Konjac Powder Usage and Synthesis.

Konjac fine powder, also known as konjac flour or konjac mannan, is an extract of konjac. Konjac is beneficial alkaline food, for people who eat too much animal acidic food, with eating food made of konjac, you can achieve the acid-base balance of food, beneficial to human health.

Konjac is a tuber flat round, like a large water chestnut, very nutritious, containing a variety of vitamins and potassium, phosphorus, selenium and other mineral elements, but also contains human needs of konjac polysaccharide, and has a low-calorie, low-fat and high-fibre characteristics.

Mainly produced in the eastern hemisphere tropical, subtropical, China is one of the places of origin, Sichuan, Hubei, Yunnan, Guizhou, Shaanxi, Guangdong, Guangxi, Taiwan and other provinces and mountains are distributed.

Konjac food is not only tasty, pleasant taste, but also weight loss and fitness, treatment of disease and anti-cancer effects, and is known as "magic food", "magic food", "health food". etc.

Uses and functions of Konjac.

1, activate blood stasis konjac is pungent and warm in nature, has the effect of promoting blood flow, preventing stasis. Konjac contains mucin can reduce the accumulation of cholesterol in the body, preventing atherosclerosis and prevention of cardiovascular diseases.

2, anti-cancer swelling konjac has an interfering effect on cancer cell metabolism, drug sensitivity test proved that it is sensitive to pancreatic cancer, colon cancer cells, can dissolve phlegm and soften the hardness, dispel swelling and detoxification, the main treatment of lumps, phlegm nuclei, scrofula and other diseases, can prevent and control cancer.

3, laxative, reduce the absorption of fat konjac fibre can promote gastrointestinal motility, laxative, prevent constipation and reduce intestinal fat absorption, is conducive to the treatment of intestinal diseases, and can reduce the accumulation of cholesterol in the body, on the prevention and treatment of hypertension, coronary arteriosclerosis has important significance.

4, hunger weight loss konjac is a low-calorie food, which contains glucomannan will absorb water to expand, can increase to the original volume of 30 to 100 times, and thus after eating a sense of satiety, can be used for the treatment of diabetes, but also the ideal weight loss food.

Characteristic of Konjac.

White or cream to light brownish yellow powder. Can be dispersed in hot or cold water with pH 4.0~7.0 and form high viscosity solution. Heating and mechanical stirring can increase the solubility.

If a medium amount of alkali is added to the solution, it can form a heat-stable gel that does not melt even when strongly heated. Light yellow to brown powder. Basically odourless and tasteless.

Its aqueous solution has strong trailing (drawing) phenomenon and high consistency. Has a certain decomposition ability to fibrous substances. Soluble in water, insoluble in ethanol and grease. The main components are polysaccharides.

Product Method of Bulk Konjac Powder.

By should be Jian genus (Amorphophallus) various plants of the tuberous roots after drying after peeling, slicing, drying, crushing, sieving of the fine powder, called "konjac powder", the rate of about 60% ~ 80%. By β-1,4 glycosidic linkage of D-glucopyranose and D-mannose, accounting for 70% to 80% of the total amount of dry matter, particle diameter of 0.15mm or so, due to the particles covered with non-glucosidic glycans, affecting the water absorption, the gel capacity is low.

For this reason, physical modification with ethanol, petroleum ether, etc. can be used to improve the properties of water solubility, solubility viscosity, dissolution speed, etc. For this purpose, the tuberous roots can be sliced, crushed and immersed in ethanol, dried under reduced pressure at 60 ℃, degreased with petroleum ether, solubilised by adding sodium hydroxide solution and filtered, filtrate extracted with hydrochloric acid neutralisation and then lead acetate extraction, filtrate was taken, passed through hydrogen sulphide to remove the lead ions, ethanol was added to precipitate, centrifugal separation was carried out with Acetone drying, first for the crude product, and then dissolved in sodium hydroxide, filtration, hydrochloric acid neutralisation and concentration, ethanol precipitation, centrifugation and then acetone drying and get fine products, called "konjac fine powder".
