通过不同毛木耳粉体对吸附水、油脂及重金属离子能力影响的研究发现，毛木耳粉体吸附性优于未粉碎的子实体。选择粉体粒度在40目、100目、300目的样品，并以未粉碎的毛木耳样品为对照，进行吸附试验。结果表明，粉体粒度越细，毛木耳的吸附能力越强。在吸附水分方面，300目样品饱和吸水量为17.12 g/g，与对照组（6.13 g/g）相比，吸附水分能力提高179.3%；在吸附油脂方面，300目样品饱和吸油量为1.06 mL/g，与对照组（0.37 mL/g）相比，吸附油脂能力提高186.5%；在吸附重金属离子方面，在Cd2+离子浓度达到10μg/mL时，300目样品的吸附量分别为165.80μg/g，与对照组的吸附量55.23μg/g相比，吸附能力分别提高了200.2%，在Pb2+离子浓度达到10μg/mL时，300目样品的吸附量为196.08μg/g，与对照组的吸附量85.95μg/g相比，吸附能力提高了128.1%。

Through the effect of adsorption capacity on different Auricularia polytricha powder on adsorbed water, grease and heavy metal ions, found the adsorbability of Auricularia polytricha powder batter than ungrinding fruiting body. Experiment was conducted through selected the samples on powder granularity of 40-mesh, 100-mesh, 300-meshs, and the ungrounding samples as control. The results show that, the finer the powder granularity, the stronger adsorption capacity of Auricularia polytricha. On the adsorption of water, the sample of 300-mesh saturated adsorption capacity was 17.12 g/g, and compared to the control group (6.13 g/g), 179.3 % adsorption capacity was increased; on the adsorption of oil, the sample of 300-mesh saturated adsorption capacity was 1.06 mL/g, and compared to the control group (0.37 mL/g), 186.5%adsorption capacity was increased;on the adsorption of heavy metal ions, the ion concentration of Cd2+was 10μg/mL, t300-mesh saturated adsorption capacity was 165.80μg/g, and compared to the control group (55.23μg/g), the adsorption capacity was increased by 200.2%, the ion concentration of Pb2+was 10μg/mL, 300-mesh saturated adsorption capacity was 196.08μg/g,and compared to the control group(85.95μg/g), the adsorption capacity was increased by 128.1%.
