Disclosed are suspension liquid of Ganoderma lucidum fruiting bodies and nano/submicron scale suspension liquid of Ganoderma lucidum fruiting bodies, wherein the suspension liquid of Ganoderma lucidum fruiting bodies is the liquid containing Ganoderma lucidum particles obtained by mechanical grinding of Ganoderma lucidum fruiting bodies, which also contains fiber, chitin, and &bgr； -glucan. The average particle diameter of Ganoderma lucidum particles is less than 10 &mgr； m. Such suspension liquid of Ganoderma lucidum fruiting bodies made by mechanical grinding is characterized in that the complete active ingredients can be obtained without any extraction operation. In addition, fiber surface area can be substantially increased, no further grinding operations are needed in the subsequent use of fiber, and can be used as a good meal fiber additives.一種靈芝子實體懸浮液，該靈芝子實體懸浮液為靈芝子實體經由機械式研磨後所得到含有靈芝微粒之液體，並含有纖維質、幾丁質，及β-葡聚糖，且靈芝微粒之體積平均粒徑小於10 μm。透過機械式研磨製成的靈芝子實體懸浮液，除了無須萃取即可獲得完整的活性成分外，還可大幅提高纖維質比表面積，且纖維質之後續利用無須再粉碎，可作為一良好的膳食纖維添加物。
