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.
