Embodiment Construction
[0035] The present invention will be further described below in conjunction with the examples and experimental results.
[0036] The following examples adopt chitosan produced by Jinhu Shell Products Co., Ltd.
[0037] One, the measuring method of the critical relative humidity of sample in the embodiment is:
[0038] Place the weighing bottle in a glass desiccator and dry it in a phosphorus pentoxide desiccator to constant weight. Fill the bottom with different saturated salt solutions (respectively CH 3 COOK, MgCl 2 、K 2 CO 3 , NaBr, KI, NaCl, KCl, Na 2 HPO 4 Saturated saline solution, relative humidity of 20%, 33%, 43%, 58%, 69%, 75%, 84%, 98%) was placed in a constant temperature incubator at 25 °C for 24 hours. Take 14 parts of Qilu Yishen extract powder prepared according to the process, divide it into 2 groups, each group has 7 parts, each part is about 1 g, put it at the bottom of the weighing bottle with constant weight, place it in a desiccator after accurat...
