1. the preparation method of a konjac glucomannan adsorbing material, step is as follows:

  • A, feedstock production;

    adopt the method for Chinese patent CN1328062A, the preparation high-purity kanjak glucomannosan;

    B, swelling;

    the high-purity kanjak glucomannosan that takes by weighing the steps A gained, add the ratio of 15~

    30ml water with its swelling 10min according to every 1.00g high-purity kanjak glucomannosan, adding methyl-sulfoxide to its concentration again is 6~

    10v/v%, under 40~

    70 ℃

    temperature, stir 90~

    180min, after making its abundant swelling, can obtain the high concentration konjak gel;

    C, granulation;

    getting the material extruding formation diameter for preparing among the step B is the filamentous of 0.5~

    1.0mm, immerse in the dimethyl sulphoxide solution of 70~

    95v/v%, place boiling water bath, take out behind the 30min, be cut into the particle that blade diameter length ratio is 0.5~

    1.0mm;

    0.5~

    1.0mm, 40~

    70 ℃

    are dried to constant weight, promptly get konjac glucomannan adsorbing material.
