Problems solved by technology

[0004] Konjac can contain high selenium (0.65-7.80mg / kg) in its tubers no matter in the natural high-selenium area or artificially applied selenium during the planting process, but the loss of selenium cannot be avoided during processing. Minimal or undetectable selenium content after glucomannan

Embodiment Construction

[0021] Example: Using the preparation method of selenized glucomannan of the present invention, elemental selenium and strong oxidant potassium permanganate are used for oxidation reaction to obtain Se 6+ After ionization, add 500 times deionized water, add 95% ethanol and concentrated hydrochloric acid to make the ethanol content in the solution 5% and hydrochloric acid content 1%; then add 15% glucomannan powder, heat the reaction solution, and control the temperature at At 40°C, after reacting for 15 minutes, cool to room temperature, add ethanol to make the ethanol content in the solution reach more than 30%, stand still to separate the precipitate, and dry the precipitated selenide glucomannan.

[0022] Implementation time

[0023] Through the production of selenized glucomannan, selenized glucomannan with a selenium content of 120 mg / kg or more can be obtained.

Abstract

The invention discloses a selenoglucomannan preparing method, combining the selenium with glucomannan on a certain condition to achieve the purpose of producing selenium-containing selenoglucomannan. It oxidizes the selenium into Se6+ ion water solution by oxidant; takes the Se6+ ion water solution and adds in alcohol and hydrochloric acid, to make the alcohol content in the solution at 5%-10% and hydrochloric acid content at 1% about; adds glucomannan in a seleno-reaction liquor to make seleno reaction; adds in alcohol to deposit selenoglucomannan; separates and dehydrates selenoglucomannan deposit, and then dries to make it at once.

Description

Technical field [0001] The invention relates to a preparation method of selenized glucomannan. Background technique [0002] The trace element selenium (Selenium, Se) is an essential trace element for the human body. It has the important functions of anti-oxidation, scavenging free radicals, anti-cancer, improving and regulating immune function, and has physiological effects similar to insulin. Konjac is a tuber of Araceae (Amorphophallus blume) perennial herb, which is widely distributed in the Yangtze River Basin and the south. Konjac is rich in glucomannan (K·glucomanan, KGM), which has important health care functions such as lowering blood lipids, lowering blood sugar, clearing the intestines, suppressing tumors and enhancing immune functions, and important physiological functions such as anti-oxidation and scavenging free radicals. [0003] Combining the advantages of the rich glucomannan and selenium in konjac organically, the two functions complement and multiply, and furt...
