has the outcome of turning around fatty liver. In addition to its superb blood-lipid-lowering and obvious anti-fatty liver results, konjac powder has no negative outcomes on the absorption and use of Ca, Fe, Zn, and Cu.

3. The weight-loss result of KGM
KGM is a low-calorie weight-loss food with obvious fat loss result.

4. The outcome of KGM on anti-cancer and immune function
Glucomannan Flour can have varying levels of repressive and preventive impacts on lung cancer cells in computer mice produced by methylnitrosoguanidine (MNNG). The variety of pets with generated cancer cells and precancerous sores is significantly minimized, and the proportion of fatal lumps in lump kinds is lowered. Konjac powder has the impact of considerably promoting the immune function of computer mice, raising the thymus index and spleen index, and creating macrophages (M) to manufacture and release interleukin-1 (IL-1) and tumor death factor-α (TNF-α) has a considerable advertising effect. Moreover, computer system mice additionally have a details marketing result on TNF-α levels in lotion. Consequently, KGM is expected to be taken advantage of as an immunomodulatory auxiliary item for the therapy of growths. Additionally, KGM was furthermore found to have a repressive outcome on spontaneous liver cancer cells, β-galactosamine-induced liver injury computer mice, and colon cancer cells.

5. Influence of KGM on digestion function
Konjac food can enhance the ordinary everyday fecal wet weight and fecal water web content, and can lower the digestive system transit time and the typical defecation time.

6. Effect of KGM on cell aging
Long-lasting usage of Glucomannan Flour can lengthen the aging procedure of mind glial cells, cardiomyocytes, and huge and medium-sized artery intima endothelial cells, stop atherosclerosis, and boost cardiovascular, mind, and vascular features.

7. The result of KGM on the absorption of trace element
KGM had no outcome on the fecal discharging, item, and femoral parts of the 4 elements Ca, Fe, Zn, and Cu in rats. Human experiments have really disappointed any type of kind of outcomes on the absorption of Zn, Fe, and Ca. There were no substantial alterations in the lotion calcium and phosphorus material, femoral weight, bone calcium and phosphorus internet content and bone morphometric requirements of rats taking in KGM, and no negative results were uncovered on calcium and phosphorus metabolic price and femoral calcium material.

Glucomannan Flour Preparation Method

Biological removal of glucomannan from konjac:
1. Enzyme treatment technique
Take 1 g of konjac powder, add water to make a homogenate (21 ° Baume focus), after that add a percentage of 2 000 μ α-amylase, dissolve it at 60 ° C for 45 to 60 minutes in the pH variety of 5.7 to 6.2, and disinfect at 110 ° C 5 mins, after that awesome and afterwards readjust the pH to 4.8 ~ 5.0. Include a percentage of 40 000μ glucoamylase, shake and saccharify at regarding 30 ° C for two days. After that disinfect at 110 ° C for 5 minutes. After cooling down, include 100 ml of water and filter to obtain the filtrate. After that make use of the adhering to There are two ways to refine the filtrate.

( 1) Fehling’s reagent precipitation method
Include 100 ml of Fehling’s reagent dropwise to the filtrate under strenuous mixing, and the glucomannan-copper compound precipitates in the form of a blue gel. Allow it stand till say goodbye to speeds up precipitate, filter under minimized stress, and precipitate with 80% ethanol (( including 3% HCl), rinse till white, completely dry at 40 ~ 50 ℃ and weigh.

( 2) Straight ethanol precipitation method
Under strenuous mixing, add an equal quantity of 95% ethanol to the filtrate. After the enhancement is full, continue stirring for thirty minutes and let it stand till say goodbye to precipitate speeds up. Filter under decreased stress, wash the precipitate with 80% ethanol until it becomes white, and breed at 40 ~ Dry and weigh at 50 ℃.

2. Saccharification method of saccharifying microorganisms
Take 2 g of konjac powder, include 100 ml of water and stir to develop a gel. Sanitize at 121 ° C for half an hour, inoculate saccharifying microorganisms after cooling down, and breed with drinking at 30 ° C for 20 to 24 hours to saccharify the starch. Add the saccharified mix Sterilize at 110 ° C for 5 minutes. Great and after that filter under lowered stress. Add an equivalent quantity of 95% ethanol to the filtrate under energetic stirring. Allow it stand till say goodbye to precipitate speeds up and afterwards filter. Rinse the precipitate with 80% ethanol till it ends up being white. Dry at 40 ~ 50 ℃ and evaluate.
