Storage Technology of dried Edible Fungi
First, dry before storage. The drying of edible fungi is mainly the removal of free water between cells. In order to facilitate storage, it is generally required that the moisture content of dry products should be controlled at 10-13%. Using the method of natural drying or artificial drying, the drying process is the process of vaporization of water in the material, that is, the energy absorbed by water molecules changes from liquid state to vapor state. Artificial drying is mainly convective drying, and the heat required is obtained through the continuous or intermittent contact of air or heating dry air flow, and at the same time, these air flows take away the evaporated water from the object to achieve the purpose of material drying.
