The invention provides a production method and an edible method of instant fungus silk. The existing fungus products cannot not be produced into the instant product and need to be subjected to secondary processing after being purchased for eating, thus being inconvenient for people, especially people in the busy work, becoming more inconvenient. The production method of the instant fungus silk comprises the following seven steps: step 1, purchasing the raw material fresh funguses; step 2, sorting the raw material fresh funguses purchased by the first step; step 3, recovering the sorted fresh funguses into native-state fresh funguses; step 4, cutting the recovered fresh funguses into silks; step 5, freeze-drying the recovered fresh fungus silks in the sorting step at an ultralow temperature; step 6, sorting the freeze-dried recovered fresh fungus silks at the ultralow temperature; and step 7, packaging the sorted freeze-dried recovered fresh fungus silks at the ultralow temperature, checking and putting in storage for selling. The production method provided by the invention is used for making edible fungus.
